UnitTestAssertionsShouldIncludeMessage

Usage: pmd check -d <source code folder> -R category/java/bestpractices.xml/UnitTestAssertionsShouldIncludeMessage -format <output format>

Description:

JUnit assertions should include an informative message - i.e., use the three-argument version of assertEquals(), not the two-argument version.

Example:

public class Foo extends TestCase {
    public void testSomething() {
        assertEquals("foo", "bar");
        // Use the form:
        // assertEquals("Foo does not equals bar", "foo", "bar");
        // instead
    }
}
