Assume you are currently working on a project developing a system where functional
requirements are very well specified. Unfortunately non-functional requirements do almost not exist.
You are the Test Manager. You have to choose a technique for test selection that allows testing of non-functional characteristics, especially reliability.
Which of the following techniques for test selection do you expect being most useful in this scenario?

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? K4 3 credits
Assume you are managing a test automation project for a mission-critical system. Because vendor provided tools and open source solutions don't meet the needs of this project, you ask your test team to develop a custom automation framework. Which of the following management issues associated to the development of this custom automation framework is least likely to manage?

Assume that you are the Test Manager for a small insurance application development project. You have decided to adopt a risk-based testing strategy: 5 product risks (R1, R2, R3, R4, R5)
have been identified and their levels of risk have been assessed. 10 test cases (T1, ..., T10) have been designed to cover all the product risks.
The following table shows the risk level and the test cases associated to the identified product risks (higher risk level means higher risk):
You are not confident with the assessment of the risk level and you suspect that it will be possible to find high-priority bugs in low-risk areas.
Furthermore the period for test execution is very short. Your goal is to test all the product risks in a risk-based way, while assuring that each product risk gets at least some amount of testing. Which of the following answers describes the best test execution schedule in this scenario? K3 2 credits
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?
