Question 21

As the Test Manager for an agile project how would you BEST plan and guide the testing activities during development? SELECT ONE OPTION

A.Ensure testers are separated from the developers to provide an independent set of functional tests
B.Ensure testers are integrated into the development process, helping to review and develop automated unit tests
C.Ensure all tests are written and reviewed by the developers to ensure they reflect the code being developed
D.Ensure testers provide training to developers to help them write a set of auto-mated unit tests

Question 22

You are managing a project that will be using a model-based testing strategy.
Which of the following is an activity that will be needed in order to implement this strategy? [1]

A.Conduct a quality risk analysis with all affected stakeholders.
B.Conduct operational profiling to determine the expected usage of the system.
C.Select an appropriate quality standard, such as ISO 9126, to be used to guide the testing.
D.Create the test charters for the exploratory testing sessions.

Correct Answer: C

A model-based testing strategy is a testing strategy that uses models to represent the desired behavior and structure of the system under test, and to derive test cases, test data, test procedures, and test oracles1. A model-based testing strategy requires an activity to select an appropriate quality standard, such as ISO 9126, to be used to guide the testing. A quality standard is a set of criteria, guidelines, or characteristics that define the quality attributes of a software product, such as functionality, reliability, usability, efficiency, maintainability, and portability2. A quality standard can help to define the quality requirements, objectives, and measures for the system under test, and to evaluate the quality of the test results and the test process3.
Therefore, option C is the correct answer. Option A is incorrect because conducting a quality risk analysis with all affected stakeholders is not an activity specific to a model-based testing strategy, but rather a general testing activity that can be applied to any testing strategy. A quality risk analysis is a process of identifying and assessing the quality risks that may affect the system under test, and prioritizing them based on their impact and likelihood4. Option B is incorrect because conducting operational profiling to determine the expected usage of the system is not an activity specific to a model-based testing strategy, but rather an activity related to a usage-based testing strategy. An operational profile is a statistical representation of the relative frequencies of the inputs, operations, and operating conditions of a system in its operational environment.
Option D is incorrect because creating the test charters for the exploratory testing sessions is not an activity specific to a model-based testing strategy, but rather an activity related to an exploratory testing strategy. A test charter is a document that defines the scope, objective, and approach of an exploratory testing session.

Question 23

Which of the following organizational structures would be considered unorthodox? [1]

A.Developers within the same team unit test each others' code prior to handing over to a separate testing team for system testing
B.Developers and testers are integrated within the same project team, each role focusing on a different level of testing
C.After developers are done unit testing, business analysts alpha test the system before handing over to a separate testing team for system testing
D.DBAs confirm the referential integrity of the database and developers complete their unit testing before handing over to external organization for system testing

Question 24

You have replaced informal code reviews with technical reviews for the most complex and critical components, in an attempt to reduce the high number of defects being found during component and integration test levels. The project manager is concerned about the costs of implementing formal reviews and has asked you to measure whether they actually provide a return on investment.
Which three of the following metrics would be MOST effective in helping you to achieve this?
a. Identification of defect clusters across components
b. Number of lines of code reviewed
c. Number of defects found during reviews d Root cause for each defect detected e Post-review cost of detection and internal failure per defect f. Type of review g. Effort to conduct the review including rework

A.a. f and g.
B.c. e and g.
C.b. d and e.
D.a, c and d.

Question 25

You tend to be conservative in your project estimations because you know how many things can go wrong and extend the schedule. You manager is not happy with your estimates and thinks you are being too negative with your numbers and not trying hard enough Which estimation method should you use to provide your manager with a positive' number while still also providing the number you think is more realistic?

A.Wideband defphi
B.Planning poker
C.Three-point estimation
D.Extrapolation
