Support for Java 17!
Release date: Apr 11, 2022
Diffblue Cover now supports Java 17!
We have been working hard behind the scenes to get ready to support Java 17, and are delighted to announce that this work is now complete! Diffblue Cover can now be used with Java 8, Java 11 (but please note not version 11.0.7) and Java 17.
Diffblue Cover and Mockito
Diffblue Cover now gives a warning if you are using a version of Mockito that is not supported by the JVM. It also suggests an updated version of Mockito to use, to ensure you get the best outcome and number of tests written.
Support for IntelliJ IDEA 2022.1 - COMING SOON!
We are expecting the release of IntelliJ IDEA 2022.1 any day now, and will be able to support this very shortly. Please look out for the next release!
Developer Edition trial available
We are delighted to now offer a 14-day trial version of our Developer Edition, which includes the Diffblue Cover CLI, as part of our new licensing option. We’re really excited that you can now “try before you buy”! To download your trial of Diffblue Cover Developer Edition, please click here. Full information on all our options is also available here.
