In xUnit I can have a Theory test that uses generics in this form: [Theory] [MemberData(SomeScenario)] public void TestMethod<T>(T myType) { Assert.Equal(typeof(double), typeof(T)); } public static IEnumerable<object[]> SomeScenario() { yield return new object[] { 1.23D }; } Which will give me the generic T parameter as double . Is it possible to use MemberData to specify the generic type parameter for a test with a signature like: [Theory] [MemberData(SomeTypeScenario)] public void TestMethod<T>() { Assert.Equal(typeof(double), typeof(T)); } If it is not possible with MemberData or any other

I’m using xUnit, SubSpec and FakeItEasy for my unit tests. I’ve so far created some positive unit tests like the following: "Given a Options presenter" .Context(() => presenter = new OptionsPresenter(view, A<IOptionsModel>.Ignored, service)); "with the Initialize method called to retrieve the option values" .Do(() => presenter.Initialize()); "expect the view not to be null" .Observation(() => Assert.NotNull(view)); "expect the view AutoSave property to be true" .Observation(() => Assert.True(view.AutoSave)); But now I want to write some negative unit tests and check that certain methods don't

I'm trying to setup my tests using Xunit. I have a requirement to delete all images in a folder start of the tests, and then each method does some image resizing and saves a copy of it's output to the folder. The folder should only be emptied once, and then each method will save their own image into the folder. When I use IUseFixture<T> , the ClearVisualTestResultFolder function is still being called before every test, so I only end up with one image in the folder. public class Fixture { public void Setup() { ImageHelperTest.ClearVisualTestResultFolder(); } } public class ImageHelperTest :

Context in XUnit github I found this: Add Assert.Equal(expected, actual, message) overload #350 (so a developer ask for a non existing overload see below) Quote from the answer: We are a believer in self-documenting code; that includes your assertions. (so the XUnit team rejects it) OK, I got it. I also believe the self documenting code. Still I can not find out this use case: Sample // Arrange // Create some external soap service client and its wrapper classes // Act // client.SomeMethod(); // Assert // Sorry, soap service's interface, behaviour and design is *given* // So I have to check if

I have in my test suite a test that goes something like this: [Fact] public void VerifySomeStuff() { var stuffCollection = GetSomeStuff(); Assert.Equal(1, stuffCollection.Count()); } This test works as I expect, but when I run it xUnit prints a warning: warning xUnit2013: Do not use Assert.Equal() to check for collection size. However, no alternative is suggested in the warning, and a google search takes me to the source code in xUnit for the test that verifies this warning is printed. If Assert.Equal() isn't the correct way to verify the lenght of a collection, what is? To clarify: I realize

I added a post-build action : "Publish xUnit test result report" Then, in this post-build step I added : "BoostTest-1.x (default)" Now I have the following options to set: https://www.dropbox.com/s/wxcny55rz2bqk6r/boost_jenkins_options.png The options I set are random, so please help me, I don't understand anything and I didn't find some tutorials. I have not worked with boost unit test and not with the xUnit Jenkins plugin
