testbed
changes made within the testbed to your epp password will affect only the testbed, and will persist only until the next reset cycle. no data in the testbed will be copied to the live register .
work on testbed 14 commenced with the elicitation of sponsor requirements in 2017. among the organizations providing testbed sponsorship are the following ogc members :
a whois server is available for the testbed to assist with testing. the testbed server is at testbed - whois. nominet. org. uk. usage limits of 100, 000 requests per day are in force .
testbed is the primary api for writing unit tests for angular applications and libraries .
a list of signees of the atis testbed confidentiality agreement can be found here .
atis robocalling testbed connectivity guidelines - participants who have returned both the atis confidentiality agreement and neustar robocalling testbed use policy can request the latest copy by contacting technical support .
testbed is a common way to describe testing rooms at robotics facilities. for example, a testbed may allow robot driven processes such as manufacturing steps to be tested .
if you have any questions about the atis robocalling testbed, please contact jim mceachern .
is a facility for conducting rigorous tests. the following are common types of testbed .
nine easy - to - follow examples using testbed, fixtures, async and fakeasync / tick .
testing utilities: testbed, inject, fixtures, async, fakeasync / tick and jasmine. done .
your epp password for the testbed (and the associated ip address) can be changed via the online service. such changes will be reflected in the testbed after the next daily reset cycle. changes to the
information regarding the wfs 3. 0 hackathon, which will feed results into testbed 14. is now available .
testbed, similarly to @ ngmodule helps us to set up the dependencies for our tests. we call testbed. configuretestingmodule passing our configuration. this information will then be used to resolve any dependencies. we can see an example below :
these details can be changed at any time, and will be reflected on the testbed server only after its next reset cycle .
for dependencies defined at the component level we need to use the component injector as shown above. testbed. get or inject won’t work .
on the testbed, a clone of all tags on the testbed has been provided - all connection ip addresses are the same. this tag can be used to transfer a domain name to your tag and generate a notification. the name of the cloned tag is generated as follows :
to test create requests which are referred for manual intervention, applications made to the testbed for domain names ending
urltoken
are validated automatically .
first we load the dependencies required for our tests with testbed. configuretestingmodule. then on our spec we use inject to automatically instantiate each dependency .
the term testbed is primarily associated with the testing of aircraft engines. this typically means fixing the engine to a fixed location and testing it on the ground. engines are also tested on a
flying testbed
meaning an aircraft fitted with both its original engines and an engine that' s in development .
the testbed environment is as close to the live environment as possible. consequently, any (fictional) domain created in the testbed must have a unique name. in order to avoid potential name conflicts with other tags, it is suggested that you append your tag - name to the key of any domains you request .
we used testbed. createcomponent to create an instance of our greeter component. the component instance will be accessible within a fixture. this is its main api :
noaa' s hydrometeorolgy testbed (hmt) is a joint oar — nws testbed motivated to make communities that are more resilient to the impacts of extreme precipitation on lives, property, water supply and ecosystems. hmt is co - managed by the oar physical sciences division, and the nws weather prediction center in partnership with the national water center .
flight evaluations for the rolls - royce trent xwb engine – which will power airbus’ new a350 xwb jetliner – began aboard the dedicated a380 testbed aircraft on 18 february, 2012 .
the engine for airbus’ new a350 xwb jetliner made its successful first flight on 18 february, 2012, installed aboard the dedicated a380 testbed aircraft on its inner left wing position .
testbed 14 is organized into the following threads. these will integrate both architectural and thematic views, allowing a grouping of closely related work items and reduction of cross - thread dependencies .
the testbed database provides each registrar with a set of fictional domains, accounts, and contacts. the dataset is provided solely for testing purposes, and registrars are free to alter the data, and register new domains and accounts. the dataset will be reset daily, discarding any changes and additions made. two testbed servers will be available, a secure epp server using tlsv1. 2 and a plain - text server. both servers will connect to the same testbed database. the secure epp server provides server authentication and data encryption but does not require ssl client authentication .
objects existing in the live registry, such as domains and registrant accounts, are not replicated in the testbed. only a clone of your registrar account, and a clone of each tag which is registered to use epp, will appear in the dataset, with id values not matching those in the live register. aside from this, all information in the testbed will be fictional. a set of domains will be created on each tag, covering a variety of different states grouped together under a series of registrants (
ok, hopefully the testbed stuff helps to identify any bugs or performance issues. i' ve finished testcrankgearspulley now, and started on testedges. i' m including cranks and pulleys since it was an easy update but i' m not sure how to proceed with testedges .
the testbed 14 call for participation (cfp) (
part 1 cfp
) is now closed, but offers of in - kind contributions on a best - effort basis (i. e. , not under any participation agreement contract) will still be considered. as stated in the cfp general proposal submission guidelines, any additional in - kind scope should be offered outside the formal bidding process, where an independent determination can be made as to whether it should be included in testbed scope or not. more information can be found in the solicitation document .
later this year, the enhanced ge90 engine will operate on ge' s 747 flying testbed aircraft at mojave, california. certification by the u. s. federal aviation administration (faa) is expected in december 1999. boeing 777 aircraft powered by the ge90 pip engine are targeted for delivery beginning in mid - 2000 .
the neustar trust lab serves as the virtual industry testbed for communications service providers, equipment manufacturers and software suppliers to remotely test solutions developed for the shaken framework. participants in the testbed collaborate to test against applicable atis standards. neustar provides technical support for the relevant connectivity information, representative network configuration, its shaken software functionality and supported test scenarios amongst participants. the virtual test environment removes obstacles and accelerates the validation of caller authentication standards. the facility supports extensive call tracing which helps quickly troubleshoot during testing sessions. through neustar’s content collaboration platform, detailed call traces are shared in almost real time and test results are formally published, summarized and shared at various levels .
the ogc innovation program provides a venue for using initiatives to advance solutions to data challenges through using open standards. testbeds are ogc' s largest initiatives, with last two testbeds averaging us $ 3 million in sponsor funding. most recently, testbed 13 was sponsored by 12 organizations from 5 countries, and brought together more than 200 individuals from 60 organizations .
meanwhile, ge’s stalwart ex - pan am operated 747 - 100 flying testbed, the oldest example of the 747 still flying, is busy wrapping up tests of the upgraded genx - 2b performance improvement package (pip) at victorville, calif. the upgraded engine - seen above in the number two (inboard positiion) - will power the 747 - 8 .
its distinct third - engine pylon is original, because when it comes to certifying a new engine, the test engine is usually installed by general electric or rolls - royce in place of one of the series’ reactors, present under the wing. however, honeywell’s testbed engine has its limits. it can only be used for small reactors weighing a maximum of around 700 kg .
testbed 14 will be ogc' s 100th initiative. over the course of past initiatives, ogc has helped develop new standards and architectures that have transformed how we share and use geospatial information, from advancing sharing of digital maps over the web (e. g. wms) to new encodings (e. g. geopackage) that are empowering mobile users with powerful geospatial tools .
the atis robocalling testbed, exclusively hosted by the neustar trust lab, serves as the industry interoperability test facility to validate the effectiveness of caller authentication standards developed by the internet engineering task force (ietf) and atis. specifically, atis developed “signature - based handling of asserted information using tokens” (shaken) as an implementation framework for service providers to better combat robocalls and call spoofing on ip - based networks .
the testbed is set up in a way that allows a new test to be added efficiently. when a new test is defined, only the parts of the code which make it unique need to be written. functions which are the same for all tests such as creating / destroying / resetting, and the control panel checkboxes and buttons, are handled by the main program code and never need to be changed .
, so if this default input (mouse dragging of objects etc) is enough, then you may not need to override the input functions at all. likewise if you are not doing anything special for rendering or physics control, you don' t need to override step () either. in fact, some of the example tests in the testbed are nothing more than a constructor to set up the scene. i told you it was simple didn' t i... ?
emulab is a network testbed, giving researchers a wide range of environments in which to develop, debug, and evaluate their systems. the name emulab refers both to a facility and to a software system. the primary emulab installation is run by the flux group, part of the school of computing at the university of utah. there are also installations of the emulab software at more than two dozen sites around the world, ranging from testbeds with a handful of nodes up to testbeds with hundreds of nodes. emulab is widely used by computer science researchers in the fields of networking and distributed systems. it is also designed to support education, and has been used to teach classes in those fields .
the newer 747 will provide greater capability than the 1960s - era legacy testbed in terms of a larger flight performance envelope, greater range and payload, and improved integrated systems. powered by cf6 - 80c2 engines, the 747 - 400 will have excess performance and better capability says ge. the current aircraft is barely able to achieve the 43, 000 ft required for 787 engine test points for sustained periods, whereas this will comfortably be achieved with the newer version, it adds. aside from greater range and endurance, up to 15 hours of flight time versus the 8 to 9 hour flights normally flown by the current 747, the newer aircraft is also configured with contemporary arinc 429 - based digital avionics .
general electric’s new boeing 747 - 400 flying testbed has been delivered to evergreen aviation technologies (egat) in taiwan for installation of data racks, instrumentation wiring and instrumentation equipment. the aircraft is also scheduled to undergo wing structural modifications during the second half of the year in readiness for its first test flights in 2014. the aircraft was flown to egat from taikoo aircraft engineering, xiamen, where heavy maintenance and interior modifications had been performed. ge, which continues to operate its original pratt & whitney jt9d - powered 747 - 100, acquired the ex - japan airlines - 400 in december 2010 as part of preparations for tests of a new wave of engines including the cfm leap - 1, passport business jet engine, genx derivatives and the forthcoming ge9x for the proposed 777x .

any service provider with an assigned operating company number (ocn), as maintained by the national exchange carrier association, inc. (neca), is eligible to participate. participation is free of charge. other parties, such as equipment manufacturers, may participate if they have solutions relevant to the shaken framework available to test .
unwanted robocalling and caller id spoofing has become a massive problem for consumers and the communication industry. as the number one complaint of the fcc, consumers are annoyed at the time they waste answering unwanted robocalls. consumers also don’t feel secure answering calls where the caller is not identified or may be falsely identified with millions lost to phone scams every year. enterprises and brands have a hard time getting a hold of their customers to share important information when they don’t pick up their calls or texts .
to address this recognized industry problem, an ietf working group drafted three related standards, which collectively define a means to authenticate the calling number, securely transport this information “on the wire” and verify it at the receiving end. to put these standards into action, the atis / sip forum ip - nni task force has developed shaken, a trusted identity framework that provides guidance for service providers implementing caller id network validation .
together, the ietf standards and shaken give service providers the tools they need to consistently authenticate, digitally sign and verify calling party numbers. this functionality enables network operators to stop suspicious calls before they reach their subscribers, or provide notifications that allow consumers to decide whether to answer a call. shaken also includes important capabilities to assist law enforcement in finding the source of unwanted calls .
results from the testing will remain confidential under non - disclosure agreements. aggregate and anonymized findings will be shared in the atis testbeds focus group to further advance caller id spoofing and robocalling solutions .

in this post, we want to cover the most common unit tests to use for angular applications, like: components, services, http and pipes; but also some less known areas like: directives, the router or observables. we will provide examples designed so you can use them as a quick reference. don’t miss out the testing checklist to help you while creating your own tests .
testing has been improved quite a lot from rc to final and even more after moving to ngmodule. the angular core team has worked hard to reduce boilerplate and be able to use not only jasmine but other tests frameworks like mocha .
there are few new apis you should know about to get the best out of your tests. we will cover :
testing examples: components, services, http and mockbackend, directives, pipes, routes, observables and eventemitter .
to test, all 26 specs or change the code, you can use this plunker .
jasmine is an open source testing framework from pivotal labs that uses behaviour - driven notation resulting in a fluent and improved testing experience .
suites — describe (string, function) functions, take a title and a function containing one or more specs .
specs — it (string, function) functions, take a title and a function containing one or more expectations .
expectations — are assertions that evaluate to true or false. basic syntax reads expect (actual). tobe (expected )
matchers — are predefined helpers for common assertions. eg: tobe (expected), toequal (expected). find a complete list here .
jasmine offers four handlers to add our setup and teardown code: beforeeach, aftereach executed for each spec and beforeall, afterall executed once per suite .
a good practice to avoid code duplication on our specs is to refactor repetitive code into the setup .
there are few options to setup your environment. you can use jasmine’s specrunner. html from the standalone distribution to start or create your own. you can also integrate it with a test runner like karma. we are not going to cover all combinations as we are more interested in the actual tests .
we load jasmine dependencies followed by angular ones. we are using a system. js and typescript setup. we use promise. all () to load our specs in one go and, once all specs are available, we trigger jasmine test - runner manually by calling onload .
we can now refactor the inject so we don’t repeat it for each spec .
let’s see two examples of instantiating a component. the first example, is synchronous and creates a fixture containing an instance of mytestcomponent .
second example, is asynchronous, as is using external templates and css, requiring xhr calls .
we can use async when dependencies involve asynchronous handling. this will internally create a zone and deal with any asynchronous processing .
can i use mocks, stubs or spies? dependencies should be covered by their own tests. using them can boost your tests without losing efficacy .
sync or async? does your test makes asynchronous calls? uses xhr, promises, observables, etc. is the component using templateurl or styleurls or inline? make sure you are using the corresponding apis .
let’s see how we can test the different building blocks of our application. we are going to skip all required imports for brevity. we added notes when necessary. they can be found here .
let’s take a simple component that renders a greeting message using an @ input () property .
a common practice is to use beforeeach to refactor our tests. by doing it, we avoid having to repeat some code like inject for each test. this will also simplify our specs .
we used the name property to set up a value, trigger change detection with detectchanges and check the expected result when all asynchronous calls have ended using whenstable. in order to access the rendered text we used two different apis filtering by a css selector (lines 22–23) .
other queries for debugelement are: query (by. all ()) query (by. directive (mydirective) )
languagesservice has only one method that returns an array of available languages for the application .
similar to our previous example we instantiate the service using beforeeach. as we said, this is a good practice even if we only have one spec. on this occasion, we are checking each individual language and the total count .
we usually don’t want to make http calls during our tests but we are going to show it as a reference. we have replaced our initial service, languageservice for languageservicehttp .
in this case it uses http. get () to read a json file. we then used observable. map () to transform the response into the final result using json () .
our test looks very similar to the previous one. the main difference is the use of an asynchronous test as we did with the component due to the subscribe .
http. get () returns an observable that we can subscribe to. we will cover observables in more detail later on .
a more sensible approach is replacing http calls with a mockbackend. in order to do this, we can use provide (line 10). this will allow us to mock our responses and avoid hitting the real backend, therefore, boosting our tests .
on our test we build our mocked response (lines 23–25) so when we finally make the call to our service it gets the expected results .
directives in angular are a specific type of component with usually no accompanying view. we will use an attribute directive, logclicks, that logs how many clicks we do on the host element so you can grasp the idea .
in order to test this directive, we decided to create a container component. we will set it up so it will act as our host reproducing the events emitted by our directive .
we used beforeeach to separate the logic for creating the component from the tests. this part can now be used for all specs .
to trigger the click on the container we used the dom api (recommended). we could also use fixture. debugelement. triggereventhandler (‘click’) .
in this test, we used fakeasync and tick. using fakeasync all asynchronous processing will be paused until we call tick. this gives us greater control and avoids having to resort to nested blocks of promises or observables .
using fakeasync / tick we get greater control of the asynchronous code although it can’t be used with xhr .
pipes are functions that can transform input data into a user - readable format. we will write a custom capitalise pipe, capitalise, using the standard string. touppercase (). this is only for simplicity as angular has its own uppercasepipe implementation .
pipes are just plain classes that can be injected so we can set up our specs very easily using inject .
in order to test our pipe we checked the common cases: it should work with empty string, it should capitalise and finally that it throws when not used with a string .
routes are sometimes left out but it is usually seen as a good practice for double - entry bookkeeping. in our example, we will use a simple route configuration with only a few routes and an otherwise route pointing to home .
first route definition catches the initial route if none was provided redirecting to home (line 14). the second instantiates the home component (line 15); last one captures all remaining routes and redirects them also to home (line 16). our tests will use these routes to check our expectations out .
we imported routertestingmodule. withroutes (routes) to initialise the router instance with the routes for our tests (line 6). in the code above we tested, we can navigate to home using async, asyncfake / tick and done. notice how we can write a nicer test using asyncfake as we don’t have to nest the promise handling .
observables are great to handle asynchronous tasks. they are used in few places in angular like http, form controls, validations or behind eventemitter. we will use the observable below to show how we can test their behaviour .
we created an observable that emits 1, 2, 3 and completes. in order to test it, we set up the next, error and complete callbacks on subscribe. as next callback will be called few times we have to set our expectations dynamically .
eventemitters are used in angular to communicate events between components. we created a counter component, counter, that allows us to increment or decrement an initial value of zero. each time that we do that the new value will be pushed using an eventemitter exposed as changes .
in this case, we check that we can increment or decrement using subscribe on the eventemitter as it exposes an observable. we trigger the different values by calling the change method and check our expectations within the next callback .
you have all tests included in this post and more on the demo plunker .

: a sample project to load r. u. b. e scenes into chipmunk physics !
: an xcode sample project to load r. u. b. e scenes on ios is now available .
functions which are unique to each test - how the scene should be set up, what mouse / keyboard input should do, etc - can be specified as necessary. before we add a test of our own, let' s take a look at the life - cycle of a test .
the parts in orange are where we will be adding or changing code to make our own test. to be more specific, we will create a subclass of the test class which handles all the common features of a test, and override some functions in our subclass. let' s take a look at some virtual functions in the test class to see what we can use .
the first of these, step () implements the stepping of the physics, and renders the scene. the other three, keyboard (), mousedown () and mouseup () allow us to get some information about what the user is doing. there is no function to override to set up the scene, because this will be done in the constructor of the subclass .
there are also some class member variables accessible from the subclass that will come in handy. these variables which keep track of the main box2d world object which all the other thingies live in, and a body which represents the ground, a very common requirement in many simulations! we' ll look at what a world and a body are a little later .

this example shows a four - wheel drive vehicle with open and limited slip differentials. the front and rear differentials can be standard or type i torsen. the center differential can be a solid shaft, viscous coupling, viscous coupling with a locking clutch, or open with no torque transfer. the differential options are in variant subsystems. the variants can be selected using the hyperlinks embedded in the model .
to test the effect of limited slip differentials, the road surface in the model can be configured such that the tires are on surfaces with varying coefficients of friction. this is configured in the dialog box for the subsystem road .
the plot below shows the results of a four - wheel drive vehicle accelerating from rest with all four wheels on a low friction surface, such as ice. two meters in front of the vehicle starting position is a high friction surface, such as dry tarmac. open differentials are used on the front and rear and a viscous coupling is used on the center differential. as a result, all four wheels slip until all reach a high friction surface .
the plot below shows the results of a four - wheel drive vehicle accelerating from rest with the front wheels on a low friction surface, such as ice, and the front wheels on a high friction surface, such as dry tarmac. the test is run four times with different configurations for the center differential. the shaft connection and the lockup clutch provide the fastest acceleration .
the plot below shows the results of a four - wheel drive vehicle accelerating from rest with the left wheels on a low friction surface, such as ice, and the right wheels on a high friction surface, such as dry tarmac. the test is run twice with different configurations for the front and rear differential. the torsen differential automatically locks under the split surface condition, resulting in faster acceleration .

[ edit ] had a bit more time on my hands and updated testccd and testbridge as well. i' m uploading them now in case i run out of time to work on them tonight. i' ll do the rest and upload when i' m done .
ok, i updated the ragdoll test as well. goes to show the state of the port though... performance is terrible. no offense intended boris, i know you are working on your own and its not done .
do you think you could make this a patch, rather than files? it' s a pain, but it is much easier for me to review changes, and apply. i' m sorry to hear performance is terrible. there' s much inlining to do to re - create the original level, but i suspect the c + + version i' ve ported also has a performance hit .
sure, i didn' t realize it was that easy to create a patch. always finding new reasons to love tortoisesvn. as for the performance, i' m glad to help work on that in any way i can, when i can. i' ve been holding off looking into it at all until 2. 1 was closer to release. now that it is though i will try to find a bit of free time to help out .
committed, thanks! now i look at it there are some problems with the ragdoll example. i think it is a bug in solving continuous physics with joints, rather than general performance issue. i' ll take a look .
my main problem comes from the way fixtures and shapes are now. i did some research into the c + + examples and erin' s comments on those (from his forum post about the big changes .) i have to say i' m a bit confused now. according to what he said, edges are now just polygonshapes with only two vertices... but if everything has a radius now isn' t the radius for those shapes going to be quite large in relation to their thickness? maybe i' m not understanding it quite right .
/ / / create a chain of edges on the provided body. the edge chain does not alter the mass
/ / / of the body, this must be done manually through b2body: : setmassdata .
this in turn calls an internal static function for connection the edges. i notice that in the as3 port this is still part of b2body. as, but the corresponding createedgechain is missing / commented out with a todo. from what i can tell in the c + + code base (haven' t dug really deeply in it, more of a cursory glance ,) edge chains are being created by passing in the def and looping over the vertices to create b2edgedef and eventually a fixture with an edgeshape .
now, i understand what is going on here but i don' t feel comfortable enough to make a decision on where to update it. if you have an idea of what you want though i' m more than happy to finish up. let me know .
perhaps i' m being stupid, but i don' t see this b2createedgechain stuff in the c + +? i' ll port it when i find it. and yes, edges will have a marginal thickness. there are a few other minor short comings, which is what makes me reluctant to discard the old edge stuff quite yet. i' ve just commented out enough to make it compile. i don' t have any plans to fix it up, though, as it' s apparent this is a lot of work. it' s there in case using polygons doesn' t work out .
it is defiined several times in \ trunk \ source \ dynamics \ b2edgechain. h and implemented once in \ trunk \ source \ dynamics \ b2edgechain. cpp wierdly enough the file seems to be in triplicate... didn' t know a beaurocrat wrote it. its not much of a different algorithm than what is currently commented out of the as port. i was more curious where it should go. also, it is referencing b2edgeshapedef and b2edgeshape... which i haven' t looked into to see if its more than a polygon with 2 verts .

honeywell flies a boeing 757 with a difference. the test aircraft is distinguished from an average 757 by a strange outgrowth - a unique extra engine mount. the third engine on the right - hand side of its forward fuselage is used to test the american equipment manufacturer’s various engines .
honeywell uses this flying laboratory to test in - flight business jet engines under development. the jet has been used for research and development by the us company since 2008, and has completed more than 400 flight tests in some 15 countries .
as for the boeing 757’s aerodynamics, these are slightly modified. but according to honeywell, it doesn' t affect the overall handling characteristics of the 757, which has over 1, 700 flying hours under its belt .

farnborough - ge aircraft engines is testing an enhanced ge90 with new technologies to increase on - wing life, fuel burn, and thrust on the boeing 777 .
the ge90' s performance improvement program (pip) will further enhance the engine' s industry - leading fuel burn and payload capability .
pip improvements will provide the ge90 with an exhaust gas temperature (egt) margin enhancement of up to 20 o c, a fuel burn reduction of approximately 1. 7 percent, and the capability to boost thrust up to 93, 000 pounds .
these performance improvements are being achieved through advanced 3 - d aerodynamic design in the compressor and optimized rotor - to - stator clearances in the fan and turbines .
earlier this summer, core engine tests were successfully run at ge' s altitude facility in evendale, ohio. a full ge90 engine was put on test in august at ge' s outdoor test facility at peebles, ohio .
increased customer value is a primary driver in our decision to introduce these new improvements in the engine ,
said chaker chahrour, general manager of ge90 project .
we also have our eye on the engine' s growth potential for the future. testing to date has confirmed realization of our overall objectives .
a prime benefit of the pip - - reduced fuel burn - will provide cost savings from the lower fuel requirement and lower fuel weight, allowing a greater proportion of aircraft takeoff weight to be devoted to increased payload .
the ge90 currently offers roughly a 1. 4 percent advantage in fuel burn compared to competing engines. this ge90 edge translates to savings of up to $ 150, 000 (u. s .) in fuel and up to $ 540, 000 in revenues attributable to increased payload capacity in a typical year' s operation.
