Correct : C

Statement coverage is a white-box test technique which focuses on the percentage of executable statements that has been executed by a test suite. This is the best description of statement coverage, as it measures how many statements in the source code have been covered by one or more test cases. Option A is incorrect, as it describes state transition testing, which is a black-box test technique that uses a state table to derive test cases. Option B is incorrect, as it describes error guessing, which is an experience-based test technique in which test cases are based on the tester's knowledge of past failures. Option D is incorrect, as it describes decision coverage, which is a white-box test technique that covers the decision results which determine the next statement to be executed.

Correct : D

The correct matching of the descriptions with the different categories of test techniques is as follows:

Black-box test techniques: Test cases are based on the test basis which may include the requirements, use cases and user stories (1), Test cases can show deviations from the requirements (3), These test techniques are applicable to both functional and non-functional testing (4)

White-box test techniques: Test cases are based on the test basis which may include the software architecture or code (2)

Experience-based test techniques: Tests are based on knowledge of developers, users and other stakeholders (5)

Therefore, option D is the correct answer. Options A, B, and C are incorrect, as they do not match the descriptions with the different categories of test techniques correctly.

Correct : B

The correct answer is B, as it achieves the highest equivalence partition coverage.Equivalence partitioning is a black-box test technique that divides the input domain into partitions of equivalent data from which test cases can be derived1. In this case, the input domain is the numerical grades, and the partitions are the ranges of grades that correspond to different letter grades. Option B covers all five partitions, as it includes test inputs from each range. Option A covers only four partitions, as it does not include any test input from the range above 89. Option C covers only three partitions, as it does not include any test input from the ranges above 79 and below 60.Option D covers only two partitions, as it does not include any test input from the ranges below 79. Reference:1, Section 4.2.3

Correct : C

The correct answer is C, as three additional test cases are needed to ensure full coverage of all valid input equivalence partitions.Equivalence partitioning is a black-box test technique that divides the input domain into partitions of equivalent data from which test cases can be derived1. In this case, the input domain is the combination of the number of consecutive hours studied and the average intensity of focus on the material during the study time. The partitions are the possible combinations of these two factors. There are four possible values for the number of hours studied (below 4 hours, 4 to 8 hours, 9 to 12 hours or above 12 hours) and three possible values for the intensity of focus (low, medium or high). Therefore, there are 12 possible partitions in total. The given test cases cover nine partitions, as shown in the table below:

The missing partitions are marked with a dash (-). To cover these partitions, three additional test cases are needed, such as:

TC9: Hours = 4 to 8, Intensity = High

TC10: Hours = 9 to 12, Intensity = Low

TC11: Hours = 9 to 12, Intensity = High

Correct : D

After completing the tool selection and a successful proof-of-concept, introducing the selected tool into an organization generally starts with a pilot project, which has the following objectives12:

Gaining in-depth knowledge about the tool, understanding both its strengths and weaknesses

Evaluating how the tool fits with existing processes and practices, and determining what would need to change

Assessing whether the benefits will be achieved at reasonable cost

Identifying and resolving any technical and organizational issues before deploying the tool on a larger scale

Providing training, coaching, and mentoring for users of the tool

Defining metrics to measure the success of the tool deployment

Therefore, the option D is the most typical objective of running a pilot project, as it is essential to ensure the compatibility and suitability of the tool with the current way of working, and to identify any potential risks or challenges that may arise from the tool introduction12.

The other options are not typical objectives of running a pilot project, because they are either part of the tool selection process, or the outcomes of the pilot project. They are:

To establish whether the tool is available for a free trial period (and for how long) (A).This is part of the tool selection process, which involves gathering information about the tool features, costs, support, and availability12.This should be done before running a pilot project, as it helps to narrow down the list of potential tools and to conduct a proof-of-concept12.

To provide training, coaching, and mentoring for users of the tool (B).This is an outcome of the pilot project, which aims to increase the competence and confidence of the tool users and to facilitate the tool adoption12.This should be done during and after the pilot project, as it helps to ensure the effective and efficient use of the tool and to address any issues or feedback from the users12.

To develop a clear set of requirements and objective criteria against which the tool can be evaluated .This is also part of the tool selection process, which involves defining the tool requirements based on the needs and expectations of the stakeholders, and establishing the evaluation criteria based on the benefits and risks of the tool12.This should also be done before running a pilot project, as it helps to compare and rank the potential tools and to select the most suitable one12.
