No test found with unittest framework

[TheScianf]

I've just configured neotest but while unittest from cli works, no test seems to be found.
This is my neotest config (lazy plugin manager):

return {
  'nvim-neotest/neotest',
  dependencies = {
    'nvim-neotest/nvim-nio',
    'nvim-lua/plenary.nvim',
    'antoinemadec/FixCursorHold.nvim',
    'nvim-treesitter/nvim-treesitter',
    'nvim-neotest/neotest-python',
    'rcasia/neotest-java',
  },
  opts = {
    adapters = {
      ['neotest-java'] = {},
      ['neotest-python'] = { runner = 'unittest' },
    },
  },
} 

This is my neovim version:

NVIM v0.11.0-dev
Build type: RelWithDebInfo
LuaJIT 2.1.1703358377
Run "nvim -V1 -v" for more info

Here an example:

• src
  • something.py
  • init.py
• tests
  • test_something.py
  • init.py
• init.py

Here I'm running :Neotest summary command and I'm getting the same result with the other commands:

Screencast.from.2025-03-19.11-51-00.webm

I have the same problem in LazyVim. Also I get this error when trying to run tests:

ERROR: test_htmlnode (unittest.loader._FailedTest.test_htmlnode)
----------------------------------------------------------------------
ImportError: Failed to import test module: test_htmlnode

ModuleNotFoundError: No module named 'htmlnode'

Ran 1 test in 0.000s

I have no idea what is the root cause of it.
