Test Switcher

Switch between a file and its unit test:

On MacOS, press Shift+Cmd+Y.

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

The following formats are supported:

framework	application file	unit test file
all	*.*	*.test.*
JavaScript / TypeScript	*.*	__tests__/*.test.*
JavaScript / TypeScript	*.*	test/*.test.*
JavaScript / TypeScript	*.*	test/suite/*.test.*
JavaScript / TypeScript	*.*	*.stories.*
Python	*.py	test/test_*.py
Python	src/*/*.py	test/*/test_*.py
Go	*.go	*_test.go
Ruby on Rails 1-5	app/*/*.rb	spec/*/*_spec.rb
Ruby on Rails 6+	app/*/*.rb	test/*/*_test.rb
Ruby minitest	app/*.rb	test/unit/*_test.rb
Ruby minitest	app/controllers/*.rb	test/integration/*.rb

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.
