  • How can Test Optimization help? (1:16)

    Tired of waiting for all tests to run every time you make minor changes to your code? Ever risk breaking the build by guessing which tests to run locally, or even worse, not testing at all?

    Test Optimization, aka selective testing, lets you quickly run 'all tests' in your IDE by automatically executing just the tests you need to cover your changes, prioritising those most likely to fail to run first. No risk of omitting a vital test. No time wasted waiting for all tests to run.

  • Testing in the dark? (1:51)

    Not sure where to start? Let Clover show you the way.

    Developing higher quality code is not just about increasing your test coverage percentage, but testing the things that matter most.

    Clover tracks cyclomatic complexity and per-test coverage data to help you identify your biggest project risks and focus your testing where it's needed most.
