About
Checksum is an AI-powered tool that automatically generates and maintains end-to-end tests for web applications. It leverages machine learning models trained on real user sessions to create comprehensive test suites covering both happy paths and edge cases. The generated tests are self-maintaining and auto-healing, eliminating flakiness and reducing maintenance overhead. Checksum integrates with popular tools like Playwright, Cypress, Github, Gitlab, Jenkins, and CircleCI, and requires minimal integration effort (2 lines of Javascript). Checksum offers full test coverage within days, saving months of development time and enabling faster, bug-free releases.

FAQs
How are you generating the tests and what is your coverage?
We train an AI model on real user sessions from your production environment. Our models learn how your users use your app, how they interact with elements, and the typical as well as the edge cases flows they take. Then we connect the model to a browser, gives it a username and password and let it generate tests. Since our model is trained specifically on your software, it executes every edge case and produces automated tests.
How can you test new features if your model is trained on user sessions?
Our model can extrapolate from production sessions and learn even how to test new features. By learning your UI conventions and how they manifest in real sessions, we can then generate tests for new features on the spot no new sessions.
What kind of tests are you generating?
Checksum.ai is using ML to generate end-to-end tests using Cypress or Playwright code.
What data are you collecting? Do you have any impact on my production performance?
To train the model, we are recording your user sessions in a similar way to solutions like Fullstory or Hotjar. To protect your users' privacy, we can work on staging only or completely anonymize data collection. Our impact on performance is non-existent as we use battle-tested open source tools used by Fortune 500 companies.
Is the SDK Integration required?
Not necessarily. We can also teach the model using help articles. To evaluate feasibility schedule a demo with us.
