Purpose of Software Testing

Why do we perform software testing in a project?

A To find and fix errors before users see the software

B To add new features to the software

C To make the software run faster

D To write documentation for the software

💡 Hint

Think about what testing helps prevent for users.

Software testing helps find bugs early so users get a better experience.

Test Result Interpretation

What will be the output of this test result summary?

Testing Fundamentals

tests = {'passed': 8, 'failed': 2, 'skipped': 0}
if tests['failed'] > 0:
    result = 'Fail'
else:
    result = 'Pass'
print(result)

A Skipped

B Fail

C Error

D Pass

💡 Hint

Check the number of failed tests.

Since there are 2 failed tests, the result is 'Fail'.

❓ assertion

Valid Assertion for Login Function

Which assertion correctly checks that the login function returns True for valid credentials?

Testing Fundamentals

def login(user, password):
    return user == 'admin' and password == '1234'

A assert login('admin', '1234') == True

B assert login('admin', '1234') is False

C assert login('user', '1234') == True

D assert login('admin', 'wrong') == True

💡 Hint

Check which credentials are valid in the function.

Only login('admin', '1234') returns True; others return False.

🔧 Debug

Identify the Testing Code Error

What error will this test code raise when run?

Testing Fundamentals

def test_sum():
    result = sum([1, 2, 3])
    assert result == 6

A AssertionError because result is not 6

B SyntaxError due to wrong assertion syntax

C TypeError because sum is used incorrectly

D No error, test passes

💡 Hint

Look carefully at the assert statement syntax.

The assert statement uses '==' correctly, so no syntax error occurs.

Choosing the Best Test Framework Feature

Which feature is most important in a test framework to support automated regression testing?

A Generating colorful test reports only

B Support for manual test case writing

C Ability to run tests automatically on code changes

D Providing a GUI for test case design

💡 Hint

Regression testing needs frequent automatic runs.

Automated runs on code changes help catch regressions quickly.
