💡 Hint

Common Mistakes

Choosing an approach that tests the whole system instead of parts.

The code sets the testing approach to 'Unit', which is a common starting point for testing small parts of code.

Complete the code to check if the testing strategy includes automation.

Testing Fundamentals

strategy = 'manual'
if strategy == '[1]':
    print('Automation is part of the strategy')
else:
    print('Manual testing only')

💡 Hint

Common Mistakes

Using 'manual' which is the opposite of automation.

The code checks if the strategy is 'automation' to decide the testing method.

Fix the error in the code that decides the testing approach based on input.

Testing Fundamentals

def choose_approach(input):
    if input == '[1]':
        return 'Exploratory Testing'
    else:
        return 'Other Testing'

print(choose_approach('exploratory'))

💡 Hint

Common Mistakes

Using capitalized or uppercase strings that don't match input.

The input is lowercase 'exploratory', so the comparison must match exactly to avoid errors.

Fill both blanks to create a test plan dictionary with approach and priority.

Testing Fundamentals

test_plan = {
    'approach': '[1]',
    'priority': '[2]'
}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Mixing approach and priority values.

The test plan uses 'Risk-based' approach and sets priority to 'High' to focus on important tests.

5fill in blank

hard

Fill all three blanks to create a function that returns a testing strategy summary.

Testing Fundamentals

def strategy_summary(approach, level, focus):
    return {
        'approach': [1],
        'level': [2],
        'focus': [3]
    }

summary = strategy_summary('Exploratory', 'Medium', 'User Experience')
print(summary)

Drag options to blanks, or click blank then click option'

Cfocus

DExploratory

Attempts:

💡 Hint

Common Mistakes

Using keys as values or vice versa.

The function returns a dictionary with keys 'approach', 'level', and 'focus'. The values are passed as arguments, here 'Exploratory', 'Medium', and 'User Experience'.

Practice

1. Why is it important to choose a testing approach before starting testing?

easy

A. It reduces the number of developers needed.

B. It makes the software run faster.

C. It helps decide what to test and how to test it effectively.

D. It guarantees no bugs will be found.

Solution

1. Step 1: Understand the role of testing approaches

   Testing approaches guide the selection of test cases and methods to ensure important parts are tested.

2. Step 2: Connect approach to testing effectiveness

   Choosing the right approach helps focus efforts and improves test coverage and quality.

3. Final Answer:

   It helps decide what to test and how to test it effectively. -> Option C

4. Quick Check:

   Testing approach guides strategy = C [OK]

Hint: Testing approach plans what and how to test [OK]

Common Mistakes:

• Thinking testing approach speeds software
• Believing it reduces team size
• Assuming it removes all bugs

2. Which of the following is the correct syntax to describe a testing approach in a test plan?

easy

A. Use a clear description like 'Black-box testing focusing on input-output behavior.'

B. Write 'Test everything randomly without plan.'

C. Mention only the programming language used.

D. Skip describing the approach to save time.

Solution

1. Step 1: Identify proper test plan content

   A test plan should clearly state the testing approach to guide testers.

2. Step 2: Evaluate options for clarity and relevance

   The option stating 'Use a clear description like "Black-box testing focusing on input-output behavior."' describes a valid, clear testing approach; others are vague or irrelevant.

3. Final Answer:

   Use a clear description like 'Black-box testing focusing on input-output behavior.' -> Option A

4. Quick Check:

   Clear approach description = B [OK]

Hint: Describe approach clearly in test plan [OK]

Common Mistakes:

• Writing vague or irrelevant details
• Ignoring approach description
• Confusing approach with programming language

3. Consider this code snippet representing a test strategy selection:

approach = 'risk-based'
if approach == 'risk-based':
    tests = ['critical features', 'security']
else:
    tests = ['all features']
print(tests)

What will be the output?

medium

A. Error: approach not defined

B. ['all features']

C. []

D. ['critical features', 'security']

Solution

1. Step 1: Check the value of 'approach'

   The variable 'approach' is set to 'risk-based'.

2. Step 2: Follow the if condition logic

   Since approach equals 'risk-based', the code assigns tests to ['critical features', 'security'].

3. Final Answer:

   ['critical features', 'security'] -> Option D

4. Quick Check:

   Approach 'risk-based' selects critical tests = A [OK]

Hint: Match variable value to if condition [OK]

Common Mistakes:

• Confusing else branch output
• Assuming empty list output
• Thinking variable is undefined

4. A test plan states: approach = 'exploratory' but the code uses if approach = 'exploratory':. What is the error and how to fix it?

medium

A. SyntaxError due to '=' instead of '==' in if condition; fix by using '=='

B. Logical error; no fix needed

C. Runtime error because 'approach' is undefined

D. No error; code runs fine

Solution

1. Step 1: Identify the error in the if statement

   The code uses '=' (assignment) inside the if condition, which is invalid syntax in Python.

2. Step 2: Correct the syntax for comparison

   Replace '=' with '==' to compare values properly.

3. Final Answer:

   SyntaxError due to '=' instead of '==' in if condition; fix by using '==' -> Option A

4. Quick Check:

   Use '==' for comparison in conditions [OK]

Hint: Use '==' for comparisons, '=' for assignments [OK]

Common Mistakes:

• Using '=' in if condition
• Ignoring syntax errors
• Confusing assignment with comparison

5. A team wants to improve their testing strategy by combining 'risk-based' and 'exploratory' approaches. Which plan best describes this combined strategy?

hard

A. Focus only on automated tests for all features.

B. Test critical areas based on risk, then explore unexpected issues interactively.

C. Test features randomly without any priority.

D. Skip testing low-risk features entirely.

Solution

1. Step 1: Understand risk-based testing

   Risk-based testing targets critical or risky features first to reduce major failures.

2. Step 2: Understand exploratory testing

   Exploratory testing involves testers exploring the software to find unexpected issues.

3. Step 3: Combine both approaches logically

   The best plan tests high-risk areas first, then uses exploratory testing to find other problems.

4. Final Answer:

   Test critical areas based on risk, then explore unexpected issues interactively. -> Option B

5. Quick Check:

   Combine risk focus + exploration = A [OK]

Hint: Combine risk focus with interactive exploration [OK]

Common Mistakes:

• Ignoring exploratory testing benefits
• Testing randomly without priority
• Skipping low-risk features without checks
