Test Analysis and Test Design · TA-3.2.3 Apply scenario-based testing
A Test Analyst is reviewing a use case for an online appointment booking system. The main success scenario describes a user successfully booking an appointment. An alternative scenario describes the user changing the appointment time before confirming. An exception scenario describes what happens if the selected time slot becomes unavailable just before confirmation.
Which test technique is most directly applicable for deriving test cases from this work product?
Show answer & explanation
Correct answer: C
Use cases are a primary input for scenario-based testing. This technique involves creating test cases that follow the paths (scenarios) through the use case, including the main success scenario, alternative paths, and exception paths. The goal is to verify the system's behavior in realistic, end-to-end user workflows.

Test Analysis and Test Design · TA-3.5.1 Select appropriate test techniques to mitigate product risks for a given situation
Case Study: AeroLogistics Freight Management System
AeroLogistics Inc. is upgrading its legacy freight management system to a modern, web-based platform. The new system handles international air freight shipments and involves complex business rules for pricing, customs declarations, and regulatory compliance. You are the lead Test Analyst responsible for ensuring the quality of the 'Shipment Pricing Engine' module.
The pricing engine calculates shipping costs based on a combination of factors: shipment weight, volume, origin, destination, freight type (e.g., general, perishable, hazardous), and customer priority level (e.g., standard, express). The business requirements document contains over 50 pages of complex, interdependent business rules. For example, 'If the freight type is hazardous AND the destination is in the EU, then a surcharge of 15% applies, unless the customer priority is express, in which case the surcharge is 20%.' Many such rules exist, and the risk of misinterpreting or incorrectly implementing this logic is identified as the highest product risk.
Early prototypes of the system have shown that the user interface for entering shipment details is stable, but the underlying calculations are prone to error. The development team is working in an iterative model, with new sets of pricing rules being delivered in each two-week sprint. The test team needs a systematic way to verify the complex logic and ensure full coverage of the business rules for each iteration.
Given the high-risk nature of the complex, interdependent business rules in the Shipment Pricing Engine, which test technique should be your primary choice to systematically design tests and achieve the highest level of rule coverage?
Show answer & explanation
Correct answer: C
The scenario explicitly describes a system governed by complex, interdependent business rules with multiple conditions leading to specific actions. This is the ideal situation for applying Decision Table Testing. This rule-based technique allows the Test Analyst to model all combinations of conditions in a structured table, identify any gaps or inconsistencies in the requirements, and derive a minimal set of test cases to cover every rule, thereby directly mitigating the highest identified product risk.

The Tasks of the Test Analyst in the Test Process · TA-1.3.3 Give examples of test environment requirements
A Test Analyst is tasked with specifying the test environment requirements for a new point-of-sale (POS) system that will be deployed in retail stores. The system must integrate with a variety of hardware devices.
Which of the following would be considered essential test environment requirements that the Test Analyst should specify? (Select TWO)
Show answer & explanation
Correct answers: A, D
Specifying the hardware components is a critical test environment requirement, as the POS system's functionality depends on correct integration with these devices.
The availability of external systems is a key aspect of the test environment. Specifying the need for a test double ensures that testing can proceed even if the live payment gateway is down or inaccessible, preventing blockages.
- Question 4Beginner
The Tasks of the Test Analyst in the Test Process · TA-1.3.6 Use keyword-driven testing to develop test scripts
True or False: When applying keyword-driven testing, the Test Analyst is typically responsible for implementing the low-level code that executes the action associated with a keyword like 'Login'.
Show answer & explanation
Correct answer: B
This statement is false. In keyword-driven testing, the Test Analyst's role is to identify and specify the business-facing keywords and use them to construct test scripts. The implementation of the underlying code for these keywords is typically the responsibility of a more technical role, such as a Technical Test Analyst (TTA) or a Test Automation Engineer (TAE).
- Question 5Advanced
Test Analysis and Test Design · TA-3.3.2 Apply metamorphic testing
A Test Analyst is testing an AI-based image recognition service that identifies species of birds from photographs. The underlying model is a complex neural network, and for a given input image, it is practically impossible to manually predict the exact confidence score for each of the thousands of possible bird species. This presents a significant test oracle problem.
Which test technique is specifically designed to address this type of test oracle problem by verifying properties of the output in relation to changes in the input?
Show answer & explanation
Correct answer: B
Metamorphic testing is ideal for situations with a test oracle problem. Instead of verifying a specific output, it checks for expected relationships (metamorphic relations) between the outputs of a series of related test cases. For example, if an image of a robin is slightly rotated (a change in input), the output should still identify it as a robin, perhaps with a slightly different confidence score (an expected property of the output). This verifies the system's behavior without needing to know the exact expected output for any single test.
- Question 6Intermediate
Test Analysis and Test Design · TA-3.2.1 Explain CRUD testing
A hospital's patient administration system manages patient records. A Test Analyst creates a CRUD matrix to verify the lifecycle of a 'Patient' entity.
Which of the following scenarios represents a test case for 'Consistency testing' within the CRUD testing technique?
Show answer & explanation
Correct answer: C
Consistency testing in CRUD is dynamic testing that verifies the correct interaction of functions handling an entity throughout its lifecycle. This option describes a test case that covers the full lifecycle (Create, Read, Update, Delete) and also includes negative testing (attempting to read a deleted entity) to ensure the entity is handled consistently across different operations.
- Question 7Intermediate
The Tasks of the Test Analyst in Risk-Based Testing · TA-2.2.1 Analyze the impact of changes to determine the scope of regression testing
A Test Analyst is analyzing the impact of a change in a tax calculation module to determine the scope of regression testing. The analyst uses a requirements traceability matrix that links requirements to test cases. The change affects requirement R-105. The matrix shows:
- R-105 is tested by TC-301 and TC-302.
- R-105 has a dependency on R-101, which is tested by TC-101.
- R-108, which is tested by TC-405, has a dependency on R-105.
Based on this impact analysis, which set of test cases represents the minimum scope for the regression suite?
Show answer & explanation
Correct answer: B
A thorough impact analysis for regression testing should include tests for the directly affected requirement (TC-301, TC-302), tests for requirements that have a dependency on the changed requirement (TC-405), and tests for requirements that the changed requirement depends on (TC-101). This ensures that both direct and indirect impacts (side effects) of the change are covered.
- Question 8Advanced
Test Analysis and Test Design · TA-3.2.2 Apply state transition testing
A Test Analyst is testing a document management system. The system's behavior for a document's status is modeled by the following state transition diagram. A test suite has been executed with the following test cases (sequences of states):
- TC1: Draft -> In Review -> Approved -> Published
- TC2: Draft -> In Review -> Rejected -> Draft -> In Review -> Approved -> Archived
- TC3: Draft -> In Review -> Approved -> Published -> Archived
What is the achieved level of 0-switch coverage (valid transitions coverage)?
stateDiagram-v2 [*] --> Draft Draft --> InReview : Submit InReview --> Approved : Approve InReview --> Rejected : Reject Rejected --> Draft : Revise Approved --> Published : Publish Approved --> InReview : Request Changes Published --> Archived : Archive Approved --> Archived : ArchiveShow answer & explanation
Correct answer: B
0-switch coverage is equivalent to valid transitions coverage. There are 8 valid transitions in the model: (1) Draft->InReview, (2) InReview->Approved, (3) InReview->Rejected, (4) Rejected->Draft, (5) Approved->Published, (6) Approved->InReview, (7) Published->Archived, (8) Approved->Archived.
- TC1 covers: 1, 2, 5.
- TC2 covers: 1, 3, 4, 2, 8.
- TC3 covers: 1, 2, 5, 7.
The covered transitions are {1, 2, 3, 4, 5, 7, 8}. The transition 'Approved -> InReview' (Request Changes) is NOT covered. Therefore, 7 out of 8 transitions are covered, which is 87.5%.
- Question 9Intermediate
Test Analysis and Test Design · TA-3.4.2 Prepare checklists that support experience-based testing
A Test Analyst is using a checklist to support experience-based testing of a web application's login form. The specification is minimal, but the analyst has experience with common vulnerabilities in such forms.
Which of the following items would be most appropriate to include in a 'do-confirm' checklist for this purpose?
Show answer & explanation
Correct answer: B
A 'do-confirm' checklist guides the thought process and provides ideas for exploration, rather than prescribing exact inputs. This option asks the tester to verify a quality attribute (resilience against SQL injection), prompting them to use their expertise to generate various specific attack strings. This is characteristic of a 'do-confirm' checklist, which is designed for experienced professionals.
- Question 10Beginner
The Tasks of the Test Analyst in the Test Process · TA-1.3.1 Differentiate between high-level test cases and low-level test cases
Which of the following BEST describes the difference between a high-level test case and a low-level test case?
Show answer & explanation
Correct answer: C
A high-level (or logical) test case describes what is being tested in abstract terms (e.g., 'Verify successful login with valid credentials'). A low-level (or concrete) test case provides the specific, concrete details needed for execution, including exact input data (e.g., username: 'testuser1', password: 'Password123') and the precise expected outcome.
