Junit5: TestInfo: Get information about the test

TestInfo class is used to inject information about the current test or container into a @Test, @RepeatedTest, @ParameterizedTest,  @TestFactory, @BeforeEach, @AfterEach, @BeforeAll, and @AfterAll methods.

 

If a constructor or method parameter is of type TestInfo, the TestInfoParameterResolver will supply an instance of TestInfo corresponding to the current container or test as the value for the parameter.

 

Using TestInfo instance, you can retrieve information about the current container or test such as the display name, the test class, the test method, and associated tags
