Provide a way to re run changed tests only

Description

Hi,

When the test suite is huge and takes time to run, there is no way to my knowledge to run only the test I am working on.

I either keep it broken with something like assertTrue(false) at the end of the test, coupled with broken-only mode, but this is ugly and only practical when there is just one broken test (it does not work when making big changes that will break things). Otherwise, as soon as the test is green, it will not be ran again in broken-only mode, and running all the tests is not an option when that is slow.

What do you think?

Implementation ideas

I have no idea of how the state is kept for broken tests, but I guess that state could also keep the last time the test ran, to be compared to the compilation time when the file is changed.

Oh I totally missed this configuration property.

Well that covers my needs. From my point of view this issue can be closed if you are not interested by a “changed tests” mode.

Thank you!

Thanks for your feedback!

I’m closing this because cont testing already detects which tests are changed/affected.
