*plenary-test*


Supports (simple) busted-style testing. It implements a mock-ed busted
interface, that will allow you to run simple busted style tests in separate
neovim instances.



USAGE                                                     *plenary-test-usage*
==============================================================================

To run the current spec file in a floating window, you can use the keymap
`<Plug>PlenaryTestFile`. For example:
>
  nmap <leader>t <Plug>PlenaryTestFile
<
In this case, the test is run with a minimal configuration, that includes in
its runtimepath only plenary.nvim and the current working directory.

To run a whole directory from the command line, you could do something like:
>
  nvim --headless -c "PlenaryBustedDirectory tests/plenary/ { <options> }"

Where the first argument is the directory you'd like to test. It will search
for files with the pattern `*_spec.lua` and execute them in separate neovim
instances.

The second argument is a Lua option table with the following fields:

  `nvim_cmd`      specify the command to launch this neovim instance (defaults
                to `vim.v.progpath`).
  `init`          specify an init.vim to use for this instance, if not given
                a minimal configuration is used.
  `minimal_init`  as for `init`, but also run the neovim instance with
                `--noplugin`.
  `sequential`    whether to run tests sequentially (default is to run in
                parallel).
  `keep_going`    if `sequential`, whether to continue on test failure (default
                true).
  `timeout`       controls the maximum time allotted to each job in parallel or
                sequential operation (defaults to 50,000 milliseconds).

Unless `init` is given, the neovim instance is run with the `--noplugin`
argument.

The exit code is 0 for success and 1 for fail, so you can use it easily in
a `Makefile`.



SUPPORTED BUSTED ITEMS                                   *plenary-test-busted*
==============================================================================

So far, the only supported busted items are:

- `describe`
- `it`
- `pending`
- `before_each`
- `after_each`
- `clear`
- `assert.*` etc. (from luassert, which is bundled)

We used to support `luaunit` and original `busted` but it turns out it was way
too hard and not worthwhile for the difficulty of getting them setup,
particularly on other platforms or in CI. Now, we have a dep free (or at
least, no other installation steps necessary) `busted` implementation that can
be used more easily.

Please take a look at the new APIs and make any issues for things that aren't
clear.



COMMANDS                                               *plenary-test-commands*
==============================================================================

*:PlenaryBustedFile* {path}

  Run a test on a single `_spec.lua` file.


*:PlenaryBustedDirectory* {path} {options}

  Run tests for all `*_spec.lua` files in the given path.

  {options} is a table, see |plenary-test-usage|.




PLUGS                                                     *plenary-test-plugs*
==============================================================================

<Plug>PlenaryTestFile

  Can be used to run a test on a single file, with a minimal configuration.
