PlenaryBustedDirectory hangs when run from existing NeoVim instance

[smackesey]

I can run plenary tests from the command line. For instance, I have a project ifactor with one test file in test/ifactor_spec.lua. This works:

$ cd /path/to/ifactor/root
$ nvim --headless -c "PlenaryBustedDirectory test {minimal=true}"

However, when I try the same thing inside Neovim, I get a popup window that just says "Scheduling: /Users/smackesey/stm/code/lib/vim/ifactor/test/ifactor_spec.lua" and nothing else:

:cd /path/to/ifactor/root
:PlenaryBustedDirectory test {minimal=true}

So the test files are correctly discovered but then something goes awry in the execution.

I see something similar with neovim 0.7, I've tried enabling the tests in nixos but it hangs after displaying

I'm seeing this error too now, trying to run the tests for my papis.nvim plugin.

Running nvim --headless -u tests/minimal_init.lua -c 'PlenaryBustedDirectory tests/spec' gives me:

I recently switched from arch to nixos, and it used to work fine before. Running the tests individually works, but that's a bit tedious given the amount of tests. Can I do anything to troubleshoot the issue? @teto, have you ever managed to solve your issue (although it does look like it's somewhat different from mine)?

I'm using the nvim plugins from nixpkgs unstable, so I should have the latest version of plenary.
