Question 1

A test case starts at S1 and triggers 4 events in sequence: E1, E4, E5, E7. What will be the finishing state and the output(s) from the test case? [K3]

Refer to the exhibit

Answer Options
Correct Answer: D
Explanation

S2 and O2 are the finishing state and the output(s) from the test case1. The question asks about a test case that starts at S1 and triggers 4 events in sequence: E1, E4, E5, E7. The question refers to a state diagram that shows the logic of a system with six states (S1, S2, S3, S4, S5, S6) and seven events (E1, E2, E3, E4, E5, E6, E7). The state diagram also shows four outputs (O1, O2, O3, O4) that are produced by some events. The state diagram is shown below:

!state diagram

To answer this question, we need to follow the path of the test case on the state diagram and observe the state transitions and outputs that occur. The path of the test case is:

Start at S1

Trigger E1

Transition to S2

Trigger E4

Transition to S3

Trigger E5

Transition to S2

Output O2

Trigger E7

Transition to S6

Therefore, the finishing state of the test case is S2 and the output(s) from the test case is O2. Hence, D is the correct answer.

Question 2

Which of the following are correct tasks during "Test analysis and design"?

I, Designing and prioritizing test cases

II, Identifying any required infrastructure and tools

II,I, Reviewing the test basis

IV Creating test data and preparing test harnesses

V, Writing automated test scripts

Answer Options
Correct Answer: C
Explanation

Test analysis and design is the phase of the test process where test cases and test data are designed and prioritized, based on the test basis and test objectives. Therefore, option C is correct, as it includes tasks I, II, and II,I, Option A is incorrect, as it includes tasks IV and V, which are part of test implementation and execution phase. Option B is incorrect, as it includes task IV, which is part of test implementation and execution phase. Option D is incorrect, as it does not include task II,I, which is part of test analysis and design phase.

Question 3

For the code fragment given below, which answer correctly represents minimum tests required for statement and branch coverage respectively?

Answer Options
Correct Answer: D
Explanation

For the code fragment given below, one test case is required for statement coverage and two test cases are required for branch coverage. Statement coverage requires that every executable statement in the code is executed at least once. Branch coverage requires that every possible outcome of each decision point in the code is executed at least once. The following table shows how to achieve statement and branch coverage for the code fragment:

Test Case

Input

Output

Statement Coverage

Branch Coverage

1

x = 3

y = 9

S1, S2, S3

T1 = true

2

x = 5

y = 25

S1, S2

T1 = false

As shown in the table, test case 1 covers all three statements (S1, S2, S3) in the code fragment, achieving 100% statement coverage. Test case 2 covers only two statements (S1, S2) in the code fragment, but it exercises a different outcome of the decision point T1 (if x < 4), achieving 100% branch coverage.

Question 4

Which of the following would be LEAST appropriate as part of an incident report covering the observation of a failure during testing?

Answer Options
Correct Answer: B
Explanation

The user interface being complicated and confusing is not an appropriate part of an incident report covering the observation of a failure during testing, as it is a subjective opinion and not a factual description of the failure.An incident report should include objective and relevant information that can help to identify, reproduce, and resolve the failure3defines an incident report as follows:

An incident report is a document that records the occurrence of an abnormal or unexpected event during testing, such as a deviation from expected results, a defect in the system under test, or a problem in the test environment. An incident report typically includes the following information:

Identifier: A unique identifier for the incident report.

Summary: A brief description of the incident.

Incident details: A detailed description of the incident, including the inputs, expected results, actual results, environment, date and time, severity, priority, and any other relevant information.

Steps to reproduce: A sequence of steps that can be followed to reproduce the incident.

Attachments: Any screenshots, logs, files, or other artifacts that can help to understand or reproduce the incident.

Question 5

What are metrics NOT used for?

Answer Options
Correct Answer: C
Explanation

To apply to the RAD development model. Metrics are quantitative measures that can be used to monitor, control, and improve the test process and the quality of the system. Metrics can be used for various purposes, such as to identify the percentage of work done in test environment preparation or test case preparation, to measure whether dates of test milestones were met, to compare actual results with expected results, to evaluate the effectiveness and efficiency of testing, etc. However, metrics are not specific to any development model, such as RAD (Rapid Application Development), and can be applied to any type of software development project. A detailed explanation of metrics can be found in [A Study Guide to the ISTQB Foundation Level 2018 Syllabus], pages 103-105.
