Diffblue Cover is an automated unit test-writing tool. It analyses your existing Java application and writes unit tests that reflect the current behavior, increasing test coverage and helping you find regressions in future code changes. Diffblue Cover automatically maintains the tests by updating them when your code changes. It supports standard Java 8, 11 & 17, Spring and Spring Boot.
