ISTQB Test Manager TM12 Questions & Answers

• Question 31:

  Which one of the following metrics to be produced needs traceability between the test cases and each item in a proper test basis?

  A. Requirements coverage

  B. Trends in the lag time from defect reporting to resolution

  C. Mean time between failures for the system

  D. Cumulative number of reported defects versus cumulative number of resolved defects

  Correct Answer: A

• Question 32:

  After the presentation, you are asked to explain the chart. Assume you have applied a full risk-based testing strategy.

  

  Which of the following answers would you expect to best describe the pie chart?

  A. All the risk items have been covered with tests. No more risk items remain to test.

  B. According to the full risk-based testing strategy applied, it is very likely that the highest-risk items, tests and bugs remain in the blue and red areas. Therefore, it is very risky to release the application.

  C. Only the lowest-risk items, tests and bugs should remain in the blue and red areas. Therefore, the application can be released at any time subject to management of the items identified in those areas.

  D. 97 percent of the risk items has been tested. No open bugs or test failures remain. Only 3 percent of risk items remains to be covered by the remaining test.

  Correct Answer: C

• Question 33:

  Based on the historical data of 5 past and similar projects, you have calculated these average numbers of defects detected in system testing:

  for each 10000 LOC (lines of code), 200 defects for each person-month of development team effort, 49 defects

  You want to use this information to perform estimation for a new project.

  The project manager tells you that he/she has estimated 20000 new LOC for this new project.

  Four developers work for four months on this project before system testing.

  During system testing, 797 defects are discovered.

  Assume that the system test of this new project is using the same amount of work as spent in the past projects.

  Based on this information only, which of the following statement is certainly true about this project?

  A. The code for the new project contains a higher defect density than the code of the past projects.

  B. The number of defects found during the system test phase on the new project is approximately proportional to the development team effort.

  C. 40000 LOC have been delivered to system testing (against the 20000 LOC planned by the project manager).

  D. More LOC than planned have been delivered to system testing with a higher defect density than the past projects.

  Correct Answer: B

• Question 34:

  You are estimating the effort for the integration testing activities of a new project. Consider the following factors, which can affect that estimation:

  I. Availability of re-usable test systems and documentation from previous, similar projects

  II. Unexpected timing of components arrival

  III. Stability of the integration test team (no turnover)

  IV. Many and geographically distributed sub-teams

  Which of the following statements is true?

  A. I and II can negatively affect the estimation III and IV usually favor the accuracy of the estimation effort

  B. II and III can negatively affect the estimation I and IV usually favor the accuracy of the estimation effort

  C. II and IV can negatively affect the estimation I and III usually favor the accuracy of the estimation effort

  D. III and IV can negatively affect the estimation I and II usually favor the accuracy of the estimation effort

  Correct Answer: C

• Question 35:

  You are the Test Manager of a new project that will have three formal levels of testing: unit, integration and system testing. The testing strategy you decide to adopt a blend of risk-based testing and reactive testing strategies.

  Which of the following answers describes the most consistent example of implementation of this test strategy during the execution of the system tests?

  A. Your test team executes exploratory tests following a session-based test management approach throughout the system test phase.

  B. Your test team executes system tests under the guidance of a sample of users throughout the system test phase.

  C. Your test team executes scripted tests designed and implemented before the execution of the system test phase, to cover the identified product risks. It also performs exploratory testing sessions throughout the system test phase.

  D. Your test team autonomously performs some exploratory testing sessions and, at the very end of the system testing phase, it also executes more system tests under the guidance of a sample of users.

  Correct Answer: C

• Question 36:

  You are the Test Manager of a new project aimed at developing a software system that must be certified at level B of the DO-178B standard. The project will follow a V-Model software development life cycle and it will have four formal levels of testing: component, integration, system and acceptance testing.

  You must produce the test plan documentation for this project by providing an adequate coordination across the four levels of testing in order to assure auditability.

  Which of the following answers would you expect to best describe how to organize the test plan?

  A. Produce a single master test plan that covers in detail all four levels, describing the particular activities for all test levels.

  B. Produce a master test plan that covers three levels (component, integration, system test) and a separate acceptance test plan.

  C. Produce a master test plan describing the relationship between the four levels, and four separate detailed level test plans, one for each level.

  D. Produce four separate detailed level test plans, one for each level, without a master test plan.

  Correct Answer: C

• Question 37:

  In the next two months some new features will be constantly added to new releases of a project you are

  working on as Test Manager.

  You have identified as one of the main project risks, that the requirements specification will still be

  incomplete when your team starts the test design and implementation phase.

  Some requirements will most likely be completed too late to allow a proper test preparation.

  You and your test team have already worked on several similar past projects in the same organization.

  Which one of the following options would you expect to be the most effective at mitigating this risk?

  A. Don't prepare any test and just run the regression test suite to check that the new features don't introduce regression.

  B. Make reasonable assumptions about the missing details and design lightweight tests that can be easily updated during test execution.

  C. Don't design any test until the test execution starts, then communicate that test execution is blocked due to incomplete requirements.

  D. Even if there are only few details missing, escalate the risk to the project manager without preparing any tests.

  Correct Answer: B

• Question 38:

  Consider the following test strategies:

  I. Consultative test strategy

  II. Reactive test strategy

  III. Analytical test strategy

  IV. Process-compliant test strategy

  Consider also the following examples of test activities:

  1.

  Prioritize the test cases, based on the results of a FMEA analysis, to ensure early coverage of the most important areas and discovery of the most important defects during test execution

  2.

  Execute usability testing driven by the guidance of a sample of users (external to the test team)

  3.

  Perform exploratory testing sessions throughout the system test phase

  4.

  On an Agile project, execute tests that cover the test conditions identified for each user story of a feature planned for iteration

  Which of the following correctly matches each test strategy with an appropriate example?

  A. I-2; II-3; III-4; IV-1

  B. I-3; II-2; III-1; IV-4

  C. I-1; II-2; III-3; IV-4

  D. I-2; II-3; III-1; IV-4

  Correct Answer: D

• Question 39:

  In the test strategy document your organization declares:

  to adopt a V-model development lifecycle, with three formal levels of testing: unit, integration and system testing to use a blended risk-based and regression-averse testing strategy for each level of testing

  The following is an excerpt of the "approach" section for the system test plan document of a new project:

  "Testing will only use manual tests. Due to the short period of time for test execution, the following activities will be performed in parallel with test execution: Test planning, test analysis and test design.

  Basic metrics will be taken for test effort (i.e. person-hours), test cases executed (passed/failed), and incidents (no more metrics, such as code coverage, will be collected)."

  In the system test plan, no deviations from the test strategy are described. Based only on the given information, which of the following statements is true?

  A. The approach described in the system test plan document is consistent with the test strategy.

  B. The approach described in the system test plan document is consistent with the risk-based testing strategy, but it is inconsistent with the regression testing strategy.

  C. The approach described in the system test plan document is consistent with the regression testing strategy, but it is inconsistent with the risk-based testing strategy.

  D. The approach described the system test plan document is inconsistent with both the risk-based and regression testing strategies.

  Correct Answer: D

• Question 40:

  Which of the following statements about management of product quality risks in mature organizations with respect to the lifecycle, is true?

  A. Mature organizations address product quality risks associated to non-functional characteristics only during the system test phase.

  B. Mature organizations are aware that the contribution of testing to analysis of product quality risks is very important. The analysis should occur throughout the entire life cycle.

  C. Mature organizations don't waste time identifying the sources of risks. They only focus on identifying product quality risks.
