ISTQB-CTAL-TA Exam Dumps - ISTQB Certified Tester Advanced Level - Test Analyst (CTAL-TACore)v3.1.2

The checklist item that would result in finding a defect for the user story is “Are the acceptance criteria defined and testable?”. The acceptance criteria are the conditions that a system or component must satisfy in order to be accepted by a user, customer, or other authorized entity. The acceptance criteria should be defined and testable for each user story, as they provide the basis for designing and executing test cases. The user story in this question does not have any acceptance criteria defined, which is a defect that needs to be addressed.

The type of document that is typically used by a Test Analyst as the test basis for interoperability testing is the system architecture document. The system architecture document describes the structure and behavior of the system under test and its components, as well as their interactions and dependencies with other systems or components. This document can provide information about the interfaces and protocols that need to be tested for interoperability.

Comprehensive and Detailed in Depth Explanation:

Since the question focuses onIterations 1 and 2 only, we must prioritize risks related to these iterations.

R01(Accessibility): Low likelihood, medium impact — not a priority for initial iterations.

R02(Budget calculation): Related to Iteration 3, so it isnot relevantto the current test design.

R03(Installation issues on iOS and Android): High impact, medium likelihood —relevantfor both Iterations 1 and 2. Installation is crucial for ensuring the application works on both platforms.

R04(Insufficient testing time): Medium impact and likelihood — important, but R03 is more critical.

Hence, the highest priority risk to address first isR03 (The application may be incorrectly installed on some iOS and Android devices).

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

Comprehensive and Detailed in Depth Explanation:

Functional appropriateness testingis often done duringsystem testingbecause it evaluates whether the implemented functions meet user needs, but it can also be part ofintegration testingwhen assessing integrated components.

Functional correctness testingisnot limited to any specific test level. It can be performed duringunit, integration, system, or acceptance testingto verify the accuracy of functions.

Option Bis incorrect because functional completeness is not necessarily the last stage of testing.

Option Cis incorrect because functional appropriateness is mainly done during system testing, not before.

Option Dis incorrect because functional correctness is not restricted to system testing.

The correct answer isA (Functional appropriateness testing is usually undertaken during system testing; functional correctness testing can be conducted at any test level).
