Demo Questions
Question 1
Which of the following statements best captures the difference between data-driven and keyword-driven test automation?
- Data-driven test automation extends keyword-driven automation by defining data corresponding to business processes.
- Keyword-driven test automation extends data-driven automation by defining keywords corresponding to business processes.
- Data-driven test automation is more maintainable than keyword-driven test automation.
- Keyword-driven test automation is easier to develop than data-driven test automation.
Correct answer: B
Explanation:
Keyword-driven test automation is a framework where test cases are written using keywords that represent the actions or tests to be performed on the system. This is an extension of data-driven test automation, which focuses on separating test scripts from the test data, allowing the same test script to be run with various sets of data. Keyword-driven test automation further abstracts the process by allowing tests to be written in a more human-readable form that corresponds to business processes. This approach can improve maintainability and readability of test cases, making them easier to understand and modify. It's not necessarily the case that one is more maintainable or easier to develop than the other (Options C and D); rather, they serve different purposes in test automation strategy.

Question 2
A medical company has performed a safety criticality analysis using the IEC61508 standard. The software components to be developed have been categorized by Safety Integrity Level (SIL). Most components have been rated at SIL 1 or 2, and a few components at SIL 4.
After some discussions with the QA manager, the project has decided to adhere to the recommendations for test coverage provided by the IEC61508 standard.
Which level and type of test coverage should at least be used for the components rated at Safety Integrity Level (SIL) 2?
- 100% statement coverage, 100% decision coverage and 100% multiple condition coverage
- 100% statement coverage, 100% decision coverage and 100% MC/DC coverage
- 100% statement coverage and 100% decision coverage
- 100% statement coverage
Correct answer: C
Explanation:
In the context of software testing, different safety integrity levels (SIL) require different levels of rigor in testing. According to the IEC61508 standard, for software components rated at SIL 2, achieving 100% statement coverage and 100% decision coverage is recommended. Statement coverage ensures that every line of code is executed at least once during testing, while decision coverage ensures that every decision in the code (e.g., every branch of an IF statement) is executed on both the true and false sides. These coverage criteria ensure a thorough testing of the software components to validate that they behave correctly in all circumstances. Multiple condition coverage and MC/DC coverage (Options A and B) are more rigorous and typically required for higher SIL levels, such as SIL 4.

Question 3
Consider the pseudo code provided below:
Given the following tests, what additional test(s) (if any) would be needed in order to achieve 100% statement coverage, with the minimum number of tests?
Test 1: A = 7, B = 7, Expected output: 7
Test 2: A = 7, B = 5, Expected output: 5
- A=6, B=12, Expected output: Bingo! and A=7, B=9, Expected output: 7
- A=6, B=12, Expected output: Bingo!
- A=7, B=9, Expected output: 7
- No additional test cases are needed to achieve 100% statement coverage.
Correct answer: D
Explanation:
100% statement coverage means that every line of code is executed at least once during testing. Based on the provided pseudo-code and the test cases given:Test 1 executes the MIN = B statement when A and B are equal.Test 2 executes the MIN = A statement and skips the inner IF since B is not equal to 2*A.All statements within the code have been executed by these two tests, hence no additional test cases are needed to achieve 100% statement coverage. 100% statement coverage means that every line of code is executed at least once during testing. Based on the provided pseudo-code and the test cases given:
Test 1 executes the MIN = B statement when A and B are equal.
Test 2 executes the MIN = A statement and skips the inner IF since B is not equal to 2*A.
All statements within the code have been executed by these two tests, hence no additional test cases are needed to achieve 100% statement coverage.
