gotospec.nvim

Easily switch between implementation and test files. What I was missing from similar plugins was the ability to automatically create the test/source file if one did not exist.

Installation

Most of the source code is written in Rust so in order to build the plugin Rust needs to be installed on the system.

Using lazy.nvim

{
  "gmartsenkov/gotospec.nvim",
  lazy = false,
  build = "make",
  dependencies = { 'jghauser/mkdir.nvim' }
  config = function()
    require("gotospec").setup({})
  end
}

Assign to a keybinding

["<leader>tt"] = {
  function()
    require("gotospec").jump()
    end,
  "switch between test/implementation"
},

Configuration

Custom configuration can set on a per project basis by creating a .gotospec file in the root of the project.

Example:

{
  "language_configs": {
    "rb": {
      "primary_source_dirs": ["apps", "lib"],
      "test_file_suffix": "_spec",
      "test_file_matcher": "_spec.rb",
      "test_folder":  "spec",
      "omit_source_dir_from_test_dir": true
    }
  }
}

Custom cwd (current working directory)

The plugin uses vim.fn.getcwd() by default to determine the project root, however that won't always be accurate.
To fix this I've created root.nvim which providers a helper function that returns the project root.
The jump method will take an optional cwd path, if that returns nil it'll default to vim.fn.getcwd()
Example usage -

["<leader>tt"] = {
  function()
    require("gotospec").jump(
      require("root").find()
    )
  end
}
