TestB4 is an automated testing system supported by the power of BDD (Behaviour Driven Development). TestB4 helps software teams to collaborate smoothly by enabling simple and readable scenarios free of cluttered technical details. The aim is to close the gap between developers and non-technical participants by creating an explicit common ground for different perspectives.


As software evolves rapidly, TestB4 ensures up-to-date stability in this agile environment. Continuous testing of the specs spots bugs as soon as they appear which avoids trouble and saves time. The system guides organizations to build products working cross browsers and mobile devices.

Throughout the process, development skills are not needed as plain English is just adequate. By using 250+ predefined steps and auto-complete features of the user-friendly editor, a variety of scenarios can be written easily and tested rapidly.

How TestB4 works?

  1. Create a new Git repository on your integrated Git server
  2. Write a new scenario using auto-complete
  3. Configure css / xpath selectors for the pages
  4. Run the test locally and inspect the results
  5. Team members can browse through the scenarios
  6. Schedule tests of any combination of projects & scenarios
  7. Observe results, errors and video recordings of previous tests
