🔑 Key Features

Automated Test Generation: Pythagora AI allows developers to generate automated tests for their Node.js applications without having to write a single line of code. It captures requests made to the application’s endpoints, including database queries, and uses them to generate integration tests.

Easy Integration: Integrating Pythagora into a Node.js app is straightforward. Developers simply need to install the Pythagora package and run the Pythagora capture command.

Simulating Server Conditions: During test execution, Pythagora can simulate the server conditions from the time when the request was captured, allowing for accurate testing regardless of the database’s state or the connected environment.

Database Integrity Checks: Pythagora checks the database to ensure that any updates made during the test were done correctly.

Flexible Test Execution: Tests generated by Pythagora can be run on any machine or environment, as it creates a special ephemeral database to restore the data present at the time of test recording.

Pythagora FAQ

Where are the tests saved?

Each captured test is saved in pythagora_tests directory at the root of your repository. Each JSON file in this repository represents one endpoint that was captured and each endpoint can have many captured tests. If you open these files, you will see an array in which each object represents a single test.

How does Pythagora handle authentication?

For authentication Pythagora supports JWT, sessions stored in Redis and sessions stored in MongoDB. When capturing, Pythagora saves timestamp and then in test faze it sends that timestamp to jwt.verify() or updates query to MongoDB depending on your authentication.

How do I edit the tests?

There are many ‘options’ flags you can set with ‘npx pythagora’ command which allow you to delete, edit, rerun tests, etc. You can find more details on our github README.

What is the price of Pythagora?

Pythagora is open source and completely free to use!

What languages/frameworks does Pythagora support?

For now Pythagora supports only NodeJS, to be more specific, apps that are using ‘express’ module and ‘MongoDB’ database.

What about security?

Currently Pythagora doesn’t have any security features so it is NOT recommended to use in production since lot of data will be stored in test json files. They are all stored only locally on your disk but still we do NOT recommend using it in production.
