Testing the Code Bug Fixer app

Now, we will learn how to test our Code Bug Fixer application. We will write some test cases to ensure that the application is functioning correctly and handling different scenarios appropriately. Testing is a critical part of software development, as it ensures that the application works as intended and meets the user’s requirements.

The Code Bug Fixer app can fix any programming language, making it a versatile tool. Therefore, we will demonstrate its effectiveness by using examples written in two different programming languages: Java and Python.

Our Python example has two properties. Firstly, we have the following buggy code:

def factorial(n):
    if n == 0:
        return 1
    else:
        return n * factorial(n-1)
print("The factorial of 5 is: " + factorial(5))

Then, you can enter the following error...
