See our case study on how Goldman Sachs has benefited from using Diffblue Cover to increase coverage and create a safety net against regressions.
Diffblue regression suites are maintained automatically and updated with each new code version to capture the current behavior of the code.
Diffblue Cover AI analyzes your code and writes Java unit tests that run in a CI pipeline after each commit. Cover’s tests:
No. Diffblue Cover is meant to complement your own unit tests and help you catch regressions.
Developers write individual unit tests to test specific functionality. Diffblue regression suites are generated automatically to help find regressions early in the development cycle. Find out more in our Unit Regression Tests eBook.
