Re-run only failed tests about alchemist.el HOT 7 OPEN

I just saw this and thought mix test --stale might cover it but it doesn't. With ExUnit you can do

mix test --only line:99 --only line:123 test/foo_test.exs --only line:10 test/bar_test.exs

So it should be possible to parse the output and transform it into a command line that just runs the failed tests. Probably a bit harder than rspec though as it does output a list of the failed tests at the end.

Yeah thats a good idea. :)

This is a great idea!

We already talked with Jose about that, because we need to update ExUnit itself for that. Currently there isn't support to run multiple files and locations like mix test one_test.exs:10 two_test.exs.25.

I will infesting some time into it in the next few days If I get some free time.

Thanks

@tonini ping.

Have something changed in this regard? If yes I would like to attack this issue

Hi @rranelli

Thanks for getting back to this issue.

Currently we have alchemist-mix-rerun-last-test, as the name of the function already says it just runs your last test run.

But to implement a function which just runs the latest failed tests we need to extend ExUnit by itself. Jose already mentioned that it would be welcome if someone add multiple mix file:12 file_2:33 functionality to ExUnit.

So I guess the best start would be if you beginning on the ExUnit side and after that you're welcome to add the functionality to Alchemist 👍

Looks like it is possible to solve this issue now :)

I will try to take a look at this sometime in the near future. Thanks for the finding @chrismcg o/
