EnableJUnit4MigrationSupport is a class-level annotation that enables all JUnit 4 migration support within JUnit Jupiter.

Specifically, this annotation registers all extensions supported by @EnableRuleMigrationSupport and provides support for JUnit 4's @Ignore annotation for disabling test classes and test methods.

Technically speaking, @EnableJUnit4MigrationSupport is a composed annotation which registers all of the following migration extensions: VerifierSupport, ExternalResourceSupport, ExpectedExceptionSupport, and IgnoreCondition. Note, however, that you can optionally register one or more of these extensions explicitly without the use of this composed annotation.
