How do I test if a Specific Exception Is Raised in a Given Scenario?

To test if a specific exception is raised in a given scenario, you can use the following approaches:

Using a Try-Except Block

Using a Testing Framework
Most testing frameworks, such as unitest (Python), Jest (JavaScript), or JUnit (Java), provide a way to assert that a specific exception is raised.

Python Example (unittest). Import unittest

def divide (a, b):
return a / b

JavaScript Example (Jest)

Test (‘divide by zero’, () => {expect¹.to Error (Range Error).
}); Using a Decorator or Annotation
Some testing frameworks or libraries provide decorators or annotations to specify expected exceptions.

Java Example (JUnit)

By using these approaches, you can effectively test if a specific exception is raised in a given scenario, ensuring the robustness and reliability of your code.
