D. For system testing, the specification of test conditions at a detailed level, carried out early in the project as soon as the test basis is established, can contribute to defect prevention

The following are the exit criteria described in the test plan of a software product:

EX1. The test suite for the product must ensure that at least each quality risk item is covered by at least one test case (a quality risk item can be covered by more test cases).

EX2. All test cases in the test suite must be run during the execution phase.

EX3. Defects are classified into two categories: "C" (critical defect) and "NC" (non-critical defect). No known C defects shall exist in the product at the end of the test execution phase.

Which of the following information is useless when the specified exit criteria is evaluated?

K2 1 credit

A. A traceability matrix showing the relationships between the product risk items and the test cases

B. A list of all the open defects with the associated classification information extracted from the defect tracking system

C. A chart, showing the trend in the lag time from defect reporting to resolution, extracted from the defect tracking system

D. The execution status of all the test cases extracted from the test management tool

The following chart plots the cumulative number of defects opened against the cumulative number of defects closed during system testing of a software product.

Which of the following statements is true? K2 1 credit

A. The chart indicates that you have plenty of problems left to find

B. The chart can be used to reveal test progress problems

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

K2 1 credit

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 lifecycle

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

D. Mature organizations are aware that risk management of product quality risks only occurs during testing

Which of the following answers describes a factor that may reduce the effort spent when using distributed test teams without negatively affecting system quality?

K2 1 credit

A. Difficulties in communication between the distributed test teams due to time zone differences

B. With several distributed test teams, every team assumes that some test conditions are covered by other teams but actually no one covers them

C. With several distributed test teams, two or more teams assume some test conditions are covered by their team and their team alone. But all of the teams actually cover them

D. With several distributed test teams, all of the distributed test teams use a single unified test dashboard

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?

K2 1 credit

A. I. and III. are true; II. and IV. are false;

B. II. and III are true; I. and IV. are false;

C. III. and IV. are true; I and II are false;

D. I, III and IV are true; II. is false;

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? K3 2 credits

A. Number of defects found during the requirements review

B. Total number of defects attributable to requirements found during unit, integration, system and acceptance testing

C. Total number of defects found during functional specification review, high-level design review, low-level design review, code review, unit testing, integration testing, system testing and acceptance testing

D. Time to conduct the requirements review

E. Total number of defects attributable to requirements, found during functional specification review, high

level design review, low-level design review, code review, unit testing, integration testing, system testing and acceptance testing

During the system testing phase a tester from your test team observes a failure in the system under test and he/she decides to create an incident report. The incident report is currently in a "new" state, indicating it needs to be investigated.

Which THREE of the following information items can't yet be present in the incident report?

K3 2 credits (2 credits out of 3 credits correct, 1 credit point)

A. The type of defect that caused the failure

B. The actual and the expected result highlighting the failure

C. The lifecycle phase in which the defect has been introduced

D. What really caused the failure (actual cause)

E. Steps to reproduce the failure, including screenshots, database dumps and logs where applicable

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?

K4 3 credits (2 credits out of 3 credits correct, 1 credit point)

A. Does the tool support all the types of code coverage required from the three levels A, B, C of the DO178B standard?

B. Does the tool have a good general usability?

C. What are the costs to qualify the tool as a verification tool under the DO-178B?

D. Is the installation procedure of the tool easy?

E. Does the tool require a system with more than 4GB of RAM memory?

F. Is the licensing scheme of the tool compatible with the confidentiality needs of the avionics company?

Your test team consists of four members (Mary, Bob, Mark, Dave) with different interpersonal skills.

The following skills assessment spreadsheet shows the characteristics of the team members with respect to a list of interpersonal-skills (for each characteristic only the member with the highest level of that characteristic is indicated and marked with `X'):

On the next project a member of your test team will have to perform some routine tasks requiring collaboration with other teams.

Who in your test team would you expect to be most suitable at doing these tasks?
