This is quite simple but annoying behaviour I am running into with NUnit:
I have some tests like this:
[Test] [TestCase( 1, 2, "hello" )] [TestCase( 3, 5, "goodbye" )] public void MyClass_MyMethod( int a, int b, string c ) { Assert.IsTrue( a < b ); }
This works fine and in the ReSharper NUnit pane I can see each TestCase getting its own response in the result.
I have a second TestCase that looks like this:
[Test] [TestCase( 1, 2, new long[] { 100, 200 })] [TestCase( 5, 3, new long[] { 300, 500 })] public void MyClass_MyOtherMethod( long a, long b, long[] bunchOfNumbers ) { Assert.IsTrue( a < b ); }
When I run it I see this:
One or more child tests had errors Exception doesn't have a stacktrace
public void MyClass_MyOtherMethod(5,3,System.Int64[]) failed
The difference being that with my other tests it draws out each TestCase as a separate checkbox on the test list, whereas this one does not get shown and I have no detail until I run it in a debugger as to what went wrong and where. I am a little concerned about how this test will behave on the build machine. Does anyone have any idea what is going on and why?
Following on from this bug at JetBrains it looks as though the solution here is to use the TestName
attribute on your different cases:
[Test] [TestCase( 1, 2, new long[] { 100, 200 }, TestName="Test 1" )] [TestCase( 5, 3, new long[] { 300, 500 }, TestName="Test 2" )] public void MyClass_MyOtherMethod( long a, long b, long[] bunchOfNumbers ) { Assert.IsTrue( a < b ); }
Everything now shows correctly in ReSharper if one of my tests fails.
