- Question 1Advanced
Core Software Testing Concepts · Errors, defects, and failures
In the context of the error-defect-failure chain, which of the following scenarios strictly represents a "failure"?
Show answer & explanation
Correct answer: A
A failure is the physical manifestation of a defect during execution, resulting in incorrect software behavior (like an application crash). The other options represent errors (human mistakes) or defects (flaws in the code/documentation).

Core Software Testing Concepts · Testing in the SDLC
Which of the following are primary benefits of adopting a "Shift-Left" testing strategy in the Software Development Lifecycle (SDLC)? (Select TWO)
Show answer & explanation
Correct answers: A, C
Shift-Left testing involves introducing testing early in the SDLC (moving it to the 'left' on a timeline). This allows teams to catch defects when they are cheapest to fix and encourages collaboration between testers, developers, and analysts during requirements gathering.

- Question 3Beginner
Core Software Testing Concepts · Testing in the SDLC
How does software testing in an Agile environment primarily differ from a traditional Waterfall methodology?
Show answer & explanation
Correct answer: B
In Agile, testing is a continuous activity that happens in parallel with development throughout the project. In Waterfall, testing is typically a distinct phase that occurs only after the development phase is complete.
- Question 4Intermediate
Core Software Testing Concepts · Risk-based testing strategy
A testing team has limited time before a critical release and cannot execute the entire regression test suite. They decide to allocate 80% of their testing effort to the payment processing and user authentication modules, as failures there would cause significant financial and reputational damage.
This approach is an example of:
Show answer & explanation
Correct answer: B
Risk-based testing prioritizes the testing of features and functions based on the risk of failure (likelihood and impact). By focusing on critical modules like payments and authentication, the team ensures the highest risks are mitigated first.
- Question 5Beginner
Software Testing Types, Levels, and Processes · Types of software testing
Which of the following scenarios is the best example of non-functional testing?
Show answer & explanation
Correct answer: C
Non-functional testing evaluates aspects of the software that are not related to a specific behavior or function, such as performance, usability, reliability, and security. Testing concurrent user load is a performance test, which is non-functional.
- Question 6Intermediate
Software Testing Types, Levels, and Processes · Types of software testing
When comparing manual testing and automated testing, for which of the following tasks is manual testing generally more appropriate?
Show answer & explanation
Correct answer: D
Manual testing excels at tasks requiring human intuition, creativity, and visual evaluation, such as exploratory testing and usability testing. Automated testing is better suited for repetitive, high-volume, or data-intensive tasks.
