ISTQB-CTFL ISTQB Certified Tester Foundation Level (CTFL v4.0) Free Practice Exam Questions (2025 Updated)

Entry and exit criteria are used to determine when to start and stop testing, respectively.

Entry Criteria:

These are conditions that should be met before testing begins.

Examples:

2. The test automation tool has been installed and properly configured

4. The performance test environment has been set-up and is available

5. The user stories have proper acceptance criteria defined

Exit Criteria:

These are conditions that should be met before testing concludes.

Examples:

1. A defined level of code coverage has been achieved

3. The number of unresolved defects is within the predefined limit

6. The testing budge​ (ISTQB not-for-profit association)​ spent and the project sponsor bears the risk of not testing any further

According to the ISTQB Certified Tester Foundation Level (CTFL) v4.0 syllabus, these criteria help in effectively managing the testing process【6†source】.

Testware is a term that refers to all artifacts produced during the testing process, such as test plans, test cases, test scripts, test data, test results, defect reports, etc. The following statements about testware are correct:

II) All the testware should be subject to Configuration Management. Configuration management is a process that establishes and maintains consistency among work products throughout their life cycle. Configuration management applies to all testware, as it helps ensure their quality and consistency, track their changes and defects, control their versions and access rights, and link them to other artifacts.

III) The testware at the end of the project should be transferred to the organization responsible for maintenance. Maintenance testing is testing performed on a software product after delivery to correct defects or improve performance or other attributes. Maintenance testing requires testware from previous testing activities or phases, such as test cases, test data, test results, etc. Therefore, the testware at the end of the project should be transferred to the organization responsible for maintenance testing, such as support team or maintenance team. The following statements about testware are incorrect:

I) When closing the test activities, all the testware resources can be uninstalled and released. This statement is incorrect, as some testware resources may still be needed for future testing activities or phases, such as maintenance testing or regression testing. Therefore, when closing the test activities, some testware resources should be archived and stored for future use, while others can be uninstalled and released.

IV) The developers are responsible for the correct installation of the testware. This statement is incorrect, as the testers are responsible for the correct installation of the testware. The testers should ensure that they have access to all necessary testware resources and that they are installed and configured properly before starting the test execution.

Static testing, such as code reviews and static analysis, is particularly effective at identifying issues related to code structure and modularization. These techniques allow for the inspection of the code without executing it, making it easier to spot problems related to how the code is organized. Dynamic testing, on the other hand, focuses on the execution of code and is better suited for identifying runtime issues but does not easily reveal structural problems. The ISTQB CTFL Syllabus v4.0 highlights the strengths of static testing in uncovering such structural issue

A unit test framework tool is a tool that supports the creation, execution, and reporting of unit tests, which are tests that verify the functionality and quality of individual software components (such as functions or methods) in source code. A unit test framework tool can help to detect defects in functions or methods in source code by providing features such as test case generation, test case execution, test result comparison, test coverage measurement, etc. Some examples of unit test framework tools are JUnit, NUnit, TestNG, etc. The other options are not tools that are likely to detect defects in functions or methods in source code. A configuration management tool is a tool that supports the management and control of different versions and variants of software products or components. A test design tool is a tool that supports the design and generation of test cases based on some criteria or rules. A monitoring tool is a tool that monitors the behavior or performance of a system or component under test.

Comprehensive and Detailed In-Depth Explanation:

The primary objectives of testing, as outlined in the ISTQB CTFL v4.0 syllabus, include verifying whether specified requirements are met (A), detecting failures and defects (B), and validating that the test object functions as expected (D). However, "finding errors" (C) is not a direct objective. Errors result from human mistakes, but testing primarily identifies defects, which are flaws in the system that cause failures. Testing aims to reveal defects rather than directly identify errors in the code.

The correct statement is B. According to the ISTQB CTFL syllabus, the testing quadrants help to categorize tests based on their purpose and whether they are technology-facing or business-facing, and whether they support the team or critique the product. Quadrant Q2 includes tests that are business-facing and support the team, such as automated acceptance tests produced during Behavior-Driven Development (BDD) and Acceptance Test-Driven Development (ATDD)​​ .

Quadrant Q3 includes business-facing tests that critique the product, such as exploratory testing, usability testing, and user acceptance testing. These tests are typically manual and focus on evaluating the product from a user perspective, rather than being part of a continuous integration process​​.

Quadrant Q4 includes technology-facing tests that critique the product, such as performance tests, security tests, and other non-functional tests, which can be automated but are not related to unit tests produced during TDD .

For executive-level employees, a test summary report should be concise and focus on high-level information. It typically includes a summary of defects categorized by priority or budget. Executives are generally interested in the overall status and the impact on critical business objectives rather than detailed technical information. The report should provide an overview of the most important aspects of testing, such as key issues, test progress, and any risks or concerns that could affect project outcomes.

The correct matching of the topics with their descriptions is as follows:

Functional behaviour: The externally observable behaviour with user actions as input operating under certain configurations (A to C).

Quality characteristics: How the system performs the specific behaviour (B to A).

Scenarios: A sequence of actions between an external actor and the system, to accomplish a specific goal or business task (C to B).

Business rules: Activities that can only be performed in the system under certain conditions defined by outside procedures and constraints (D to E).

External interfaces: Description of the connections between the system to be developed and the outside world (E to D)​​.

Comprehensive and Detailed In-Depth Explanation:

Static analysis requires access to work products like source code, models, or documentation, making it impossible to analyze Commercial off-the-shelf (COTS) software (A) because its source code is typically unavailable. Static analysis is applicable to source code (B), BPMN models (C), and UML diagrams (D).

Analyzing and removing the cause of failures is not an objective of testing, but rather a task of development or maintenance. A failure is an event or behavior that deviates from the expected or specified result of a system under test. A failure is caused by an error (also known as a mistake or a fault) in the software code, design, or specification. Analyzing and removing the cause of failures is a process of locating and fixing errors in the software code, design, or specification, which is also known as debugging or defect resolution. Analyzing and removing the cause of failures does not aim to find or report defects, but rather to correct or prevent them. The other options are objectives of testing. Finding defects is one of the main objectives of testing, as it helps to improve the quality and reliability of the software product. Providing information for decision-making is another objective of testing, as it helps to support decision making and risk management. Gaining confidence about the level of quality of the software is another objective of testing, as it helps to assure that the software product meets its requirements and customer or user needs and expectations.

The fundamental testing process includes activities that are directly related to the planning, preparation, execution, and evaluation of tests, as well as the closure activities of the testing phase. Option D, "Build release and maintenance," falls outside the scope of the fundamental testing process as it relates more to software development and operations rather than specific testing activities. Options A, "Archiving automation code," B, "Test status reporting," and C, "Test process improvement," are all activities that can be part of or associated with the fundamental testing process. Archiving automation code is part of test closure, test status reporting is part of test monitoring and control, and test process improvement can be an outcome of test closure activities.

Matching the descriptions with the test techniques:

Black-box test techniques use the external description of the software, including requirements, use cases, and user stories.

White-box test techniques use the internal structure of the software system, including software architecture and code.

Black-box test techniques can reveal deviations from the requirements as they validate the external behavior of the software.

Both black-box and white-box test techniques are applicable to functional and non-functional testing.

Effort estimate does not depend on the budget of the project, but rather on the scope, complexity, and quality of the software product and the testing activities1. Budget is a constraint that may affect the feasibility and accuracy of the effort estimate, but it is not a factor that determines the effort estimate. Effort estimate is the amount of work required to complete the testing activities, measured in terms of person-hours, person-days, or person-months2.

The other options are correct because:

A. Once the test effort is estimated, resources can be identified and a schedule can be drawn up, as they are interrelated aspects of the test planning process3. Resources are the people, tools, equipment, and facilities needed to perform the testing activities4. Schedule is the time frame and sequence of the testing activities, aligned with the project milestones and deadlines5.

B. Effort estimate can be inaccurate because the quality of the product under tests is not known, as it affects the number and severity of the defects that may be found and the rework that may be needed to fix them6. Quality is the degree to which the software product satisfies the specified requirements and meets the needs and expectations of the users and clients7.

D. Experience based estimation is one of the estimation techniques, which relies on the judgment and expertise of the testers and other project stakeholders to estimate the test effort based on similar projects or tasks done in the past. Experience based estimation can be useful when there is a lack of historical data, formal methods, or detailed information about the software product and the testing activities.

When scheduling test cases, priorities and dependencies must be considered. The best execution order will respect both the logical dependencies and the priorities assigned to each test case.

Given the options, the correct order considering the priorities and dependencies is:

TC1 (Priority 1)

**TC​ (ISTQB not-for-profit association)​ity 2, dependent on TC1)

TC2 (Priority 3, dependent on TC1)

TC4 (Priority 4)

TC5 (Priority 5)

TC6 (Priority 6, dependent on TC4)

According to the ISTQB Certified Tester Foundation Level (CTFL) v4.0 syllabus, understanding dependencies and scheduling tests accordingly is crucial for effective test execution【6†source】.
