  • Any special assertion to test if the resulting integer lies within a range

    - by barerd
    I would like to test if an instance variable lies in a range of numbers. I solved the problem by using assert_in_delta but would like to know if there is a formal assertion for this. #part of the tested class def initialize(value = 70 + rand(30)) @value = value end #test_value.rb class ValueTestCase < Test::Unit::TestCase def test_if_value_in_range assert_in_delta(85, p.value, 15) end end

  • Run PHPUnit Tests in Certain Order

    - by dragonmantank
    Is there a way to get the tests inside of a TestCase to run in a certain order? For example, I want to seperate the lifecycle of an object from creation to use to destruction but need to make sure that the object is set up first before I run the other tests.

  • Mocking imported modules in Python

    - by Evgenyt
    I'm trying to implement unit tests for function that uses imported external objects. For example helpers.py is: import os import pylons def some_func(arg): ... var1 = os.path.exist(...) var2 = os.path.getmtime(...) var3 = pylons.request.environ['HTTP_HOST'] ... So when I'm creating unit test for it I do some mocking (minimock in my case) and replacing references to pylons.request and os.path: import helpers def test_some_func(): helpers.pylons.request = minimock.Mock("pylons.request") helpers.pylons.request.environ = { 'HTTP_HOST': "localhost" } helpers.os.path = minimock.Mock(....) ... some_func(...) # assert ... This does not look good for me. Is there any other better way or strategy to substitute imported function/objects in Python?

  • Spring MVC with several configurations

    - by Michael Bulla
    Hello, for my spring-mvc application I created several types of configuration (unittest, integration, qa, production). All the configs are in one war-file, so there is only one type of application I create. Which configuration to take should be decided by the server, where the application is running. To decide what kind of configuration should be used, I have to look into a file. After that I can decide which configuration should be used by spring mvc. For now by convention there is always the -servlet.xml used. Is there a way how to decide dynamically which config to take? Regards, Michael

  • Error using MVCContrib TestHelper

    - by Brian McCord
    While trying to implement the second answer to a previous question, I am receiving an error. I have implemented the methods just as the post shows, and the first three work properly. The fourth one (HomeController_Delete_Action_Handler_Should_Redirect_If_Model_Successfully_Delete) gives this error: Could not find a parameter named 'controller' in the result's Values collection. If I change the code to: actual .AssertActionRedirect() .ToAction("Index"); it works properly, but I don't like the "magic string" in there and prefer to use the lambda method that the other poster used. My controller method looks like this: [HttpPost] public ActionResult Delete(State model) { try { if( model == null ) { return View( model ); } _stateService.Delete( model ); return RedirectToAction("Index"); } catch { return View( model ); } } What am I doing wrong?

  • defining a simple implicit Arbitary

    - by FredOverflow
    I have a type Foo with a constructor that takes an Int. How do I define an implicit Arbitrary for Foo to be used with scalacheck? implicit def arbFoo: Arbitrary[Foo] = ??? I came up with the following solution, but it's a bit too "manual" and low-level for my taste: val fooGen = for (i <- Gen.choose(Int.MinValue, Int.MaxValue)) yield new Foo(i) implicit def arbFoo: Arbitrary[Foo] = Arbitrary(fooGen) Ideally, I would want a higher-order function where I just have to plug in an Int => Foo function. I managed to cut it down to: implicit def arbFoo = Arbitrary(Gen.resultOf((i: Int) => new Foo(i))) But I still feel like there has got to be a slightly simpler way.

  • Reflection in unit tests for checking code coverage

    - by Gary
    Here's the scenario. I have VO (Value Objects) or DTO objects that are just containers for data. When I take those and split them apart for saving into a DB that (for lots of reasons) doesn't map to the VO's elegantly, I want to test to see if each field is successfully being created in the database and successfully read back in to rebuild the VO. Is there a way I can test that my tests cover every field in the VO? I had an idea about using reflection to iterate through the fields of the VO's as part of the solution, but maybe you guys have solved the problem before? I want this test to fail when I add fields in the VO, and don't remember to add checks for it in my tests.

  • Rhino Mocks - Do we really need stubs?

    - by Marcelo Oliveira
    If it's possible to change mock behaviour in Rhino Mocks using mock.Stub().Return(), why do we need Stubs anyway? What do we lose by always using MockRepository.GenerateMock()? One big benefit of using Mocks instead of Stubs is that we will be able to reuse the same instance among all the tests keeping them cleaner and straightforward. The moq framework works in a similar way... we don't have different objects for mocks and stubs. (please, don't answer with a link to Fowler's "Mocks aren't stubs" article)

  • MS Access 2007 - Property for text box to allow end-user to hit enter for return, not next

    - by Justin
    So I have a form that user's use for data entry, and on one form there is a text box there that is basically used. To enter notes. However, if the user hits i need the cursor to stay in that text box, and start a new line (uh....like word would)....but currently it is jumping to the next control (text box). So is there a simple property setting that would do the trick? Or a VBA method to accomplish? Thanks Justin

  • Is Assert.Fail() considered bad practice?

    - by Mendelt
    I use Assert.Fail a lot when doing TDD. I'm usually working on one test at a time but when I get ideas for things I want to implement later I quickly write an empty test where the name of the test method indicates what I want to implement as sort of a todo-list. To make sure I don't forget I put an Assert.Fail() in the body. When trying out xUnit.Net I found they hadn't implemented Assert.Fail. Of course you can always Assert.IsTrue(false) but this doesn't communicate my intention as well. I got the impression Assert.Fail wasn't implemented on purpose. Is this considered bad practice? If so why? @Martin Meredith That's not exactly what I do. I do write a test first and then implement code to make it work. Usually I think of several tests at once. Or I think about a test to write when I'm working on something else. That's when I write an empty failing test to remember. By the time I get to writing the test I neatly work test-first. @Jimmeh That looks like a good idea. Ignored tests don't fail but they still show up in a separate list. Have to try that out. @Matt Howells Great Idea. NotImplementedException communicates intention better than assert.Fail() in this case @Mitch Wheat That's what I was looking for. It seems it was left out to prevent it being abused in another way I abuse it.

  • Running single test class or group with Surefire and TestNG

    - by Slartibartfast
    I want to run single test class from command line using Maven and TestNG Things that doesn't work: mvn -Dtest=ClassName test I have defined groups in pom.xml, and this class isn't in one of those groups. So it got excluded on those grounds. mvn -Dgroups=skipped-group test mvn -Dsurefire.groups=skipped-group test when config is <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-surefire-plugin</artifactId> <version>2.7.1</version> <configuration> <groups>functest</groups> </configuration> </plugin> Parameters work fine in there are no groups defined in pom.xml. Similarly, when surefire is configured with <configuration> <includes> <include>**/*UnitTest.java</include> </includes> </configuration> I can add another test with -Dtest parameter, but cannot add group. In any combination, I can narrow down tests to be executed with groups, but not expand them. What's wrong with my configuration? Is there a way to run a single test or group outside of those defined in pom.xml? Tried on Ubuntu 10.04 with Maven 2.2.1, TestNG 5.14.6 and Surefire 2.7.1

  • Texture not rendering in correct order in xna 4?

    - by user1090751
    I am making a simple board game. In the game there is a fixed background called myTexture and others are textureGoat and textureTiger whicha are to be placed on top of the background(myTexture). But i am having problem that fourth and fifth component is not displaying however, the sixth component( i.e. myTexture) is appearing. Here is my code, please look at it protected override void Draw(GameTime gameTime) { GraphicsDevice.Clear(Color.Green); // TODO: Add your drawing code here spriteBatch.Begin(SpriteSortMode.BackToFront, BlendState.AlphaBlend); //placing tiger spriteBatch.Draw(textureTiger, new Rectangle(22, 25, 50, 50), Color.White);//first component spriteBatch.Draw(textureTiger, new Rectangle(22, 407, 50, 50), Color.White);//second component spriteBatch.Draw(textureTiger, new Rectangle(422, 25, 50, 50), Color.White);//third component spriteBatch.Draw(textureTiger, new Rectangle(422, 407, 50, 50), Color.White);//fourth component //placing goat spriteBatch.Draw(textureGoat, new Rectangle(125, 110, 50, 50), Color.White);//fifth component //placing background spriteBatch.Draw(myTexture, new Rectangle(0, 0, 500, 500), Color.White);//sixth component spriteBatch.End(); base.Draw(gameTime); }

  • Mock a void method which change the input value

    - by Kar
    Hi, How could I mock a void method with parameters and change the value parameters? My void method looks like this: public interface IFoo { void GetValue(int x, object y) // takes x and do something then access another class to get the value of y } I prepared a delegate class: private delegate void GetValueDelegate(int x, object y); private void GetValue(int x, object y) { // process x // prepare a new object obj if (y == null) y = new Object(); if (//some checks) y = obj; } I wrote something like this: Expect.Call(delegate {x.GetValue(5, null);}).Do (new GetValueDelegate(GetValue)).IgnoreArguments().Repeat.Any(); But seems like it's not working. Any clue on what could be wrong?

  • Caching result of setUp() using Python unittest

    - by dbr
    I currently have a unittest.TestCase that looks like.. class test_appletrailer(unittest.TestCase): def setup(self): self.all_trailers = Trailers(res = "720", verbose = True) def test_has_trailers(self): self.failUnless(len(self.all_trailers) > 1) # ..more tests.. This works fine, but the Trailers() call takes about 2 seconds to run.. Given that setUp() is called before each test is run, the tests now take almost 10 seconds to run (with only 3 test functions) What is the correct way of caching the self.all_trailers variable between tests? Removing the setUp function, and doing.. class test_appletrailer(unittest.TestCase): all_trailers = Trailers(res = "720", verbose = True) ..works, but then it claims "Ran 3 tests in 0.000s" which is incorrect.. The only other way I could think of is to have a cache_trailers global variable (which works correctly, but is rather horrible): cache_trailers = None class test_appletrailer(unittest.TestCase): def setUp(self): global cache_trailers if cache_trailers is None: cache_trailers = self.all_trailers = all_trailers = Trailers(res = "720", verbose = True) else: self.all_trailers = cache_trailers

  • Grails 1.3.3: controller.redirectArgs.action not populated

    Does anyone knows what happened to controller.redirectArgs.action in the latest version of Grails (1.3.3)? It used to work properly but now I get NPE when I use it. class FooController { def someRedirect = { redirect(action:"bar") } } class FooControllerTests extends grails.test.ControllerUnitTestCase { void testSomeRedirect() { controller.someRedirect() assertEquals "bar", controller.redirectArgs.action } } In this case controller.redirectArgs is already null...

  • How can I unit test a PHP class method that executes a command-line program?

    - by acoulton
    For a PHP application I'm developing, I need to read the current git revision SHA which of course I can get easily by using shell_exec or backticks to execute the git command line client. I have obviously put this call into a method of its very own, so that I can easily isolate and mock this for the rest of my unit tests. So my class looks a bit like this: class Task_Bundle { public function execute() { // Do things $revision = $this->git_sha(); // Do more things } protected function git_sha() { return `git rev-parse --short HEAD`; } } Of course, although I can test most of the class by mocking git_sha, I'm struggling to see how to test the actual git_sha() method because I don't see a way to create a known state for it. I don't think there's any real value in a unit test that also calls git rev-parse to compare the results? I was wondering about at least asserting that the command had been run, but I can't see any way to get a history of shell commands executed by PHP - even if I specify that PHP should use BASH rather than SH the history list comes up empty, I presume because the separate backticks executions are separate terminal sessions. I'd love to hear any suggestions for how I might test this, or is it OK to just leave that method untested and be careful with it when the app is being maintained in future?

  • ReSharper no longer runs unit tests

    - by Ed Woodcock
    Hey folks I'm trying to write some unit tests for an app I work on at work (In the vague hope that others might follow suit), and I was originally running these tests using NUnit and the ReSharper plugin. However, ReSharper will no longer run tests for me for some reason: It simply crosses them out with a red strikeout. There's no error code I'm afraid, and there's no mention of such behaviour on the JetBrains site. Has anyone else experienced similar benhaviour? Cheers, Ed
