It is as simple as that. If you wish to check the exception that is thrown you can easily get that. It is returned when Assert.Throws is called: One of the new assertion introduced in JUnit 5 is assertAll. This assertion allows the creation of grouped assertions, where all the assertions are executed and their failures are reported together. In details, this assertion accepts a heading, that will be included in the message string for the MultipleFailureError, and a Stream of Executable. So if no exception is thrown, or an exception of the wrong type is thrown, the first Assert.Throws assertion will fail. However if an exception of the correct type is thrown then you can now assert on the actual exception that you've saved in the variable.
