I think I didn't express myself well. I meant to say that gtest's CLI doesn't
have a flag to allow passing parameters to tests, meaning that it would not be
possible to parametrize the tests from the command line and also remove our
own parser and rely on gtest's.
But gtest does allow test parametrization at runtime and I'm already relying on
it since v2. Let me go a bit more over the way I'm doing this.
- I have a test defined, eg BalancedSingleCycle, which takes some parameters:
std::shared_ptr<Camera> camera, StreamRole role, unsigned int numRequests
- Since we may want to run the same test for all cameras, roles and numRequests,
I register it, at runtime, using my REGISTER_TESTS() macro, which calls
gtest's testing::RegisterTest() with all possible combinations of parameters.
- Based on the --gtest_filter CLI argument from gtest, it decides which tests
are actually run
So the key point is that even though I parametrize the tests, I do it for all
combinations in order to later rely on gtest_filter to select which tests to
run.
Now, I do agree with both of your points. And if we want to make the interface
more intuitive to use (which I also find important), there's no way around
having our own parser.
And if we're using our own camera flag, then it makes no sense to register tests
for all cameras, we can register tests only with the specified camera.
I think here it would be helpful to think if the interface suits our problem.
To me we're looking at having:
lc-compliance --camera 'cameraId' --filter 'BalancedSingleCycle'
to only test camera 'cameraId' with a single test 'BalancedSingleCycle'. Here,
the camera flag is used to only register tests with that camera, and the filter
is passed as --gtest_filter, possibly a bit adapted, to gtest.
And if we imagine we have a test ConcurrentCameras, which receives two cameras
as parameters, and we call
lc-compliance --camera 'cameraId1,cameraId2'
it would test both each of the cameras separately in all current tests which
accept a single camera, like BalancedSingleCycle, as well as test both at the
same time in the ConcurrentCameras test (and we could make only the former or
the latter occur by using the filter parameter).
I know we don't need to implement support for multiple cameras right now, I just
want to make sure it's possible and thinking about the interface and the
scenarios help me picture how they'd work.
Thoughts?
Thanks,
