ISTQB-CTFL Exam Dumps - ISTQB Foundation Level Questions and Answers

Non-functional testing refers to testing aspects that do not relate to specific behaviors or functions of the software but to attributes such as performance, usability, reliability, etc. Tests that capture the time it takes to save a file directly relate to the performance of the system, thus falling under non-functional testing.

Comprehensive and Detailed In-Depth Explanation:

The ratio-based estimation method relies on historical relationships between development and testing effort.

Using the given 5:3 ratio:

Thus, the correct answer is 270 person-days (D).

(A) and (C) are incorrect as they overestimate the effort.

(B) underestimates the testing effort based on the ratio.

Ratio-based estimation helps allocate resources effectively based on past project data.

To achieve 100% branch coverage of the process flow, we need to test both the true and false outcomes of the condition (User presses Cancel). Branch coverage is a type of structural testing that measures how many decision outcomes in a program have been executed by a test suite. Branch coverage can be used to assess the adequacy or completeness of a test suite.

To test the true outcome of the condition, we need a test case that simulates the user pressing Cancel after booking a bill. This test case will exit the loop and end the process flow.

To test the false outcome of the condition, we need a test case that simulates the user not pressing Cancel after booking a bill. This test case will repeat the loop and book another bill.

Therefore, we need at least two test cases to achieve 100% branch coverage of the process flow. One test case for each possible outcome of the condition.

Comprehensive and Detailed In-Depth Explanation:

Checklist-based testing uses specific test conditions (B) that help testers ensure key aspects are validated. The checklist items can be derived from past defects, requirements, or regulatory standards.

(A) is incorrect because general guidelines lack specificity.

(C) is incorrect because checklists can be used for both manual and automated testing.

(D) is incorrect because checklists are useful for both functional and non-functional testing (e.g., security, performance).

Checklists help ensure completeness without enforcing strictly scripted execution.

An incident report is a document that records the details of an incident. An incident report typically contains the following items:

Identifier: A unique identifier for the incident report

Summary: A concise summary of the incident

Description: A detailed description of the incident, including the steps to reproduce it, the expected and actual results, and any relevant screenshots or logs

Severity: The degree of impact that the incident has on the system

Priority: The level of urgency for resolving the incident

Status: The current state of the incident, such as new, open, resolved, closed, etc.

Resolution: The action taken to resolve the incident, such as fix, workaround, reject, etc. Based on the information given in the question, the tester would be able to write down all of these items except for the test case identifier. A test case identifier is a unique identifier for a test case that is used to link it to other test artifacts, such as test plans, test scripts, test results or incident reports. However, since the tester is performing exploratory testing, there is no predefined test case that can be associated with the incident. Exploratory testing is an approach to testing that emphasizes learning, test design and test execution at the same time. Exploratory testing relies on the tester’s skills, creativity and intuition to explore the software under test and discover defects. Exploratory testing does not use formal test cases or scripts, but rather uses test charters or missions that guide the tester’s actions and objectives.

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】.

In the context of software testing, the ISTQB Certified Tester Foundation Level (CTFL) v4.0 differentiates between "validation" and "verification" based on their respective focuses in the software development lifecycle. Verification is the process of evaluating a system or component to determine whether the products of a given development phase satisfy the conditions imposed at the start of that phase. In simpler terms, verification is about checking the product against the specified requirements to ensure it was built correctly. Validation, on the other hand, involves evaluating a system or component during or at the end of the development process to determine whether it meets specified requirements for its intended use. This means validation is about ensuring the product fulfills its intended use and meets the needs of the user.
