A correct list of boundary values for the P input should include the minimum and maximum values of the valid range (15 and 350), as well as the values just below and above the boundaries (14 and 351). Boundary value analysis is a test design technique that involves testing the values at or near the boundaries of an input domain or output range, as these values are more likely to cause errors than values in the middle. Option B satisfies this condition, as it has all four boundary values (14, 15, 350, 351). Option A has only two boundary values (14 and 351), option C has only two boundary values (15 and 350), and option D has no boundary values at all.

Experience-based test techniques are test design techniques that rely on the experience, knowledge, intuition, and creativity of the testers to identify and execute test cases that are likely to find defects in the software system. Experience-based test techniques are often useful to detect hidden defects that have not been targeted by black-box test techniques, which are test design techniques that use the external behavior and specifications of the software system as the test basis, without considering its internal structure or implementation. Experience-based test techniques can complement black-box test techniques by covering aspects that are not explicitly specified, such as usability, security, reliability, performance, etc. The other statements are false, because:

Experience-based test techniques do not rely on the experience of testers to identify the root causes of defects found by black-box test techniques, but rather to identify the potential sources of defects based on their own insights, heuristics, or exploratory testing. The root causes of defects are usually identified by debugging or root cause analysis, which are activities that involve examining the code or the development process to find and fix the errors that led to the defects.

Some of the most common test basis used by white-box test techniques include the source code, the design documents, the architecture diagrams, and the control flow graphs of the software system. White-box test techniques are test design techniques that use the internal structure and implementation of the software system as the test basis, and aim to achieve a certain level of test coverage based on the code elements, such as statements, branches, paths, etc. User stories, use cases, and business processes are examples of test basis used by black-box test techniques, as they describe the functional and non-functional requirements of the software system from the perspective of the users or the stakeholders.

The primary goal of experience-based test techniques is not to design test cases that can be easily automated using a GUI-based test automation tool, but rather to design test cases that can reveal defects that are not easily detected by other test techniques, such as boundary value analysis, equivalence partitioning, state transition testing, etc. Test automation is the use of software tools to execute test cases and compare actual results with expected results, without human intervention. Test automation can be applied to different types of test techniques, depending on the test objectives, the test levels, the test tools, and the test resources. However, test automation is not always feasible or beneficial, especially for test cases that require human judgment, creativity, or exploration, such as those designed by experience-based test techniques.Reference: ISTQB Certified Tester Foundation Level (CTFL) v4.0 sources and documents:

White-box test techniques are test design techniques where the test cases are derived from the internal structure of the software, including its architecture, code, and logical flow. These techniques involve the tester having knowledge of the internal workings of the software to create test cases that ensure all possible paths and conditions are tested. This is in contrast to black-box test techniques, which focus on input-output behavior without considering the internal structure. Reference: ISTQB CTFL Syllabus V4.0, Section 4.3

Static testing involves reviewing and inspecting the code, requirements, or design documents without executing the code. It can prevent defects, is effective early in the software development life cycle, and can help eliminate defects in user stories.

Option 1: 'It can prevent defects by manual examination of the functional specification' - This is a value of static testing.

Option 2: 'It is effective since it can be performed very early in the software development life cycle' - This is a value of static testing.

Option 3: 'It can detect the failures in the running application' - This is a v (ISTQB not-for-profit association)namic testing, not static testing.

Option 4: 'It can help eliminate defects in user stories' - This is a value of static testing.

Option 5: 'It can verify externally visible behaviors' - This is a value of dynamic testing, not static testing.

Therefore, the correct set of statements representing values only for static testing is 1, 2, 4, which corresponds to answer C6source.

Comprehensive and Detailed In-Depth Explanation:

The correct tool for creating test cases, test data, and test procedures is a test design and implementation tool (A).

(B) is incorrect as static testing tools focus on code analysis, not test case creation.

(C) is incorrect because DevOps tools manage automation pipelines, not test design.

(D) is incorrect because test execution tools focus on running tests rather than designing them.

Test design tools help optimize test coverage, reduce redundancy, and improve efficiency.
