run-tests.php doesn't create test results if directories are passed

Description

If I execute run-tests.php without arguments, I'm asked if I want to write the test results to a file. This stops working as soon as I limit the tests to some subdirectories by passing them as arguments to run-tests.php. Is there a way to get the test results without running the full test suite?

It probably makes sense to also write the test results to a file even without running all the tests.
In any case, for your CI use case, you can pass --show-diff as an argument to run-tests.php to print out the diff between the expected and actual output.

Thanks, --show-diff is what I was looking for.
