Since it was launched on Sept 8th, the Community Edition of Diffblue Cover has been downloaded by more than two thousand developers, and has created over 100,000 unit tests. If each unit test takes (a conservative estimate of) 10 minutes to write, then these have already saved users 4,000+ developer days.

What kinds of tests does Diffblue Cover write?

The Java unit regression tests created by all versions of Diffblue Cover are written to be readable and are automatically maintained, and can quickly increase code coverage. This helps developers find errors, bugs, and other issues earlier, and it can also catch edge cases that humans might miss.

How to get it

Community Edition is a completely-free-forever plugin for IntelliJ that creates unit tests for open-source Java projects. It’s available to download on our website or on the JetBrains marketplace
