PMD 6.51.0 released

29 October 2022

29-October-2022 - 6.51.0

The PMD team is pleased to announce PMD 6.51.0.

This is a minor release.

The new Apex rule ApexUnitTestClassShouldHaveRunAs ensures that unit tests use System.runAs() at least once. This makes the tests more robust, and independent from the user running it.

<rule ref="category/apex/bestpractices.xml/ApexUnitTestClassShouldHaveRunAs"/>

The rule is part of the quickstart.xml ruleset.

The Java rule TestClassWithoutTestCases has a new property testClassPattern. This is used to detect empty test classes by name. Previously this rule could only detect empty JUnit3 test cases properly. To switch back to the old behavior, this property can be set to an empty value which disables the test class detection by pattern.
