Which sequence of state transition stated in the answer choices is correct in accordance with the following figure depicting me life-cycle of a defect?

1. A. S0->S1->S2->S3->S4
2. B. S0->S1->S2->S3->S5^>S1
3. C. S0->S1->S2->S3->S5->S1->S2->S3
4. D. S0->S1->S2->S3->S5->S3->S4

Correct Answer: C
The figure depicts the life-cycle of a defect using state transition testing. State transition testing is a technique that models how a system transitions from one state to another depending on events or conditions. The figure shows six states (S0 to S5) and seven transitions (T0 to T6). The correct sequence of state transitions that follows the figure is S0->S1->S2->S3->S5->S1->S2->S3. This sequence represents the following scenario:
✑ S0: The defect is not yet detected (initial state).
✑ T0: The defect is detected by testing (event).
✑ S1: The defect is reported and registered (state).
✑ T1: The defect is assigned to a developer for fixing (event).
✑ S2: The defect is being fixed by the developer (state).
✑ T2: The developer fixes the defect and delivers a new version (event).
✑ S3: The defect is verified by testing (state).
✑ T5: The testing fails to confirm that the defect is fixed (event).
✑ S5: The defect is rejected by testing (state).
✑ T6: The defect is reassigned to a developer for fixing (event).
✑ S1: The defect is reported and registered (state).
✑ T1: The defect is assigned to a developer for fixing (event).
✑ S2: The defect is being fixed by the developer (state).
✑ T2: The developer fixes the defect and delivers a new version (event).
✑ S3: The defect is verified by testing (state). The other sequences are incorrect, as they do not follow the transitions shown in the figure. Verified References: [A Study Guide to the ISTQB® Foundation Level 2018 Syllabus - Springer], Chapter 4, page 40-41.

Which of the following CORRECTLY matches the roles and responsibilities in a formal review?

1. A. Facilitator - Fixes defects in the work product under review
2. B. Scribe - Collates potential defects found during the individual review activity
3. C. Review Leader - Creates the work product under review
4. D. Author - Identify potential defects in the work product under review

Correct Answer: B
In formal reviews, the scribe's role is to collate potential defects and other findings during the review process. This position is crucial as it ensures all observations and defects are recorded accurately, facilitating efficient analysis and resolution of issues identified during the review.References:ISTQB Certified Tester Foundation Level Syllabus v4.0, Section 3.2.4 "Roles and Responsibilities in a Formal Review".

The following 4 equivalence classes are given:

Which of the following alternatives includes correct test values for x. based on equivalence partitioning?

1. A. -100; 100:1000; 1001
2. B. -500; 0; 100; 1000
3. C. -99; 99:101; 1001
4. D. -1000; -100; 100; 1000

Correct Answer: D
✑ The question is about selecting the correct test values for x based on equivalence partitioning. Equivalence partitioning is a software test design technique that divides the input data of a software unit into partitions of equivalent data from which test cases can be derived. In this case, the given equivalence classes are:
Option D provides a value from each of these partitions:
✑ For (x \leq -100), it gives -1000.
✑ For (-100 < x>✑ For (100 \leq x < 1000>✑ For (x \geq 1000), it gives 1500.
So, option D covers all four given equivalence classes with appropriate values. References: ISTQB Certified Tester Foundation Level (CTFL) v4.0 documents available at ISTQB and ASTQB.

Which of the following statements BEST describes how test cases are derived from a use case?

1. A. Test cases are derived based on non-functional requirements such as usability
2. B. Test cases are created using white-box test techniques to execute scenarios of use cases
3. C. Test cases are derived based on pair testing between a user and a tester to find defects
4. D. Test cases are designed to cover various user behaviors, including basic, exceptional oralternative and error behaviors associated with human users or systems

Correct Answer: D
Use cases describe a system's behavior as it responds to a request from a user. They typically consist of various scenarios, such as basic flow, alternative flow, and exceptional flow, which represent possible behaviors when a user interacts with the system. When deriving test cases from use cases, it is important to cover these different types of user behaviors.Test cases should be designed to verify how the system behaves during each of these scenarios. This ensures that the system operates correctly for normal and error conditions encountered by human users or systems interacting with the application. Thus, test cases derived from use cases aim to cover basic, exceptional, and alternative flows, ensuring comprehensive coverage.References:

Which of the following is a possible reason for introducing a defect in software code?

1. A. Rushing to meet a tight deadline to turn code over for testing
2. B. Improper unit testing
3. C. Improper system testing
4. D. Focus on static testing over dynamic testing

Correct Answer: A
The ISTQB CTFL syllabus identifies several causes for defects in software. One prominent reason, as highlighted in the curriculum, is the pressure and rush to meet tight deadlines, which can lead to insufficiently reviewed or tested code being moved into further stages of testing or production. This scenario describes rushing to meet a deadline as a potential cause for defects because it may compromise the thoroughness of code development and testing.References:ISTQB Certified Tester Foundation Level Syllabus v4.0, Section 1.4.1 "Why is Testing Necessary?".
