Understanding the primary goal of testing

What is the main purpose of software testing in the development process?

A To fix the defects found in the software

B To find and report defects in the software

C To write code for new features

D To deploy the software to production

💡 Hint

Think about what testing aims to achieve before fixing anything.

Testing is done to identify defects or bugs in the software. Fixing those defects is the next step called debugging.

Distinguishing debugging from testing

Which statement best describes debugging?

A Analyzing and fixing the cause of defects found during testing

B Writing documentation for the software

C Designing test cases for new features

D Running tests to check if the software works as expected

💡 Hint

Debugging happens after defects are found.

Debugging is the process of locating and fixing the root cause of defects found during testing.

Test execution result interpretation

Given the following test code snippet, what will be the test result?

Testing Fundamentals

def add(a, b):
    return a + b

def test_add():
    assert add(2, 3) == 5
    assert add(-1, 1) == 0
    assert add(0, 0) == 1

test_add()

A Test fails with a TypeError

B Test passes successfully with no errors

C Test fails with an AssertionError on the last assertion

D Test fails with a SyntaxError

💡 Hint

Check each assertion carefully for correctness.

The last assertion expects add(0, 0) to be 1, but the function returns 0, so it fails with AssertionError.

❓ assertion

advanced

Choosing the correct assertion for debugging

Which assertion helps identify if a function returns None unexpectedly during debugging?

A assert result is not None

B assert result == 0

C assert result > 0

D assert result != 0

💡 Hint

Focus on checking for None specifically.

Using assert result is not None directly checks if the function returned a value instead of None, which helps catch unexpected None returns.

Identifying the debugging step in a test automation framework

In a test automation framework, which step corresponds to debugging?

A Writing test scripts to verify software behavior

B Running automated tests and collecting results

C Reporting test results to stakeholders

D Analyzing test failures and fixing the underlying code issues

💡 Hint

Debugging is about fixing problems found by tests.

Debugging in a test automation framework involves analyzing why tests failed and correcting the code or environment issues causing those failures.
