Feature

WOuld be nice to only run tests on those components impacted by the change. For example,

• Readme changes don't do any tests
• core lib changes might have to run everything
• transform X change only runs tests on transform X
• etc.

From Matsubara-san: " found an action to detect changed files https://github.com/marketplace/actions/changed-files Using this you can branch out the execution of the test cases. If some of them are specified as PR check, then you can run a no-op test script instead to pass the check."
