abort test before any failure detected

always

What is the expected behavior? Why is that the expected behavior?

test aborted

What do you see instead?

all tests passed

Additional information

During run tools/test.py "All tests passed." is printed even when the user aborted the test using the keyboard (e.g., Ctrl+C), as long as no test failures had occurred.

This can be confusing. I hope that different output would be printed.
