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 an iteration
Which of the following correctly matches each test strategy with an appropriate example?
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?
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 audit ability.
Which of the following answers would you expect to best describe how to organize the test plan?
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?
You are managing the system testing for a SOA based system. The integrated system consists of several subsystems:
- A SOA middleware
- A CRM (Customer Relationship Management) system
- A BRM (Billing and Revenue Management) system
- A SMS (Subscriber Management System) system and you performed a risk analysis based on these subsystems.
At the end of the scheduled period for test execution you produce a first classical report based on the traditional metrics of testing. Test pass/fail status and bug status (open/resolved) That table provides you a distorted picture of the quality risk, because there is no indication of the risk level of the failed tests, the tests not run, or the open bugs. Thus, you produce the following table to solve this distortion issue:
In the table above, where you have introduced the concept of risk weighting, the highest risk test or bug report has a score of 1, while the lowest risk test or bug report has a score of 0.04.
Which of the following subsystems, based on the risk scores of the table, is most risky?
Assume you have some data related to confirmation testing during system testing of a past project.
In that project 240 bug reports have been opened once, 80 were opened twice, 10 were opened three times and no bug reports have been opened more than three
times.
You estimate that a bug report, which has failed its confirmation test, costs, on average, 3 person-hours.
Which of the following statements correctly describe the value of these confirmatory testing activities based on cost of quality?
Which of the following answers describes a factor that may reduce the effort spent when using distributed test teams without negatively affecting system quality?
You are the Test Manager on a project following an iterative life-cycle model. The project should consist of nine iterations of one month duration each. It is planned
to develop the most important features to have a stable core of the application in the first three iterations and to add the additional features in the last six iterations.
At the beginning of the first iteration, only a draft version of the requirements specification document for the core features is available. Assume that during each of
the first three iterations, the chosen features are fully completed and unit tested.
Which of the following statements is true in this context?
Which of the following statements, about the test reporting activities for a project adopting an iterative lifecycle model with very short iterations (e.g. two weeks
iterations), is correct?
