How to test

Write Unit Test

Write unit test file which name suffixed with "_spec.lua" in same directory with source file.

Excute Unit Test

Just run make test to excute unit test.

If you want more operations, read below sections.

Excute Specific Unit Test

Open unit test file in nvim. Run :TestLuaSpec to run unit test.

Excute Unit Tests in Directory

To run a whole directory "./lua" from the command line.

nvim --headless -c "PlenaryBustedDirectory lua"

Headless Test Options

nvim --headless -c "lua require('plenary.test_harness').test_directory('lua', { timeout = 5000 })"

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

• minimal_init: specify an init.vim to use for this instance, uses --noplugin
• minimal: uses --noplugin without an init script (overrides minimal_init)
• 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)
