Rostyman browser automation test runner with recorded steps, run history, and visual regression diff

The assertDB advantage

Rostyman is the only browser test runner that can assert your database state. After a form submission, check that the correct row was inserted in your database — at the test level, step level, or suite level. No custom hooks, no external scripts. Database and browser integration out of the box.
