JUnit 3 provides the overridable method tearDown(), to be overridden by subclasses when the test needs to perform some post-test de-initialization. In JUnit 4, this is accomplished by annotating such a method with @After. The method that triggered this error matches the definition of tearDown() from JUnit3, but was not annotated with @After and thus won’t be run by the JUnit4 runner.
If you intend for this tearDown() method not to be run by the JUnit4 runner, but perhaps be manually invoked after certain test methods, please rename the method or mark it private.
If the method is part of an abstract test class hierarchy where this class’s tearDown() is invoked by a superclass method that is annotated with @After, then please rename the abstract method or add @After to the superclass’s definition of tearDown().
Suppress false positives by adding the suppression annotation @SuppressWarnings("JUnit4TearDownNotRun") to the enclosing element.
