This means that if we pass Exception as the expected exception type, any exception thrown will make the assertion succeed since Exception is the super-type for all exceptions.

They are used to verify the correctness of an invariant in the code. They should never be triggered in production code, and are indicative of a bug or misuse of a code path. public class Assert extends java.lang.Object. A set of assertion methods useful for writing tests.
