If any assert statement fails, test results are failed.

If no exception is thrown from the executable block, or if an exception of a different type is thrown, assertThrows () method will fail. Please note that if the code block throws an exception of a class that is a subtype of the expected exception type, then the assertion will pass. For example, if we are expecting IllegalArgumentException and the test throws NumberFormatException then also the test will PASS because NumberFormatException extends IllegalArgumentException class.

The test is red if the test method throws no exception or a different exception. 2019-11-02 · For example, if we are expecting IllegalArgumentException and the test throws NumberFormatException then also the test will PASS because NumberFormatException extends IllegalArgumentException class. This also means that if we pass Exception.class as the expected exception type, any exception thrown from the code block will make the assertion succeed since Exception is the super-type for all exceptions.
