Pythagora creates automated tests for you by analysing server activitySee the website
DescriptionGenerate integration tests for your Node.js app by recording server activity without writing a single line of code. Pythagora records all requests to endpoints of your app with the response and everything that's happening during the request. Currently, that means all Mongo and Redis queries with responses (in the future 3rd party API requests, disk IO operations, etc.). Then, when you run the tests, Pythagora can simulate the server conditions from the time when the request was captured.
