When a test fails due, for example, to infrastructure issues, you might want to ignore it temporarily. But without some kind of notation about why the test is being ignored, it may never be reactivated. Such tests are difficult to address without comprehensive knowledge of the project, and end up polluting their projects.
For annotation: Either add an explanation about why this test is skipped or remove the "[@Ignore|@Disabled]" annotation.
For assumeX calls: This assumption is called with a boolean constant; remove it or, to skip this test use an @Ignore/@Disabled annotation in combination with an explanation about why it is skipped.
