js_alternate.vim

Easy navigation between JavaScript alternate files (source and test). Inspired by the amazing vim-rails.

There is one command, :A (alternate) for easy jumping between a JavaScript source file and it’s corresponding test.

Looks for a variety to different test file paths including:

• Root level folders e.g. tests/component/example.js, test/component/example.js, spec/component/example.js
• Sub-folder level folders e.g. src/component/__tests__/example.js
• Suffixed extensions e.g. example.tests.js, example.test.js, example.spec.js
• Underscored folders e.g. src/component/__tests__/example.js, src/component/__test__/example.js, src/component/__spec__/example.js
• Differences of file types between source and tests files e.g. example.js, example.jsx

For a full list of paths checked against see the tests.
