Unlike in JUnit 3, JUnit 4 tests will not be run unless annotated with @Test. The test method that triggered this error looks like it was meant to be a test, but was not so annotated, so it will not be run. If you intend for this test method not to run, please add both an @Test and an @Ignore annotation to make it clear that you are purposely disabling it. If this is a helper method and not a test, consider reducing its visibility to non-public, if possible.
Suppress false positives by adding the suppression annotation @SuppressWarnings("JUnit4TestNotRun") to the enclosing element.
