NUnitLite - Explore flag does not apply where filter to output

[chriscore]

Hi there

Running nunit3-console.exe with arguments similar to the following does not apply the filter specified in /where to the results which are seen on the output.

"C:\MyRepo\MyAssembly.dll" /explore /noheader /where="cat==Awesome"

All tests are returned by /explore, including those which do not satisfy cat==Awesome

This was found in NUnit Console Runner v3.0.5813

I was uncertain whether it made sense to use a filter when listing tests, but I suppose it does if you tried it!

Hey Charlie

Thanks, before a test run I am currently trying to call this to see how many tests my filter would return - it would certainly be very useful for me at this point :)

Great work with nunit 3 so far

@chriscore If you have a runner, just call CountTestCases on it with your filter!

If you are simply scripting nunit3-console, that's not an option, of course.

@CharliePoole I don't currently have a runner instance as I haven't been able to figure out how to get that going, like you say I have just scripted nunit3-console, but having that control in process would be ideal.

I did find it difficult to find how to host a runner as there seemed to be a lot of dependent objects which I found difficult to create, do you have a C# snippet anywhere which might give some clues how to start? Being able to load and run tests in process would be ideal for what I'm trying to do here.

Add a reference to nunit.engine.api.dll. Then (simplified)...

ITestEngine engine = TestEngineActivator.CreateInstance();
TestPackage package = new TestPackage(ASSEMBLY_PATH);
ITestRunner runner = engine.GetRunner(package);

This leaves out setting options, using a filter, etc. For the full story, start here:

Thanks so much for that, I didn't know about the TestEngineActivator!

When this is fixed, ensure it also works with NUnitLite. See #1213

I'd also love to see filters working with --explore!
