TUI for pytest-xdist

[cool-RR]

I use pytest-xdist a lot to run my tests on parallel processes. I really wish there was a great TUI for it. One thing that's frustrating is that I have no convenient way to see which tests passed and which failed. While pytest does output that, it's basically spewing that output in random order in my shell. I have no way to ask "Did this test pass or not?" "Which tests are currently run?" "How many of the tests are left?" or even "show me the exception from this test that failed while pytest-xdist is still running the other tests."

If anyone has the motivation to write such a TUI, that will be most helpful. If you have other solutions to these problems, I'll be happy to hear them.

verbose mode -vv shows [workerID] test_name PASS/FAIL. isnt it what you looking for?

No. It's a garden hose of text. When you have hundreds of tests it's unmanagable. Things I can't easily do:

1. Search whether a certain test failed or passed.
2. See the traceback for a test that failed without waiting for the test run to finish.
3. Search whether a certain test started to run.
4. Tell pytest-xdist to run a certain test next time a worker is available.
5. Lots of other stuff that would probably be way easier in a TUI.

A TUI for pytest/pytest-xdist sure does sound interesting.

There are projects which supply alternative terminal output:

• pytest-sugar
• pytest-rich
• pytest-modern

None of them however provide a TUI.

Such TUI can and should be developed outside pytest-xdist itself. If somebody does, we would be happy to add a link to it in the pytest-xdist documentation.

Thank you. Do you know whether any of these work well with pytest-xdist multiprocessing?

[cool-RR]

Eh, looks like pytest-sugar doesn't, and the two others are less developed. Thanks anyway.
