No tests found

[armanschwarz]

I've attempted to follow the instructions to install neotest for running python unittest tests:

call plug#begin('~/.config/nvim/plugged')
Plug 'nvim-lua/plenary.nvim'
Plug 'nvim-treesitter/nvim-treesitter'
Plug 'antoinemadec/FixCursorHold.nvim'
Plug 'nvim-neotest/neotest'
Plug 'nvim-neotest/neotest-python'
call plug#end()

lua << EOF
require("neotest").setup({
  adapters = {
    require("neotest-python")({
        -- Extra arguments for nvim-dap configuration
        dap = { justMyCode = false },
        -- Command line arguments for runner
        -- Can also be a function to return dynamic values
        args = {"--log-level", "DEBUG"},
        -- Runner to use. Will use pytest if available by default.
        -- Can be a function to return dynamic value.
        runner = "unittest",

        -- Returns if a given file path is a test file.
        -- NB: This function is called a lot so don't perform any heavy tasks within it.
        is_test_file = function(file_path)
        end
    })
  }
})
EOF

Then I created this python test file:

import unittest

class MyTest(unittest.TestCase):
    def test_my_test_case(self) -> None:
        self.assertTrue(True)

Then I load vim, navigate to "my_test_case" and type :lua require("neotest").run.run() and I just get "No tests found".

[rcarriga]

    is_test_file = function(file_path)
   end

This is going to always say a file path is not a test file because of implicitly returning nil. Remove it from the config

[armanschwarz]

I tried using this instead:

require("neotest").setup({
  adapters = {
    require("neotest-python")({
        -- Extra arguments for nvim-dap configuration
        dap = { justMyCode = false },
        -- Command line arguments for runner
        -- Can also be a function to return dynamic values
        args = {"--log-level", "DEBUG"},
        -- Runner to use. Will use pytest if available by default.
        -- Can be a function to return dynamic value.
        runner = "unittest"
    })
  }
})

But I get the same result.

my_test_case is not a valid test name, please be sure the tests are actually runnable using the unittest cli.

[armanschwarz]

That was just a mve. I changed it to test_my_test_case and it's the same issue.

arman@docker-desktop: ~ $ python -m unittest mytest.py

OK can you update your plugins to the latest, retry and provide the log in vim.fn.stdpath("log") .. "neotest.log"?

Just saw your test file name is mytest.py, this is not an expected test file name. If you run python -m unittest it won't see your file. You should rename it to test_mytest.py. You can force it to be detected by neotest by changing the is_test_file option but it won't work when running directories

[armanschwarz]

Changed the name to test_mytest.py. No change.

arman@docker-desktop: ~/stuff $ python -m unittest

If you use this init.lua does it work? nvim --clean -u min.lua test_mytest.py

-- ignore default config and plugins
vim.opt.runtimepath:remove(vim.fn.expand("~/.config/nvim"))
vim.opt.packpath:remove(vim.fn.expand("~/.local/share/nvim/site"))
vim.opt.termguicolors = true

-- append test directory
local test_dir = "/tmp/nvim-config"
vim.opt.runtimepath:append(vim.fn.expand(test_dir))
vim.opt.packpath:append(vim.fn.expand(test_dir))

-- install packer
local install_path = test_dir .. "/pack/packer/start/packer.nvim"
local install_plugins = false

if vim.fn.empty(vim.fn.glob(install_path)) > 0 then
  vim.cmd("!git clone https://github.com/wbthomason/packer.nvim " .. install_path)
  vim.cmd("packadd packer.nvim")
  install_plugins = true
end

local packer = require("packer")

packer.init({
  package_root = test_dir .. "/pack",
  compile_path = test_dir .. "/plugin/packer_compiled.lua",
})

packer.startup(function(use)
  -- Packer can manage itself
  use("wbthomason/packer.nvim")

  use("vim-test/vim-test")
  use({
    "nvim-neotest/neotest",
    requires = {
      "nvim-lua/plenary.nvim",
      "nvim-treesitter/nvim-treesitter",
      "antoinemadec/FixCursorHold.nvim",
      "nvim-neotest/neotest-python",
    },
    config = function()
      require("neotest").setup({
        adapters = {
          require("neotest-python")({
            dap = { justMyCode = false },
            args = { "--log-level", "DEBUG" },
            runner = "unittest",
          }),
        },
      })
    end,
  })

  if install_plugins then
    packer.sync()
  end
end)

vim.cmd([[
command! NeotestSummary lua require("neotest").summary.toggle()
command! NeotestFile lua require("neotest").run.run(vim.fn.expand("%"))
command! Neotest lua require("neotest").run.run(vim.fn.getcwd())

You'll also have to run TSInstall python and restart after installing plugins

[armanschwarz]

It seems to work with that init.lua file you provided:

  import unittest

  class MyTest(unittest.TestCase):
✔     def test_my_test_case(self) -> None:
          self.assertTrue(True)

I'm confused about what the difference is though, as I thought that the init.vim file I provided in the OP is basically the same thing as what you gave me, but somehow it seems to work. Any ideas?

[armanschwarz]

Ah so I tried again with my init.vim and it actually worked fine after running TSInstall python, so apparently that was the missing step.

 ## Installation

-Neotest uses [plenary.nvim](https://github.com/nvim-lua/plenary.nvim/).
-
-Most adapters will also require [nvim-treesitter](https://github.com/nvim-treesitter/nvim-treesitter).

 Neotest uses the `CursorHold` event which has issues in NeoVim: [see here](https://github.com/neovim/neovim/issues/12587) \
