Exploratory Testing Bug Hunting Techniques 2 — Questions and Answers
Question 1: What is the 'money tour' in James Whittaker's exploratory testing tour metaphor?
- Testing the features most prominently advertised and demonstrated to customers (Correct answer)
- Testing payment processing and financial transaction features
- Running only the tests required for regulatory compliance
- Focusing on revenue-generating APIs and backend services
Correct answer: Testing the features most prominently advertised and demonstrated to customers
The money tour explores the features highlighted in the product's marketing materials and demos — these are what customers expect to work flawlessly.
Question 2: What exploratory testing technique involves inputting unexpected or malformed data to find how the system handles errors?
- Negative testing (Correct answer)
- Equivalence class testing
- Positive path testing
- Smoke testing
Correct answer: Negative testing
Negative testing deliberately provides invalid, unexpected, or malformed input to verify the system handles errors gracefully without crashing or exposing sensitive information.
Question 3: What is 'pairing' as a bug hunting enhancement technique in exploratory testing?
- Two testers exploring the same area simultaneously, sharing observations to find more defects than either would alone (Correct answer)
- Pairing automated tests with manual exploration to increase coverage speed
- Assigning one developer and one tester to each charter for immediate bug fixing
- Running two test sessions against different builds in parallel to compare results
Correct answer: Two testers exploring the same area simultaneously, sharing observations to find more defects than either would alone
Pair testing combines two testers' perspectives, knowledge, and instincts to surface defects that a single tester might miss due to cognitive blind spots.
Question 4: What is the 'saboteur tour' in Whittaker's testing tour framework?
- Testing the application with the intent to make it fail, using the worst possible inputs and usage patterns (Correct answer)
- Testing security features by simulating external attacker behavior
- Testing how the application recovers from unexpected power outages
- A tour focused solely on accessibility and screen reader compatibility
Correct answer: Testing the application with the intent to make it fail, using the worst possible inputs and usage patterns
The saboteur tour challenges the application by doing everything wrong — bad data, wrong sequences, extreme values — to find defects in error handling and robustness.
Question 5: What role does 'note-taking' play during an exploratory bug hunting session?
- It captures test ideas, observations, and findings in real time so nothing is forgotten and the session can be reconstructed (Correct answer)
- It replaces the need for a formal bug tracking system during exploratory sessions
- It documents the exact steps taken so they can be converted into scripted test cases later
- It is required by audit standards for regulated industries only
Correct answer: It captures test ideas, observations, and findings in real time so nothing is forgotten and the session can be reconstructed
Real-time note-taking ensures observations, ideas, and potential bugs are recorded as they occur, making the session reproducible and the tester's reasoning traceable.
Question 6: What is 'scenario-based exploration' as a bug hunting technique?
- Testing a complete end-to-end user journey or workflow to find defects that only appear when features interact (Correct answer)
- Writing formal test scenarios before each session to replace charters
- Testing each scenario from a test design specification document
- Running automated scenario tests generated from BDD feature files
Correct answer: Testing a complete end-to-end user journey or workflow to find defects that only appear when features interact
Scenario-based exploration traces realistic user workflows across multiple features to catch integration defects that unit or isolated feature tests miss.
