Specto.nvim

Lua Neovim

Specto makes it easy to switch certain test blocks on and off depending on the language and test framework functionality, so that they can be "only" executed or "skipped".

demo.mp4
Move to a certain code block and use one of the provided toggles (see Usage).

Installation

Install the plugin with your preferred package manager:

{
  "cange/specto.nvim",
  dependencies = "nvim-treesitter/nvim-treesitter",
  opts = {}
}

Usage

Allows to toggle certain tests blocks with a only or skip flag (see Supported Language).

Calling one of the following within a spec block such as it(…)

skip()

:lua require('specto.toggle').skip()
-- or
:Specto toggle skip

Toggles it(…) -> it.skip(…) in JavaScript

only()

:lua require('specto.toggle').only()
-- or
:Specto toggle only

Toggles it(…) -> it.only(…) in JavaScript

Note

The feature set depends on the respective language and its testing framework.

Keybindings

The provided commands can either be called directly via :Specto toggle * within a test block or used via keybinding.

vim.keymap.set("n", "<leader>to", "<cmd>Specto toggle only<CR>" )
vim.keymap.set("n", "<leader>ts", "<cmd>Specto toggle skip<CR>" )

Scope

Triggering a toggle only applies to the block in which the cursor is currently located.

describe('context', () => {
  // ↓ toggle applies here
  it.skip('something', () => {
    expect()
    //     ↳  cursor here
  })
})

Configuration

Specto comes with the following defaults:

require("specto").setup({ -- BEGIN_DEFAULT_OPTS
  exclude = {
    filetypes = { -- exclude certain files by default
      "",
      "help",
    }
  },
  languages = {
    -- set default config for all defined languages
    ["*"] = {
      filetypes = {},
      file_patterns = {},
      features = {},
    },
    -- ... other languages
  }
})

See config.lua for more details.

Language Settings

Each language can be define an individual set for only and skip features.

<LANUGAGE_NAME> = { -- eg. javascript
  filetypes = { "javascript", "typescript" }, -- a subset of supported language

  -- Files or directories where tests can be found.
  -- Expects an array of string patterns that can be used with `string.match`.
  file_patterns = {  }, -- eg. `{ "__tests__/", "%.?spec%." }`

  features = {
    -- subset of criteria of each feature
    only { -- or skip
      flag = "only", -- identfier name
      keywords = { "it", "describe", "test" }, -- defines on which blocks it can be attached to
      prefix = false, -- position of flag, false adds flag at the end of a keyword
      separator = ".", -- defines if an flag came with a certain mark eg. `describe.only`
  },
}
