You are following a risk-based testing strategy. The test execution time is very limited. Assume that all the product risk items require more or less the same level of test effort.
Which of the following answers describes the best execution schedule in this scenario?
Number of correct responses: 1

Assume that the following test cases have been executed at the end of the first week of test execution: TC-001, TC-002 and TC-007. All these tests are ‘passes’.
What is the MINIMUM number of the remaining test cases that must be successfully executed to fulfill the EX1 exit criteria?

The following is the unique “critical” quality risk item that has been identified:
CR-RSK-1. The GUI of the application might accept non-integer values for the input field designed to get the number of bottles from the user
Test analysis for system testing has just begun and the following test conditions have been identified:
TC-SEL-2. Test the selection of the package sizes
TC-SEL-4. Test wrong numbers of bottles for an order
TC-CR-RSK-1. Test the accepted values from the input field designed to get the number of bottles from the user
What is the MINIMUM number of test conditions that must be added to fulfill both the EXCR1 and EXCR2 exit criteria?

Reviews
You are the Test Manager of a project that adopts a V-model with four formal levels of testing: unit, integration, system and acceptance testing.
On this project reviews have been conducted for each development phase prior to testing, which is to say that reviews of requirements, functional specification, high-level design, low-level design and code have been performed prior to testing.
Assume that no requirements defects have been reported after the release of the product.
Which TWO of the following metrics do you need in order to evaluate the requirements reviews in terms of phase containment effectiveness?
Number of correct responses: 2
K32 credits
During the follow-up phase the following conditions are checked:
X1. The code has been completely reviewed
X2. All the identified defects have been correctly fixed and the modified code has been compiled successfully and run through all the static analyzers used by the project without warnings and errors
X3. The modified code is available under the configuration management system with a new version number for the specified CI
If these conditions are fulfilled then the review process terminates.
Which of the following characteristics of a formal review is missing in this description?

Reviews
Consider the following list of statements about audits and management reviews:
I. Audits are usually more effective than management reviews at finding defects
II. Audits and management reviews have the same main goals, the only difference is related to the roles and level of formality
III. A typical outcome of an audit includes observations and recommendations, corrective actions and a pass/fail assessment
IV. An audit is not the appropriate mechanism to use at the code review in order to detect defects prior to dynamic testing
Which of the following statements is true?
Number of correct responses: 1
K21 credit
The main objectives the senior management team wants to achieve are:
- to reduce the costs associated with dynamic testing
- to use reviews to ensure that the project is on course for success and following the plan
- to use reviews as a well-documented and effective bug-removal activity following a formal process with well-defined roles
- to determine the effectiveness of reviews in terms of phase containment
- to improve phase containment effectiveness
Which of the following answers would you expect to describe the best way to achieve these objectives?
Number of correct responses: 1

Test Tools and Automation
Assume you are the Test Manager in charge of independent testing for avionics applications.
You are in charge of testing for a project to implement three different CSCI (Computer Software Configuration Item):
- a BOOT-X CSCI that must be certified at level B of the DO-178B standard
- a DIAG-X CSCI that must be certified at level C of the DO-178B standard
- a DRIV-X CSCI that must be certified at level A of the DO-178B standard
These are three different software modules written in C language to run on a specific hardware platform.
You have been asked to select a single code coverage tool to perform the mandatory code coverage measurements, in order to meet the structural coverage criteria prescribed by the DO-178B standard. This tool must be qualified as a verification tool under DO-178B.
Since there are significant budget constraints to purchase this tool, you are evaluating an open-source tool that is able to provide different types of code coverage. This tool meets perfectly your technical needs in terms of the programming language and the specific hardware platform (it supports also the specific C-compiler).
The source code of the tool is available.
Your team could easily customize the tool to meet the project needs. This tool is not qualified as a verification tool under the DO-178B.
Which of the following are the three main concerns related to that open-source tool selection?
Number of correct responses: 3
