- Eliminate manual testing which is error-prone and time consuming, and must be repeated many times through the PR review process
- Make contributing more fun. For many, fixing bugs and making new badges is faster and more satisfying with automated tests than with manual testing.
- Push out the work of testing new badges to a much broader net. The PR originator could write tests, but so could any other contributor who wants to push review along.
- Detect badge failures resulting from changes in vendor contracts without waiting for user reports.
- Detect and prevent regressions in the code.
- Be runnable, readable, writable, and editable by as many developers as possible, including those who may not be familiar with JavaScript test tools.
