Cannot load quickfixlist with tests results

[eruizc-dev]

TLDR:

The way failed tests are notified makes it hard to load them into quickfixlist.

Description

I use vim-dispatch to run tests, which runs a makefile and loads output to quickfixlist. The problem is that Plenary seems to prepend 3 dots (...) to long paths creating a non-valid path for quickfixlist to follow.

As you can see in the following quickfixlist, it's filled with invalid paths and noise

• Resulting quickfixlist:

• This is my makefile:

  test:
  nvim --headless -c "PlenaryBustedDirectory ."

It may be related to issue https://github.com/nvim-lua/plenary.nvim/issues/73, but one is for human readability and this one is for parsing

Repro steps

1. Install plenary.nvim and vim-dispatch
2. Create a lua project with a makefile like the previously mentioned (or you can also clone mine)
3. Run :Make command
4. See the resulting quickfixlist with :copen

We should add a different output format maybe that is JSON or something and you could just put in qflist programmatically
