JUnit 5 Repeated Tests - @RepeatedTest
Repeated Tests
Annotating a method with @RepeatedTest repeats the test as many times as the specified value.
The default display name for each repeated execution is repetition <current repetition> of <total repetitions>.
Specifying the Display Name
The name attribute of @RepeatedTest lets you specify the display name for repeated tests. Placeholders can be used in the name.
displayName: Display name of the test method. The default is the method name, but@DisplayNametakes precedence.currentRepetition: Current repetition count, starting at 1.totalRepetitions: Total repetition count.
The predefined long display pattern is {displayName} :: repetition {currentRepetition} of {totalRepetitions}.
Receiving Repetition Information
A test method annotated with @RepeatedTest can receive a RepetitionInfo object as an argument. It provides getCurrentRepetition() and getTotalRepetitions().
RepetitionInfo can also be received in @BeforeEach and @AfterEach. If ordinary @Test methods are mixed in, RepetitionInfo cannot be resolved for those tests and a runtime error occurs.
