CTFL_Syll_4.0 iSQI ISTQB Certified Tester Foundation Level (CTFL) v4.0 Free Practice Exam Questions (2025 Updated)

The tool described in the question supports the automated creation and installation of builds and the execution of various types of automated tests. This aligns with the practices and tools typically found in DevOps environments, which aim to integrate and automate the processes between software development and IT teams. DevOps tools facilitate continuous integration (CI) and continuous delivery (CD), enabling automated building, testing, and deployment of applications. Therefore, the correct answer is that this is an example of DevOps related tools​​.

This answer is correct because static testing and dynamic testing are both types of testing that can be used to highlight issues associated with non-functional characteristics, such as usability, performance, security, reliability, etc. Static testing is a type of testing that involves the analysis of software work products, such as requirements, design, code, or test cases, without executing them. Dynamic testing is a type of testing that involves the execution of software work products, such as code or test cases, using inputs and verifying outputs. Both static testing anddynamic testing can be applied to different test levels and test types, and can use different test techniques and tools, to evaluate the non-functional characteristics of the software product. References: ISTQB Glossary of Testing Terms v4.0, ISTQB Foundation Level Syllabus v4.0, Section 2.2.1.1, Section 2.2.1.2

In the ISTQB terminology:

A defect (also known as a bug or fault) is an issue in the code that can cause a failure.

A failure is the observable incorrect behavior or output of the software due to a defect.

In this scenario, the memory leak is the defect in the application code that causes the application not to release dynamically allocated memory properly. The observable effect of this defect, which is the slowdown in response time, is considered a failure because it is the manifestation of the defect that prevents the application from meeting its performance requirements.

In a structured review process, it is essential to plan reviews carefully and manage them effectively. Reviewing large work products in one go is not recommended because it can lead to oversight of issues due to fatigue or information overload. It is more efficient to break down large work products into smaller, manageable parts and review them incrementally. This ensures a thorough and effective review process. Additionally, other practices such as planning for the review, starting discussions during review initiation, and creating defect reports for found issues are standard recommendations for an effective review process​​.

The testing quadrants, as defined in the context of agile testing, help categorize different types of tests based on their goals and who they serve.

Q1:Technology-facing tests that support the team (e.g., unit tests).

Q2:Business-facing tests that support the team (e.g., automated acceptance tests, BDD, ATDD).

Q3:Business-facing tests that critique the product (e.g., exploratory testing).

Q4:Technology-facing tests that critique the product (e.g., performance and load tests).

Option B correctly places automated acceptance tests from BDD and ATDD in quadrant Q2.

Statement coverage, also known as line coverage, is a metric used in white-box testing to measure the percentage of executable statements in the source code that have been executed by the test suite. Achieving a certain percentage of statement coverage means that an equivalent percentage of the executable statements in the code have been executed during testing.

For example, achieving 80% statement coverage indicates that 80% of the lines of code have been run through during the testing process. This metric helps in identifying parts of the code that have not been tested and may contain undetected defects.

It's important to note that achieving high statement coverage does not necessarily guarantee that all possible paths or scenarios within the code are tested, nor does it ensure the detection of all types of defects. Other coverage metrics, such as branch coverage or condition coverage, might also be necessary to achieve a more thorough testing process.

The testing of software does not demonstrate the absence of defects, but rather the presence of defects or the conformance of the software to the specified requirements1. Testing can never prove that the software is defect-free, as it is impossible to test all possible scenarios, inputs, outputs, and behaviors of the software2. Testing can only provide a level of confidence in the quality of the software, based on the coverage, effectiveness, and efficiency of the testing activities3.

The other options are correct because:

A. Properly designed tests that pass reduce the level of risk in a system, as they verify that the system meets the expected quality attributes and satisfies the needs and expectations of the users and clients4. Risk is the potential for loss or harm due to the occurrence of an undesirable event5. Testing can help to identify, analyze, prioritize, and mitigate the risks associated with the software product and project6.

C. Software testing identifies defects, which can be used to improve development activities, as they provide feedback on the quality of the software and the effectiveness of the development processes7. Defects are flaws or errors in the software that cause it to deviate from the expected or required results or behavior. Testing can help to detect, report, track, and resolve the defects, and prevent them from recurring in the future.

D. Performing a review of the requirement specifications before implementing the system can enhance quality, as it can ensure that the requirements are clear, complete, consistent, testable, and aligned with the needs and expectations of the users and clients. Requirements are the specifications of what the software should do and how it should do it. Testing can help to validate that the requirements are met by the software, and verify that the software is implemented according to the requirements.

Comprehensive and Detailed Explanation From Exact Extract:

“Confirmation testing confirms that an original defect has been successfully fixed… Regression testing confirms that no adverse consequences have been caused by a change… These adverse consequences could affect the same component where the change was made, other components in the same system, or even other connected systems.”

(ISTQB CTFL Syllabus v4.0, Section 2.2.3 – Confirmation Testing and Regression Testing, Page 30)

The test leader is the person who is responsible for planning, monitoring, and controlling the test activities and resources in a test project. The test leader should have the best knowledge of the test objectives, scope, risks, resources, schedule, and quality criteria. The test leader should also be aware of the test automation criteria, such as the execution frequency, the test support, the team education, the roles and responsibilities, and the devs and testers collaboration1. Based on these factors, the test leader can decide which tests are suitable for automation and which are not, and prioritize them accordingly. The test leader can also coordinate with the test automation engineers, the developers, and the stakeholders to ensure the alignment of the test automation strategy with the test project goals and expectations. References = ISTQB Certified Tester Foundation Level (CTFL) v4.0 Syllabus, Chapter 2, Section 2.3.1, Page 152; ISTQB Glossary of Testing Terms v4.0, Page 403; ISTQB Certified Tester Foundation Level (CTFL) v4.0 Syllabus, Chapter 6, Section 6.1.1, Page 514; Top 8 Test Automation Criteria You Need To Fulfill - QAMIND1

One of the typical potential risks associated with using test automation tools is the underestimation of the effort required to maintain test scripts. While test automation can reduce test execution times and provide more consistent and repeatable tests compared to manual testing, maintaining test scripts can be labor-intensive and often requires significant effort. Changes in the application under test can lead to frequent updates in the test scripts to keep them functional and relevant.

In the ISTQB CTFL Syllabus, it is stated that a key objective of testing is to verify that the test object meets regulatory requirements. This is crucial as compliance with regulatory standards ensures that the software adheres to necessary laws, guidelines, and safety standards which are often mandatory in various industries such as healthcare, finance, and aviation. Ensuring regulatory compliance helps prevent legal issues and promotes user safety and trust.

Independent testers provide a fresh perspective and are more likely to identify failures that developers might overlook due to their familiarity with the software (C). Independent testing helps avoid cognitive biases, improves defect detection, and enhances the overall quality assurance process. While A and D touch on related concepts, they do not directly define the benefit as well as C does. Option B highlights a potential challenge rather than a benefit.

This answer is correct because it follows the logical dependencies and allows executing the test cases in priority order. TC4, TC3, and TC2 are executed first because they have the highest priority. TC6 is executed next because it has a logical dependency on TC2. TC1 is executed next because it has a logical dependency on TC5. Finally, TC5 is executed last because it has the lowest priority. References: ISTQB Certified Tester Foundation Level (CTFL) v4.0 documents

Checklist-based testing, as defined in the ISTQB CTFL syllabus, is indeed a review technique used within formal review processes. During these reviews, reviewers individually inspect work products to identify defects based on predefined checklists. These checklists serve as guidelines to ensure thorough examination and to cover important aspects consistently.

The other options do not accurately describe the checklist-based testing technique. Option A describes a technique for managing review meetings rather than the checklist-based testing itself. Option C incorrectly emphasizes the level of detail in checklists as a factor in reproducibility of test cases, which is not the primary focus of checklist-based testing. Option D, while true about the necessity of periodic review, is not the core aspect of the checklist-based testing technique itself.

Equivalence partitioning (EP)divides input values into classes where test casesrepresent all possible valuesof each partition. The partitions in this scenario are:

≤7 (too cold → W)

8-21 (standstill → X)

22-29 (ideal → Y)

≥30 (too hot → Z)

OptionC ({7,10,25,29})covers all partitionsby selecting representative values:

7 → Too cold (W)

10 → Standstill (X)

25 → Ideal (Y)

29 → Upper boundary of ideal (Y)

Other options do not cover all partitions adequately.

In the given state transition diagram, we need to identify the minimum number of test cases required to cover every unique sequence of exactly 4 states/3 transitions starting and ending in the "Inactive" state.

The states are:

Inactive

Active

Alert Mode

Alarm bell rings

Inactive -> Active -> Inactive -> Active -> Inactive

Sequence: Press Button, Enter PIN, Press Button, Enter PIN

Inactive -> Active -> Alert Mode -> Inactive

Sequence: Press Button, Sensor Activated, Enter PIN

Inactive -> Active -> Alert Mode -> Alarm bell rings -> Inactive

Sequence: Press Button, Sensor Activated, Timeout expired, Press Button

Test Case Analysis:These sequences cover every unique combination of exactly 4 states and 3 transitions starting and ending in the "Inactive" state.

Dynamic testing requires the execution of the software to evaluate its behavior and performance. In contrast, static testing involves examining the software's code, design, and documentation without executing the software. This makes static testing applicable to non-executable work products such as requirement documents, design documents, and source code.

In the V-model project described in the question, the tester can identify the following based on the provided information:

Expected result (II):The requirements specification clearly states that the app should only ask for access permissions to the camera and photos stored on the device during and after installation. This expected behavior is defined by the requirements.

Actual result (III):The tester observes that the app also requests access to all contacts on the device, which deviates from the expected result. This actual observation can be recorded accurately.

Given these details, the tester can specify the expected result (II) and the actual result (III) in the defect report. However, without more information, the tester cannot determine the test environment (I), the test level (IV), or the root cause (V).

Risk registeris a test planning work product as it documents identified risks and their mitigation strategies.

Risk informationfalls under test monitoring and control work products as it involves ongoing evaluation and reporting of risks.

Test casesare part of test design work products as they are derived from test conditions and designed to execute the testing scenarios.

Test conditionsbelong to test analysis work products as they define the items or events of a system that are to be tested​​.
