No test found with unittest framework

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:

Folder Structure

• 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:

Reproduce the report with the supplied project layout, Neovim configuration, and neotest-python unittest runner. Start by checking how unittest discovery is invoked for tests/test_something.py; done means the tests appear in the Neotest summary and related commands while unittest from the CLI continues to work.
