Unit Testing

Write, execute, and debug unit tests in the language and test framework of your choice. The rich set of built in project templates, and test frameworks support multiple platforms and make it easy to get started.


Dramatically reduce the effort to create and maintain unit tests for new or existing code. Generate interesting input-output values for your methods, and save them as a small test suite with high code coverage. Automatically evolve them as your code evolves.
