Question

Separately from the above is there a way to force Pants to run tests in a particular order e g I m running tests in a particular folder which has 3 `test lt xxx gt py` files and my tests fail depending on the order in which Pants decides to run the files so making it a bit time consuming to force a run that triggers the race condition

Ouch I m not aware of any way to order the test runs But I d feel like there s something fishy with the tests when there are dependencies of this kind between tests

Oh I agree that there is Just trying to debug it Would be helpful if I got debug output from within the fixtures and the successful tests but alas I m not getting any at the moment

All good I have a way to make my asserts more forgiving

But to explain a bit more about my context I m running all the tests in a directory package This contains three modules `A` `S` and `Q` So there are six combinations `ASQ` `AQS` `SAQ` `SQA` `QAS` `QSA` I think if `S` runs before `Q` then that is the cause of the problem but I m not 100 sure if both `SAQ` and `ASQ` are misbehaving as its time consuming to force both of these to appear randomly

Add to that a shared database that should be being cleared between each test and a package level fixture then there s a lot going on sweat smile

But the ability to force the order would be useful so that I can fully understand what is going on

Hmm I wonder if running the pytest sessions interactively will force them to be run sequentially in a defined order as provided on the cmd line for instance ` pants test debug A S Q`

What about using Andreas s suggestion of sequential interactive runs instead of pytest s parallel running + something like Also not sure if re naming your files is a possibility I can t recall how pytest enumerates files by default but maybe there is something you could do to change the ordering via config Or force the ordering

rapid-exabyte-76685 · Answer

I ll give these a go I am running with ` process execution local parallelism=1` anyway

yeah ` pants test debug` makes things run sequentially I m not certain the ordering is stable but we could make it be probably
