SuperTest vs Yaak

Both stand on api testing tools. Which one you can start free with, which one lets you read the code, and what each costs once you pay.

SuperTest

SuperTest provides HTTP request and response checks alongside access to SuperAgent methods. Developers using `.end()` should handle assertion errors in the callback so test failures are reported.
