Black-box vs white-box testing in Testing Fundamentals - Interactive Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to identify the type of testing that focuses on inputs and outputs without knowing internal code.

Testing Fundamentals

def test_functionality():
    # This is an example of [1] testing
    input_data = 5
    expected_output = 25
    actual_output = square(input_data)
    assert actual_output == expected_output

Common Mistakes

Confusing black-box with white-box testing

Thinking unit testing is the same as black-box testing

Black-box testing checks the software by looking at inputs and outputs without knowing the internal code.

2fill in blank

medium

Complete the code to identify the testing type that requires knowledge of the internal code structure.

Testing Fundamentals

def test_internal_logic():
    # This is an example of [1] testing
    for i in range(10):
        assert process(i) == expected_result(i)

Common Mistakes

Mixing up black-box and white-box testing

Assuming system testing is white-box testing

White-box testing involves looking inside the code to design test cases.

hard

Fix the error in the code to correctly describe black-box testing.

Testing Fundamentals

def describe_testing():
    # Black-box testing focuses on [1] knowledge of the code
    return "Test based on inputs and outputs"

Common Mistakes

Saying black-box testing needs detailed code knowledge

Confusing black-box with white-box testing

Black-box testing does not require any knowledge of the internal code.

Common Mistakes

Choosing inputs or outputs instead of code knowledge

Mixing black-box concepts here

White-box testing requires knowledge of the code and focuses on code coverage.

hard

Fill all three blanks to complete the dictionary comprehension describing testing types.

Testing Fundamentals

testing_types = {
    'black-box': 'Tests based on [1] and [2] without code knowledge',
    'white-box': 'Tests based on [3] knowledge and code structure'
}

💡 Hint

Common Mistakes

Swapping internal and external

Confusing inputs and outputs

Black-box testing is external, based on inputs and outputs. White-box testing is internal, based on code knowledge.
