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.
