Common Mistakes

Selecting 'one person' which misses the collaboration aspect

Choosing 'machines' or 'customers' which are not involved directly

Two people working together can discuss and find bugs more quickly than working alone.

Practice

1. What is the main idea behind pair testing in software testing?

easy

A. Testers work in pairs but test different features independently.

B. Two testers work separately on different devices to compare results.

C. Two testers work together on one device to find bugs faster.

D. One tester writes tests while the other writes code.

Solution

1. Step 1: Understand the definition of pair testing and compare options

   Pair testing means two testers work together on one device to collaborate closely. "Two testers work together on one device to find bugs faster." correctly describes this.

2. Final Answer:

   Two testers work together on one device to find bugs faster. -> Option C

3. Quick Check:

   Pair testing = Two testers, one device [OK]

Hint: Pair testing means two testers share one device [OK]

Common Mistakes:

• Thinking testers work separately in pair testing
• Confusing pair testing with pair programming
• Assuming testers test different features independently

2. Which of the following is the correct way to describe the roles in pair testing?

easy

A. Testers switch roles often to keep both active and engaged.

B. One tester tests while the other watches silently without switching roles.

C. Testers work independently and combine results at the end.

D. One tester writes bugs, the other fixes them immediately.

Solution

1. Step 1: Recall role behavior in pair testing and match options

   In pair testing, testers switch roles often to stay active and share knowledge. "Testers switch roles often to keep both active and engaged." correctly states this.

2. Final Answer:

   Testers switch roles often to keep both active and engaged. -> Option A

3. Quick Check:

   Role switching = Active testers [OK]

Hint: Roles switch often in pair testing to stay engaged [OK]

Common Mistakes:

• Assuming one tester is passive
• Thinking testers work independently
• Confusing pair testing with bug fixing roles

3. Consider this scenario: Two testers are pair testing a login feature. Tester A types inputs while Tester B observes and suggests test cases. What is the main benefit of this approach?

medium

A. It allows testers to work on different features simultaneously.

B. It reduces the total number of test cases needed.

C. It ensures only one tester is responsible for bugs.

D. It helps find bugs faster and shares knowledge between testers.

Solution

1. Step 1: Analyze the pair testing scenario and identify the benefit

   Tester A inputs data, Tester B observes and suggests test cases, showing collaboration. This helps find bugs faster and shares knowledge between testers.

2. Final Answer:

   It helps find bugs faster and shares knowledge between testers. -> Option D

3. Quick Check:

   Pair testing benefit = Faster bugs + knowledge sharing [OK]

Hint: Pair testing speeds bug finding and knowledge sharing [OK]

Common Mistakes:

• Thinking it reduces test cases
• Believing only one tester is responsible
• Assuming testers work on different features

4. During pair testing, a team notices that one tester is always controlling the device and the other rarely participates. What is the main problem here?

medium

A. The testers are not switching roles often, reducing engagement.

B. The device is faulty and causing delays.

C. Testers should work independently to be efficient.

D. One tester should write code while the other tests.

Solution

1. Step 1: Identify the issue in pair testing and its impact

   One tester always controls the device, meaning roles are not switching often. This reduces engagement and knowledge sharing.

2. Final Answer:

   The testers are not switching roles often, reducing engagement. -> Option A

3. Quick Check:

   No role switching = Low engagement [OK]

Hint: Lack of role switching reduces tester engagement [OK]

Common Mistakes:

• Blaming the device instead of process
• Suggesting independent work in pair testing
• Confusing testing roles with coding roles

5. You are asked to improve the efficiency of pair testing for a complex feature. Which approach best applies pair testing principles to maximize bug detection and knowledge sharing?

hard

A. Have two testers test separately and merge their bug reports at the end of the day.

B. Assign two testers to work together on one device, switching roles every 15 minutes, discussing findings continuously.

C. One tester tests while the other documents test cases without switching roles.

D. Testers take turns testing different features independently to cover more ground.

Solution

1. Step 1: Identify key pair testing principles and evaluate options

   Pair testing: two testers on one device, switch roles often, share knowledge. "Assign two testers to work together on one device, switching roles every 15 minutes, discussing findings continuously." matches all.

2. Final Answer:

   Assign two testers to work together on one device, switching roles every 15 minutes, discussing findings continuously. -> Option B

3. Quick Check:

   Pair testing best practice = Together + switch roles + discuss [OK]

Hint: Switch roles often and discuss to maximize pair testing [OK]

Common Mistakes:

• Testing separately instead of together
• Not switching roles during testing
• Ignoring communication between testers
