[Question] Can't install neotest for Python

[benabub]

Hello! Pls, some help for newbie!
I have a plugins dir for Lazy in my nvim set. The instruction I've used for all the plugins I've installed:

1. creating plugin-name.lua in this dir with return{} in it
2. paste installation code for Lazy from GitHub's README between brackets

In this case its seems to be more complicated: I had no deal with adapters before.
So, for my neotest.lua file, all I got from my mind palace (and README chunks) is following:

return {
  {
    'nvim-neotest/neotest',
    dependencies = {
      'nvim-neotest/nvim-nio',
      'nvim-lua/plenary.nvim',
      'antoinemadec/FixCursorHold.nvim',
      'nvim-treesitter/nvim-treesitter',
    },
    config = function()
      require('neotest').setup {
        adapters = {
          require 'neotest-python' {
            dap = { justMyCode = false },
          },
          require 'neotest-plenary',
          require 'neotest-vim-test' {
            ignore_file_types = { 'python', 'vim', 'lua' },
          },
        },
      }
    end,
  },
}

The result of such beautiful code is the full screen of red errors:

Failed to run `config` for neotest

Solved by myself.
Working neotest.lua file:

return {
  'nvim-neotest/neotest',
  event = 'VeryLazy',
  config = function()
    require('neotest').setup {
      adapters = {
        require 'neotest-python' {
          env = { CI = true },
          cwd = function(path)
            return vim.fn.getcwd()
          end,
        },
      },
    }
  end,
  dependencies = {
    'nvim-lua/plenary.nvim',
    'nvim-treesitter/nvim-treesitter',
    'antoinemadec/FixCursorHold.nvim',
    'neotest-python',
  },
}

Changes to keymappings.lua file:

-- Neotest
vim.keymap.set('n', '<leader>tn', function()
  require('neotest').run.run()
end, { desc = 'Run nearest test in the file' })

vim.keymap.set('n', '<leader>tt', function()
  require('neotest').run.run(vim.fn.expand '%')
end, { desc = 'Run all the tests in the file' })

vim.keymap.set('n', '<leader>to', function()
  require('neotest').output.open { enter = true }
end, { desc = 'output.open' })

vim.keymap.set('n', '<leader>ts', function()
  require('neotest').summary.toggle()
end, { desc = 'summary_toggle' })

vim.keymap.set('n', '<leader>tw', function()
  require('neotest').watch.watch()
end, { desc = 'watch current test for changes' })
