Which or the following is a valid collection of equivalence classes for the following problem: An integer field shall contain values from and including 1 to and including 15.

1. A. Less than 0.1 through 14. 15 and more
2. B. Less than 1.1 through 14. more than 15
3. C. negative number
4. D. 1 through 15. above 15
5. E. Less than 1.1 through 15. more than 15

Correct Answer: D
Equivalence partitioning is a black-box test design technique where inputs to the software or system are divided into groups that are expected to exhibit similar behavior. For an integer field that should accept values from 1 to 15, the valid equivalence class is 1 through 15. The invalid equivalence classes are numbers less than 1 and numbers more than 15. Therefore, option D, "Less than 1, 1 through 15, more than 15," correctly identifies the valid equivalence class along with the two invalid classes, covering all possible input scenarios for the field. Options A, B, and C either do not accurately capture the valid range or incorrectly specify the range boundaries.

Which of the following tasks is MOST LIKELY to be performed by the tester?

1. A. Develop a test strategy and test policy for the organization
2. B. Promote and advocate the test team within the organization
3. C. Create the detailed test execution schedule
4. D. Introduce suitable metrics for measuring test progress

Correct Answer: C
Testers are typically involved in creating detailed test execution schedules, among other tasks such as designing tests, executing tests, and logging defects. Creating a test strategy and test policy, promoting and advocating the test team, and introducing metrics are typically responsibilities of test managers or senior roles.
In the ISTQB Certified Tester Foundation Level (CTFL) v4.0 syllabus, the responsibilities of testers include creating test cases, setting up test (ISTQB not-for-profit association)nts, executing tests, and reporting defects, which align with creating detailed test execution schedules6†source.

Which of the following statements is LEAST likely to be describing component testing?

1. A. It identifies defects in modules and classes.
2. B. Simulators and stubs may be required.
3. C. It mainly tests interfaces and interaction between components.
4. D. It may be applied using a test-first approach.

Correct Answer: C
Component testing (also known as unit testing or module testing) is a level of testing that focuses on verifying the functionality and quality of individual software components (such as modules, classes, functions, methods, etc.). Component testing mainly tests interfaces and interaction between components, as well as internal logic and data structures of the components. Component testing may be applied using a test-first approach (such as test-driven development or behavior-driven development), where tests are written before the code is implemented. Component testing does not identify defects in modules and classes, as this is a result of component testing, not an objective. Simulators and stubs may be required for component testing, as they can simulate or replace missing or incomplete components or external systems that are needed for testing.

Software was found lo take much more time than the stated requirement of less than one
second to save a file. Upon investigation it was found that there was an unnecessary check inside a loop which was slowing down the file-save operation. The software not being able to meet the desired response time is an example of

1. A. It is not a defect
2. B. Defect
3. C. Error
4. D. Failure

Correct Answer: D
A failure is an event in which a component or system does not perform a required function within specified limits. A failure is observable by the software users or other stakeholders. A failure is caused by one or more defects in the software. In this case, the software not being able to meet the desired response time is an example of a failure, as it deviates from the stated requirement and affects the user experience. It is not a defect, which is a flaw in the software that causes the failure. It is not an error, which is a human action that produces an incorrect result. It is not a non-defect, as it clearly violates a specified requirement. Verified References: [A Study Guide to the ISTQB® Foundation Level 2018 Syllabus - Springer], Chapter 1, page 4.

Which of the following is a correct reason to apply test automation?

1. A. When a new test automation tool is launched
2. B. When there are a lot of repetitive testing tasks
3. C. When it is easy to automate
4. D. When it is cheap to buy test automation tools

Correct Answer: B
A correct reason to apply test automation is when there are a lot of repetitive testing tasks. Test automation is the use of software tools or scripts to perform or support testing activities, such as test case execution, test result comparison, test data generation, etc. Test automation can be beneficial when there are a lot of repetitive testing tasks that need to be performed frequently or consistently, such as regression testing, performance testing, load testing, etc. Test automation can help to save time and effort, increase reliability and accuracy, and improve coverage and efficiency of testing. The other options are not correct reasons to apply test automation. When a new test automation tool is launched is not a reason to apply test automation, but rather a factor for choosing a test automation tool. When it is easy to automate is not a reason to apply test automation, but rather a factor for evaluating the feasibility of test automation. When it is cheap to buy test automation tools is not a reason to apply test automation, but rather a factor for estimating the cost and benefit of test automation.
