Switch between a file and its unit test:

demo

On MacOS, press Shift+Cmd+Y.

On Windows / Linux, press Shift+Ctrl+Y.

The following formats are supported:

framework application file unit test file
JavaScript / TypeScript *.js † __tests__/*.test.js
JavaScript / TypeScript *.js † test/*.test.js
JavaScript / TypeScript *.js † test/suite/*.test.js
JavaScript / TypeScript *.js † *.test.js
Python *.py test/test_*.py
Go *.go *_test.go
Ruby on Rails app/*/*.rb spec/*/*_spec.rb
Ruby minitest app/*.rb test/unit/*_test.rb
Ruby minitest app/controllers/*.rb test/integration/*.rb

† Also supports .jsx, .ts, .tsx.

Extension Settings

You can add your own formats by editing test-switcher.rules.

Here's what it would look like to add Ruby on Rails support:

"test-switcher.rules": [
  { "pattern": "app/(.*)\\.rb", "replacement": "spec/$1_spec.rb" },
  { "pattern": "spec/(.*)_spec\\.rb", "replacement": "app/$1.rb" },
]

Effectively, this extension runs path.replace(new RegExp(pattern), replacement). If the source file matches the regex the replaced filename exists, you'll switch to that file. Otherwise, it will try the next rule.

Release Notes

See CHANGELOG.md.
