Comprehensive and Detailed in Depth Explanation:

Portability testing verifies that software can be transferred from one environment to another with minimal effort. It checks for installation, adaptation, and replacement issues.

a) Insufficient, unclear installation or de-installation instructions:This directly relates to portability because improper installation procedures can affect moving the software to different environments.

e) The stock control barcodes cannot be read by the replaced barcode scanner:This issue is associated with compatibility and adaptability between devices, which is crucial in portability testing.

Optionsb) and d)relate to usability and performance testing, not portability.

Optionc)relates to security or access control testing.

Therefore, the correct answer isA (a, e).

Comprehensive and Detailed In-Depth Explanation:

A (Exploratory testing):Useful for investigating new areas, but not suitable for structured role-based testing.

B (Use Case testing):Correct. This technique focuses on how different user roles interact with the system, ensuring it meets their expectations and usability needs.

C (Pairwise testing):Efficient for combinations of input values, but irrelevant to role-based UI testing.

D (Boundary Value Analysis):Focuses on numeric boundaries, not applicable for role-specific usability.

Therefore, the correct answer isB (Use Case testing).

Classification trees support the application of pairwise testing in the following ways:

a. They help to identify inputs to be used by the pairwise test technique - This is true because classification trees show the classes and subclasses of inputs for a given scenario in a graphical way.

b. They show the combinations needed to cover all-pairs - This is true because classification trees can be used to generate the combinations of inputs that cover all pairs using a mathematical algorithm.

c. They help to identify particular combinations of interest - This is true because classification trees can be used to highlight or prioritize certain combinations of inputs that are more relevant or important for the scenario.

d. They show both typical and atypical behavior - This is false because classification trees do not show the behavior or the expected results of the system under test, only the inputs and outputs.

e. They show the expected results for the various test cases - This is false because classification trees do not show the expected results or the verification criteria for the test cases, only the inputs and outputs.

The risk impact for requirement R1 should be categorized as high or very high, as it is a business critical requirement that affects the core functionality of the system. The risk impact is determined by assessing the potential negative consequences of a failure or defect in the system. The other statements are not true, as they are based on assumptions or irrelevant factors. Verified References: [ISTQB® Certified Tester Advanced Level Test Analyst CTAL-TA], Section 1.2.1, page 13.

Comprehensive and Detailed in Depth Explanation:

Pairwise testing is a combinatorial test design technique in which test cases are designed to execute all possible discrete combinations of each pair of input parameters. This technique significantly reduces the number of test cases compared to exhaustive testing while still covering pairwise interactions.

To calculate the number of test cases:

Colour: 4 options

Model: 3 options

Gigabytes: 4 options

Connectivity: 2 options

Pairwise testing does not necessarily involve multiplying all options, as it aims to cover all pairs. Using an orthogonal array or pairwise tool, the minimum number of test cases that cover all pairs for these parameters is16. Hence, the answer isC (16).

Analysing anomalies to establish their likely causes is an appropriate task for the Test Analyst to perform during the test execution phase, as it involves applying defect analysis techniques to identify the root causes of defects and suggest possible solutions. Creating a test execution schedule, creating automated tests, and finalizing test data and test environments are tasks that belong to other phases of testing, such as test planning, test implementation, and test preparation.

Comprehensive and Detailed In-Depth Explanation:

Since the failure occurred when using anew keyword, the most logical first step is to involve theTechnical Test Analystto review the keyword script. This is because the issue may lie in the implementation or integration of the new keyword within the automated framework.

Option A:Investigating the test sequence is important but not the first step when the problem clearly points to the new keyword.

Option B:Removing the test case without identifying the root cause is not a recommended practice.

Option C:Manually executing the test without analyzing the automation script does not address the potential problem in the keyword itself.

Option D:Since the problem is linked to a new keyword, it makes sense to review the keyword script first.

Therefore, the correct answer isD (Ask the technical test analyst to review the keyword script(s)).

Eight 0-switch test cases are needed to achieve 100% 0-switch coverage. A state transition test technique is a technique that tests the behavior of a system or component based on its states and transitions between them. A 0-switch test case is a test case that covers one state and its associated actions and events. To achieve 100% 0-switch coverage, all states and their associated actions and events must be covered by at least one test case. The states for this scenario are:

Enter PIN

PIN OK

PIN not OK

1st try

2nd try

3rd try

Access to act

Eat card

The technique that is most likely to support the required functional correctness testing is state transition testing. State transition testing is a technique that tests the behavior of a system or component based on its states and transitions between them. This technique is suitable for testing a system that has different modes or states depending on the input values or events, such as a car navigation system.

Comprehensive and Detailed in Depth Explanation:

To determine the number of test cases, we follow the coverage rules:

Basic Behavior:One test case for the standard check-in process without errors (1 test case).

Error Handling (Exceptions):There are 7 exceptions listed (E1 to E7), and each needs a separate test case.

Hence, the total number of test cases is1 (basic) + 7 (error scenarios) = 8.

Therefore, the correct answer isB (8).
