Configuration

{
  "nvim-neotest/neotest",
  dependencies = {
    ...,
    "marilari88/neotest-vitest",
  },
  config = function()
    require("neotest").setup({
      ...,
      adapters = {
        require("neotest-vitest") {
          -- Filter directories when searching for test files. Useful in large projects (see Filter directories notes).
          filter_dir = function(name, rel_path, root)
            return name ~= "node_modules"
          end,
        },
      }
    })
  end,
}

Stricter file parsing to determine test files

Use is_test_file option to add a custom criteria for test file discovery.

---Custom criteria for a file path to determine if it is a vitest test file.
---@async
---@param file_path string Path of the potential vitest test file
---@return boolean
is_test_file = function(file_path)
    -- Check if the project is "my-peculiar-project"
    if string.match(file_path, "my-peculiar-project") then
        -- Check if the file path includes something else
        if string.match(file_path, "/myapp/") then
            -- eg. only files in __tests__ are to be considered
            return string.match(file_path, "__tests__")
        end
    end
    return false
end,

Filter directories

Use filter_dir option to limit directories to be searched for tests.

---Filter directories when searching for test files
---@async
---@param name string Name of directory
---@param rel_path string Path to directory, relative to root
---@param root string Root directory of project
---@return boolean
filter_dir = function(name, rel_path, root)
  local full_path = root .. "/" .. rel_path

  if root:match("projects/my-large-monorepo") then
    if full_path:match("^unit_tests") then
      return true
    else
      return false
    end
  else
    return name ~= "node_modules"
  end
end

Watch mode mappings

vim.api.nvim_set_keymap(
    "n", 
    "<leader>twr", 
    "<cmd>lua require('neotest').run.run({ vitestCommand = 'vitest --watch' })<cr>", 
    {desc = "Run Watch"}
)

vim.api.nvim_set_keymap(
    "n",
    "<leader>twf",
    "<cmd>lua require('neotest').run.run({ vim.fn.expand("%"), vitestCommand = 'vitest --watch' })<cr>",
    {desc = "Run Watch File"}
)
