What decorator is used in unittest to skip a test?

The correct choice is the decorator that directly indicates a test should be skipped for a specified reason. The @unittest.skip("WIP") decorator is specifically designed for this purpose in the unittest framework. When you apply this decorator to a test method, it tells the test runner to skip that particular test and provides a message (in this case, "WIP" for "Work In Progress") as the justification for skipping it.

By using this decorator, developers can easily manage their test suites, especially during development cycles where certain tests may not be ready for execution. This is valuable for maintaining an organized testing process without accidentally running incomplete or failed tests that could mislead the testing results.

The other options mentioned do not exist as part of the unittest library, making them invalid choices for this context. Therefore, recognizing the correct decorator helps developers effectively control their testing workflows in Python.
