Deliver Java code with speed, confidence and insight thanks to AI for Code and the power of unit testing
Diffblue Cover Core uses AI to automatically write JUnit tests so developers don’t have to. The unit tests Cover writes are ready to use immediately; they compile, run and accurately validate the current behavior of your code. Better yet, Cover Core operates completely autonomously - raising and maintaining coverage levels without any developer overhead. Cover Core can write a year’s worth of unit tests in just 8 hours.
Diffblue Cover Reports delivers valuable insights about your Java codebase and lets you pinpoint unique, actionable insights that improve quality and efficiency. Granular unit test coverage reports combine with information on variables like code quality, testability and complexity, for a more holistic view of unit testing. With Cover Reports you can realize more value from unit testing by understanding exactly where risk lies and what to do about it.
Diffblue Cover Optimize lets you deliver better Java code more quickly by minimizing the time needed to run unit tests, whether on the developer desktop or in a Continuous Integration (CI) pipeline, so developers get feedback fast. Instead of running your entire unit test suite to check every code change, with Cover Optimize you only run the JUnit tests required to fully validate that change hasn’t introduced regressions.
Diffblue Cover Refactor is code optimization technology that uses AI to automatically make Java code more testable and increase unit test coverage. Cover Refactor can make the necessary changes to your code automatically, to reduce the risk of regressions and help you get more value from unit testing.
Diffblue Cover Replay helps you improve software quality by unit testing data-driven code, and applications with complex internal states. Cover Replay instruments your application and records selected executions of the code, providing the information needed to write new unit tests that validate real-world application behavior. With Replay you can shift slow, complex functional testing left for faster development.
Diffblue Cover creates suites of unit tests that run in your continuous integration pipeline between versions and protect against regressions, so you can catch errors faster and earlier in the software development lifecycle. To learn more, see our our product page.
Diffblue Cover helps your team increase automation of your CI pipeline.
For development teams, this:
For DevOps teams, this:
Yes. Diffblue Cover quickly generates tests that will allow you to adopt CI. The generated tests will help developers quickly identify regressions in subsequent commits before committing new versions.
See the product datasheet for more information.
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.
