Question 1 of 87

The four test levels defined for a common V-model testing approach are:

Unit, integration, system and maintenance.

Functional, glass box, incremental and maintenance.

Component, integration, system and acceptance.

Unit, component, functional and alpha/beta.

Correct Answer: C

The four test levels defined for a common V-model testing approach are component, integration, system, and acceptance. Each of these stages corresponds to a different phase of software development and ensures thorough testing of the software product at multiple levels of granularity. Thus, the correct answer is component, integration, system, and acceptance.

Question 2 of 87

Typically, exit criteria may consist of:

Defining the amount, level of detail structure, and templates for the test documentation.

Estimates of defect density or reliability measures.

Adequacy of the test approaches taken.

Discussions on disaster recovery.

Correct Answer: B

Exit criteria typically include estimates of defect density or reliability measures to assess whether the software product has met the required quality standards and is ready for release. This ensures that sufficient testing has been done and that the product is reliable and free of critical defects before moving on to the next phase or release.

Question 3 of 87

A data driven approach to test automation design is best described as:

Using action words to describe the actions to be taken, the test data.

Scaling to support large numbers of users.

Being based on Equivalence Partitioning testing techniques.

Separating out the test data inputs and using a generic script that can read the test data and perform the same test steps with different data.

Correct Answer: D

A data-driven approach to test automation design involves separating the test data from the test scripts. This means using a generic test script that can read varying test data inputs and perform the same test steps with different sets of data. This approach allows for greater flexibility and scalability in testing, as new test cases can be created simply by adding new data sets without modifying the test scripts themselves.

Question 4 of 87

Which of the following risks represents the highest level of risk to the project?

Likelihood of failure = 1%, potential cost of impact = $1m.

Likelihood of failure = 10%, potential cost of impact = $500,000.

Likelihood of failure = 20%, potential cost of impact = $150,000.

Likelihood of failure = 5%, potential cost of impact = $500,000.

Correct Answer: B

To determine the highest level of risk to the project, we calculate the expected cost of impact for each option, which is the product of the likelihood of failure and the potential cost of impact. For option A: 1% of $1,000,000 equals $10,000. For option B: 10% of $500,000 equals $50,000. For option C: 20% of $150,000 equals $30,000. For option D: 5% of $500,000 equals $25,000. Option B has the highest expected cost of impact, therefore it represents the highest level of risk to the project.

Question 5 of 87

What factors should be considered to determine whether enough testing has been performed?

(i)The exit criteria.

(ii)The budget.

(iii)How big the test team is.

(iv)The product's risk profile.

(v)How good the testing tools are.

(vi)Sufficient details of the system status to allow decisions

i and ii and iv and vi

i and ii and iii and vi

ii and iii and iv and v

i and ii and v and vi

Correct Answer: A

To determine whether enough testing has been performed, it is essential to consider the exit criteria, which provide clear guidelines for when testing is complete. The budget is also a critical factor, as limited resources can constrain the amount of testing that can be done. The product's risk profile is important because higher-risk products may require more extensive testing to mitigate potential issues. Additionally, having sufficient details of the system status allows informed decision-making regarding the adequacy of testing. These factors (i, ii, iv, and vi) are key to making an informed determination about the completeness of the testing process.
