Question
Which error is thrown if a JUnit assertThrows statement fails?
Solution
If a JUnit assertThrows statement fails, it throws an AssertionError. This error is thrown when an assert statement (a statement that enables you to test your assumptions about your program) fails.
Here's a step-by-step breakdown:
-
You write a JUnit test with an assertThrows statement. This statement is used to test that a specific piece of code throws a specific exception.
-
You run your JUnit test.
-
If the piece of code does not throw the expected exception, the assertThrows statement fails.
-
When the assertThrows statement fails, it throws an AssertionError. This error indicates that an assertion statement has failed.
In summary, an AssertionError is thrown if a JUnit assertThrows statement fails.

What are the results of test case execution? There is an explicit message that test case execution has caused an error in the program. There is an explicit message that there is no error from the test case. The test case has either passed or failed. The program produces an output that is the same as the expected output.
An assertion is a command of the form assert(boolean_expression) that prints an error and exits the program if the boolean expression is false.
