Comprehensive and Detailed In-Depth Explanation:Checklist-based testingusesspecific 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 incorrectbecause general guidelines lack specificity.

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

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

This answer is correct because Behavior-Driven Development (BDD) is a test-first approach, where tests that express a shared understanding from stakeholders of how the application is expected to work, are first written in business-readable language (following the Given/When/Then format), and then made executable to drive development. BDD is a collaborative approach that involves testers, developers, business analysts, product owners, and other stakeholders in defining the expected behavior of the application using scenarios that describe the preconditions, actions, and outcomes of the application. BDD scenarios are writtenusing a domain-specific language (DSL) that can be translated into executable test cases using tools such as Cucumber or SpecFlow. BDD aims to improve communication, collaboration, and feedback among the team members, and to deliver software that meets the customer’s needs and expectations. References: ISTQB Glossary of Testing Terms v4.0, ISTQB Foundation Level Syllabus v4.0, Section 3.1.1.4

Exploratory testing is an experience-based test technique in which testers dynamically design and execute tests based on their knowledge, intuition, and learning of the software system, without following predefined test scripts or test cases. Exploratory testing can be conducted following a session-based approach, which is a structured way of managing and measuring exploratory testing. In a session-based approach, the testers perform uninterrupted test sessions, usually lasting between 60 and 120 minutes, with a specific charter or goal, and document the issues detected, the test coverage achieved, and the time spent in session sheets. Session sheets are records of the test activities, results, and observations during a test session, which can be used for reporting, debriefing, and learning purposes. The other statements are false, because:

Exploratory testing is not a test technique in which testers explore the requirements specification to detect non testable requirements, but rather a test technique in which testers explore the software system to detect functional and non-functional defects, as well as to learn new information, risks, or opportunities. Non testable requirements are requirements that are ambiguous, incomplete, inconsistent, or not verifiable, which can affect the quality and effectiveness of the testing process. Non testable requirements can be detected by applying static testing techniques, such as reviews or inspections, to the requirements specification, before the software system is developed or tested.

Exploratory testing is not a test technique used by testers during informal code reviews to find defects by exploring the source code, but rather a test technique used by testers during dynamic testing to find defects by exploring the behavior and performance of the software system, without examining the source code. Informal code reviews are static testing techniques, in which the source code is analyzed by one or more reviewers, without following a formal process or using a checklist, to identify defects, violations, or improvements. Informal code reviews are usually performed by developers or peers, not by testers.

In exploratory testing, testers usually do not produce scripted tests and establish bidirectional traceability between these tests and the items of the test basis, but rather produce unscripted tests and adapt them based on the feedback and the findings of the testing process. Scripted tests are tests that are designed anddocumented in advance, with predefined inputs, outputs, and expected results, and are executed according to a test plan or a test procedure. Bidirectional traceability is the ability to trace both forward and backward the relationships between the items of the test basis, such as the requirements, the design, the risks, etc., and the test artifacts, such as the test cases, the test results, the defects, etc. Scripted tests and bidirectional traceability are usually associated with more formal and structured testing approaches, such as specification-based or structure-based test techniques, not with exploratory testing. References: ISTQB Certified Tester Foundation Level (CTFL) v4.0 sources and documents:

Boundary Value Analysis (BVA) is a software testing technique in which tests are designed to include values at the boundaries. The concept is to focus on the boundaries since errors tend to occur at the edges of input ranges rather than in the middle.

Given the problem statement:

Up to $100.00 = 2%

$100.01 to $500.00 = 4%

$500.01 to $1,000.00 = 5%

Above $1,000.00 = 7%

Two-point boundary value analysismeans testing the two boundaries of each range.

For each range:

The boundaries for "Up to $100.00" would be $100.00 and $100.01.

The boundaries for "$100.01 to $500.00" would be $100.00 and $500.00.

The boundaries for "$500.01 to $1,000.00" would be $500.00 and $1,000.00.

The boundaries for "Above $1,000.00" would be $1,000.00 and $1,000.01.

Now, let's examine the options:

A. $5.00, $100.00, $499.99, $1,000.00, $1,000.01

Missing $100.01 and $500.01.

B. $100.00, $100.01, $100.02, $500.00, $999.99

Covers $100.00, $100.01, $500.00, $1000.00, and $1000.01.

C. $100.00, $500.00, $1,000.00, $1,000.01

Missing $100.01 and $500.01.

D. $5.00, $100.00, $500.00, $1,000.01

Missing $100.01 and $500.01.
