JUnit 5, also known as Jupiter, introduces the @RepeatedTest annotation, which allows test cases to be executed multiple times with the same input data. This feature is particularly useful in scenarios where test cases need to handle randomness or environmental inconsistencies, such as variations in web page load times or transient errors. The @RepeatedTest annotation is treated similarly to the @Test annotation, supporting lifecycle callbacks like @BeforeEach and @AfterEach. Users can customize display names for repeated tests using placeholders to enhance readability and understanding of test execution outputs. The RepetitionInfo interface provides methods to retrieve information about the current and total repetitions, while the RepeatedTest interface allows for accessing attributes of the @RepeatedTest annotation. Leveraging a cloud-based platform like LambdaTest can enhance the execution of JUnit tests on a global scale, providing increased efficiency and flexibility.
