What does exceptions mean?

In software testing, exceptions refer to exceptional events or errors that may occur during the execution of a program. Various factors, such as invalid input, unexpected output, or bugs in the code, can cause these exceptions.

It is important to test for exceptions during testing to ensure that the program can handle them gracefully and continue executing without crashing. This can be done by writing test cases that intentionally cause exceptions to occur and then verifying that the program behaves correctly when an exception is thrown.

Testing for exceptions also includes testing the exception-handling mechanism of the application. This includes testing the try-catch block and the final block to ensure that they are working as expected, releasing any acquired resources, and providing meaningful error messages.
