The "V" process model introduced which idea to the prior "Waterfall model"? a. Variability of requirements b. Debugging as an iterative activity c. Iterative risk assessment d. Validation and verification e. Pairing development activities with testing activities - correct answer ✅e. Pairing development activities with testing activities Over the years, software development process models evolved, got more nuanced, and recognized more intricacies of real software development. What was one of those observed intricacies in regards to quality assurance (QA) activities? a. QA was recognized as having a role later and later in the lifecycle of software development. b. QA was recognized as a more expensive activity. c. QA was recognized as a less expensive activity.

QA was recognized as having a role earlier and earlier in the lifecycle of software development. According to Edsger Dijkstra, testing can only do what? a. Prove the correctness of the software. b. Prove the quality of the software. c. Increase confidence. d. Prove the reliability of the software. e. Prove the presence of bugs - correct answer ✅e. Prove the presence of bugs According to IEEE definitions, a "failure" is: a. A human action that produces an incorrect result. b. The runtime effect of executing a source code anomaly that causes an internal deviation from the expected behavior. c. An anomaly in the source code of a program that may cause a deviation from expected behavior. d. Externally visible output that deviates from the expected output.

correct answer ✅a. An anomaly in the source code of a program that may cause a deviation from expected behavior. According to IEEE definitions, a "error" is: a. The runtime effect of executing a source code anomaly that causes an internal deviation from the expected behavior. b. A human action that produces an incorrect result. c. Externally visible output that deviates from the expected output. d. An anomaly in the source code of a program that may cause a deviation from expected behavior. - correct answer ✅a. The runtime effect of executing a source code anomaly that causes an internal deviation from the expected behavior. What is a "test oracle"? a. An input (or group of inputs) and an expected output. b. A document describing the scope approach, resources, and goals of testing. c. The mechanism for determining the expected or correct behavior for any input.

d. A collection of {input, expected output} pairs. - correct answer ✅c. The mechanism for determining the expected or correct behavior for any input. Which of the following is a good example of the "oracle problem"? a. To compute the exact trajectory to land a rocket on the moon, we have to compute a set of very complex calculations that takes into account many variables. Testing if the computed trajectory is equal to the expected trajectory is difficult, given that we needed to write a computer program to compute the trajectory in the first place — that is, it was too complicated of a calculation to perform manually. b. Testing if software has bugs can only demonstrate that there is a bug if a test failure is found. But, testing can never say that a program is free of bugs because if all test cases pass, that may be a sign that we simply did not test enough. That is, perhaps there are bugs still unfound in the code, and if only we had tested more, we would have found them. c. Validation is more expensive than verification because it requires human effort and cann - correct answer ✅a. To compute the exact trajectory to land a rocket on the moon, we have to compute a set of very complex calculations that takes into account many variables. Testing if the computed trajectory is equal to the expected trajectory is difficult, given that we needed to write a computer program to compute the
