More tests written for the Diffblue Cover IntelliJ plugin
Release date: Mar 14, 2022
More plugin tests!
This release, we have updated the Diffblue Cover IntelliJ plugin to include partial tests by default, resulting in more tests written. We have switched on the option of writing tests for enum values by default, too.
We have also added a summary panel so you can easily see how many complete and partial tests have been written:
As shown in this image, you can click on Change Settings if you should want to turn off either of these new default options.
Suppressing SonarQube warnings
SonarQube is a tool to enforce coding practices to help developers write better code. Some of its rules have the purpose to detect common mistakes; others purely concern specific aspects of coding style. Some of the latter rules are a matter of taste and usually need to be tailored to the coding guidelines of a specific project. Using all rules may lead to lots of noisy warnings, and sometimes such warnings are triggered on tests created by Diffblue Cover.
This release, we have added the
--annotate-suppress-warnings option, to reduce the warnings in the tests created by Diffblue Cover. Full details are in our documentation.
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.
How do I automatically maintain all of these tests?
