  • Which jsPerf-test should I consider as standard for checking the performance of javascript template-engines

    - by bhargav
    I am on a search for a javascript template engine that has good performance when used in large js applications and is also very suitable for mobile applications. So I have gone through the various jsPerf-tests for these. There seems to be a lot which show different results and it is confusing to find out which is the standard test. Can some one guide me a standard jsPerf that I can refer to and that should also include following templates dust, underscore, hogan, mustache, handlebars. From what I have observed dot.js is a constant performer with good rendering speed, but is it mature enough for larger applications ? What is this "with" and "no with" that is shown in the jspref tests? Can some one explain. In all the tests I have seen popular templates like mustache, handlebars, dust, hogan,etc seems to be behind performance than other templates, so why people are using them leaving out the top performers,is it because of maturity of these template engines? Thanks in advance

  • disabling transactional fixtures in Rspec has no effect

    - by Dia
    Due to a legacy database I'm using, I'm stuck with MySQL using MyISAM, which means my tables don't support transactions. This is causing the tests to fail, since table data generated (I'm using factory_girl for fixtures) by the tests are not reverted for each scenario. I discovered that Rspec exposes the config.use_transactional_fixtures config setting in spec_helper.rb. which is set to true by default. When I set it to false, I don't see any effect on my tests; they still fail due to duplicate records. Isn't that setting supposed to automatically unroll any changes made to the DB? Or am I supposed to do that manually?

  • How do I add a VSTO project as a reference to a unit testing project?

    - by Mathias
    In order not to pollute my projects with unit tests, I like to create a separate project for my unit tests; I add a reference to the project under test in the unit tests project. However, this isn't working that well with my VSTO excel add-in projects: when I create a separate unit test project and go to Add Reference Projects, there is no project to pick. What I have done so far is Add Reference Browse, and pick the add-in dll from the debug folder. I have also run into issues from time to time with this, with the reference suddenly not working, requiring to remove/re-add the dll reference. Can anybody explain why a VSTO project doesn't show up as a regular project? And is there a better way to go about it than what I am doing presently?

  • Get ANSI-colored output from external command

    - by German Rumm
    I am writing a small script for watchr that runs my PHP unit tests. Current script runs tests using system() and displays them colored. I am trying to add libnotify functionality, but for that I need to parse the output and match against regexp, so that notification will either display green or red. system() doesn't return output, %x does return, but puts p doesn't display colors, which I need to quickly see which test failed. One option would be to run tests twice - once for display in terminal window, and second time for checking which notification to show, but I would rather avoid it.

  • How can I include utility functions from another file into a Sproutcore unit test file?

    - by Lauri
    Lets say I have a few utility functions in file tests/utils/functions.js. I would like to use these functions from several unit test files. However, I'm not able to use them as the Sproutcore build system does not include any external files into the html page used to run the unit tests. Only application code and the code from the unit tests to be run are included. So is it possible to somehow include Javascript files to be used in unit test files in Sproutcore? I could add the functions.js file into some other directory inside my application to be able to use them. However, this is not what I want to do as the utility functions are useless in final production build and would only make my application larger.

  • How to make django test framework read from live database?

    - by lfborjas
    I realize there's a similar question here, but this one has a different approach: I have a django app that does queries over data indexed with djapian ; I'd like to write unit tests for this app's search component, and, obviously, I'd need the django settings module and all connections with the database active, so the test runner that django provides seems ideal. however, the django testing framework creates a dummy database and I'd hate to dump all my data to a fixture and then index it (the tests would take forever!); My data isn't at risk because the tests would only read from the database, so, how could this be achieved? -I'm new at this whole unit testing thing, so the solution of writing a new test runner I read in that similar question doesn't enlighten me a bit, at least not without some details

  • How to run a recorded (HTML) selenium test from .NET

    - by Gaspar Nagy
    I run Selenium tests with Selenium RC from .NET (c#). In some cases, I would like to keep the test case source as HTML (to be able to modify it from Selenium IDE), but I would like to run/include these tests from my c# unit tests. Maybe it is obvious, but I can't find the API method in the Selenium Core to achieve this. Any idea how to do that? (I think the "includePartial" command in Selenium on Rails does the thing that I would need, but for c#.)

  • How do we name test methods where we are checking for more than one condition?

    - by Sandbox
    I follow the technique specified in Roy Osherove's The Art Of Unit Testing book while naming test methods - MethodName_Scenario_Expectation. It suits perfectly well for my 'unit' tests. But,for tests that I write in 'controller' or 'coordinator' class, there isn't necessarily a method which I want to test. For these tests, I generate multiple conditions which make up one scenario and then I verify the expectation. For example, I may set some properties on different instances, generate an event and then verify that my expectation from controller/coordinator is being met. Now, my controller handles events using a private event handler. Here my scenario is that, I set some properties, say 3 condition1,condition2 and condition3 Also, my scenario includes an event is raised I don't have a method name as my event handler is private. How do I name such a test method?

  • Maven2 junit timeout annotation doesn't work

    - by roesslerj
    We have a bunch of tests in a maven2 project and build with cruisecontrol. However the build regularly hangs, because the annotation of the test with a timeout @Test(timeout = 5000) is ignored. I tried and run maven locally, reproducing the fact, that the timeout is ignored. Is there a way to activate the timeout for the tests again? I currently use a work arround in setting a timeout in cruisecontrol. However this simply means that the whole build is chancelled, and not just the tests that should fail. Remark: It seems in maven 1 there was a property to activate the junit timeout which is missing in maven 2.

  • Rails fixtures seem to be adding extra unexpected data

    - by Mason Jones
    Hello, all. I've got a dynamic fixture CSV file that's generating predictable data for a table in order for my unit tests to do their thing. It's working as expected and filling the table with the data, but when I check the table after the tests run, I'm seeing a number of additional rows of "blank" data (all zeros, etc). Those aren't being created by the fixture, and the unit tests are read-only, just doing selects, so I can't blame the code. There doesn't seem to be any logging done during the fixtures setup, so I can't see when the "blank" data is being inserted. Anyone ever run across this before, or have any ideas of how to log or otherwise see what the fixture setup is doing in order to trace down the source of the blank data?

  • Is there a difference between `==` and `is` in python?

    - by Bernard
    My Google-fu has failed me. In Python, are these: n = 5 # Test one. if n == 5: print 'Yay!' # Test two. if n is 5: print 'Yay!' two tests for equality equivalent (ha!)? Does this hold true for objects where you would be comparing instances (a list say)? Okay, so this kind of answers my question: l = list() l.append(1) if l == [1]: print 'Yay!' # Holds true, but... if l is [1]: print 'Yay!' # Doesn't. So == tests value where is tests to see if they are the same object?

  • What technologies to use for a particle system with enormous calculation demand?

    - by Amir Rezaei
    I have a particle system with X particles. Each particle tests for collision with other particles. This gives X*X = X^2 collision tests per frame. For 60f/s, this corresponds to 60*X^2 collision detection per second. What is the best technological approach for these intensive calculations? Should I use F#, C, C++ or C#, or something else? The following are constraints The code is written in C# with the latest XNA Multi-threaded may be considered No special algorithm that tests the collision with the nearest neighbors or that reduces the problem The last constraint may be strange, so let me explain. Regardless constraint 3, given a problem with enormous computational requirement what would be the best approach to solve the problem. An algorithm reduces the problem; still the same algorithm may behave different depending on technology. Consider pros and cons of CLR vs native C.

  • Unit testing task queues in AppEngine

    - by Swizec Teller
    For a very long time now I've been using task queues on AppEngine to schedule tasks, just the way I'm supposed to. But what I've always been wondering is how does one write tests for that? Until now I've simply made tests to make sure an error doesn't occur on the API that queues a task and then wrote the more proper tests for the API executing the task. However lately I've started feeling a bit unsatisfied by this and I'm searching for a way to actually test that the correct task has been added to the correct queue. Hopefully this can be done better than simply by deploying the code and hoping for the best. I'm using django-nonrel, if that has any bearing on the answer. To recap: How can a unit test be written to confirm tasks have been queued?

  • Grails unit testing and bootstrap

    - by tbruyelle
    I wrote an unit test for a controller. I have a Bootstrap file which alter the metaclass of domain classes by adding a method asPublicMap(). I use this method in the controller to return domain classes as json but only some selected public fields. My unit test failed because of MissingMethodException for asPublicMap(). As I understood, bootstrap classes are not loaded for unit tests, only for integration tests. That's why I got this error. My question is : Is there another place to put metaclass manipulation in order to take them into account during unit tests ?

  • Distributing requests to Selenium Grid RC's?

    - by intervigil
    I've got a situation here where I have a central selenium grid hub, and several RC's running on my gogrid account. When I access it to run tests, it basically queues all the incoming test requests and executes them serially on only one of the RC's, instead of spreading them out to use available RC's. The tests come from multiple projects, so I'm not looking to parallelize the tests themselves, just to split the requests that come from multiple projects across the multiple RC's. From everything I've read, it seems like selenium grid should be doing this already, yet I only see one RC used to run every single test. Is there something I'm missing?

  • Best practices to test protected methods with PHPUnit

    - by GrGr
    Hello, I found the discussion on Do you test private method informative. I have decided, that in some classes, I want to have protected methods, but test them. Some of these methods are static and short. Because most of the public methods make use of them, I will probably be able to safely remove the tests later. But for starting with a TDD approach and avoid debugging, I really want to test them. I thought of the following: Method Object as adviced in an answer seems to be overkill for this. Start with public methods and when code coverage is given by higher level tests, turn them protected and remove the tests. Inherit a class with a testable interface making protected methods public Which is best practice? Is there anything else? It seems, that JUnit automatically changes protected methods to be public, but I did not have a deeper look at it. PHP does not allow this via reflection.

  • Can I accesss an external file when testing an R package?

    - by Abe
    I am using the testthat package to test an R package that is within a larger repository. I would like to test the contents of a file outside of the R package. Can I reference a file that is located outside of an R package while testing? What I have tried A reproducible example can be downloaded as MyRepo.tar.gz My repository is called "myRepo", and it includes an R package, "myRpkg" and a folder full of miscellaneous scripts ~/MyRepo/ ~/MyRepo/MyRpkg ~/MyRepo/Scripts The tests in "MyRpkg" are in the /tests/ folder ~/myRepo/myRpkg/tests/test.myscript.R And I want to be able to test a file in the Scripts folder: ~/MyRepo/Scripts/myscript.sh I would like to read the script to test the contents of the first line doing something like this: check.script <- readLines("../../../Scripts/myscript.sh")[1] expect_true(grepl("echo", check.script)) This works fine if I start from the MyRepo directory: cd ~/MyRepo R CMD check MyRpkg But if I move to another directory, it fails: cd R CMD check MyRepo/MyRpkg

  • Running Test framework as part of application

    - by VP
    Hi, I would like to know if it is possible in rails to run some test cases through my application. I mean, i want show the test results to users. So i was thinking to be able to call my tests through a controller and put the tests output in a dialog. Imagine that i'm doing an application where before to apply a rule, i want to run some validation tests. I could write methods in my rule model to do it, but i would like to use something like shoulda or any other kind of DSL where the "fixture" would be a record itself. Any tip or idea?

  • Ways to Unit Test Oauth for different services in ruby?

    - by viatropos
    Are there any best practices in writing unit tests when 90% of the time I'm building the Oauth connecting class, I need to actually be logging into the remote service? I am building a rubygem that logs in to Twitter/Google/MySpace, etc., and the hardest part is making sure I have the settings right for that particular provider, and I would like to write tests for that. Is there a recommended way to do that? If I did mocks or stubs, I'd still have to spend that 90% of the time figuring out how to use the service, and would end up writing tests after the fact instead of before...

  • Uninstall or Disable Dell Wave

    - by Onion-Knight
    The image we put on our company laptops includes the Dell Wave interface for Biometric log in. The Wave UI increases boot time by about 5 minutes (because it loads the fingerprint database(a feature I don't use)), so I'm trying to uninstall it, but with little success. There is no line-item in the Add/Remove Programs menu to formally delete it, nor is there a Service I can stop/remove to disable the Wave UI. I've tried looking online, but all I find instead are hits for Google Wave and virus-removal forums with HyjackThis dumps that include Dell Wave records. Any ideas? Edit: Removal isn't entirely necessary. Disabling the Wave UI is good enough.
