AutoFixture with NUnit AutoMoq prevents tests from running
I am trying to use AutoFixture with NUnit and Moq using the following AutoMoqDataAttribute:
public class AutoMoqDataAttribute : AutoDataAttribute
{
public AutoMoqDataAttribute()
: base(new Fixture().Customize(new AutoMoqCustomization()))
{
}
}
But when I run this test:
[Test, AutoMoqData]
public void Test(Mock<IUser> user)
{
// do stuff with user
}
The test never runs. AutomMoqData hits correctly, but the code inside the test is never executed and everything ends without warning with the following message:
Test adapter sent back a result for an unknown test case. Ignoring result for 'Test(Mock<Sandbox.IUser>)'
The test also does not appear in the list of test runs.
But if I remove the parameter:
[Test, AutoMoqData]
public void Test()
{
// do stuff without user
}
Everything works fine, but it is less useful without passed parameters :)
Did I miss something?
Here is a list of Nuget package versions:
<package id="AutoFixture" version="3.50.2" targetFramework="net452" />
<package id="AutoFixture.AutoMoq" version="3.50.2" targetFramework="net452" />
<package id="AutoFixture.NUnit3" version="3.50.2" targetFramework="net452" />
<package id="Moq" version="4.5.3" targetFramework="net452" />
<package id="NUnit" version="3.7.1" targetFramework="net452" />
EDIT: Following @MarkSeemann's advice, I've filed a bug on Github .

Visual Studio Test Player
This looks like an issue with the NUnit Visual Studio test adapter. I can reproduce the problem when I also add NUnit3TestAdapter to my replication solution.
I also assume that the test class has an attribute [TestFixture]
so that the entire replay class looks like this:
[TestFixture]
public class Tests
{
[Test, AutoMoqData]
public void Test(Mock<IUser> user)
{
Assert.NotNull(user);
}
}
When I try to run all tests with the Visual Studio 2015 test runner, the test never runs and this is the result of checking the output window:
------ Run test started ------
NUnit Adapter 3.7.0.0: Test execution started

========== Run test finished: 0 run (0:00:01,1763498) ==========
TestDriven.Net
If, on the other hand, I try to run it from TestDriven.Net , it works just fine:
------ Test started: Assembly: Ploeh.StackOverflow.Q44564377.dll ------
1 passed, 0 failed, 0 skipped, took 0,79 seconds (NUnit 3.7.1).
TestDriven.Net is sometimes unusually tolerant of small bugs in your test code, so it might not be that in and of itself.
NUnit 3 Console
Since TestDriven.Net may be too liberal in what it takes, the best test would be to try it with the official NUnit 3 console runner :
$ packages/NUnit.ConsoleRunner.3.6.1/tools/nunit3-console.exe 44564377/bin/Debug/Ploeh.StackOverflow.Q44564377.dll
NUnit Console Runner 3.6.1

This also succeeds in the test.
Intermediate withdrawal
Since both the official console runner and TestDriven.Net are running the test successfully, I would tentatively deduce that this looks like a defect in the NUnit3TestAdapter package. May I suggest a problem for you?
