ISTQB-CTFL Exam Dumps - ISTQB Certified Tester Foundation Level (CTFL v4.0)

To achieve 100% statement coverage, we need to design test cases that ensure every statement in the given pseudo-code is executed at least once. Analyzing the pseudo-code, we notice that there are conditions based on two variables: Gender and Age. To cover all statements, we need to consider the paths that lead to each assignment of the Shoe Size variable.

Gender = Boy, Age <= 3 (Shoe Size assignment is not reached, but the condition is evaluated)

Gender = Boy, Age > 3 AND Age < 5 (Shoe Size = 1)

Gender = Boy, Age >= 5 AND Age < 7 (Shoe Size = 2)

Gender != Boy, Age <= 3 (Again, Shoe Size assignment is not reached, but the condition is evaluated)

Gender != Boy, Age > 3 AND Age < 5 (Shoe Size = 0)

Gender != Boy, Age >= 5 AND Age < 7 (Shoe Size = 1)

However, upon closer inspection, we see that tests 1 and 4 do not contribute to statement coverage as they do not lead to a Shoe Size assignment. Therefore, we only need 4 test cases to achieve 100% statement coverage, making option B the correct answer.

Static analysis is a technique that analyzes the source code or other software artifacts without executing them. Static analysis can detect defects such as syntax errors, coding standards violations, potential security vulnerabilities, or logical flaws. Static analysis can catch the bug in the first implementation, as it contains two syntax errors: the variable y is declared twice, and the assignment statement X = y=z is invalid. Static analysis cannot catch the bugs in the other three implementations, as they are logical errors that do not violate any syntax rules, but produce incorrect results.

The state transition diagram provided shows three distinct states:

Waiting for fingerprint

Waiting for PIN

Valid PIN/ask menu selection

Each state represents a different stage in the system's operation, with transitions based on user actions and system responses​​.

This answer is correct because error guessing is a test design technique where the experience and intuition of the tester are used to anticipate where errors, defects and failures have occurred or are likely to occur, and to design test cases to expose them. Error guessing can be based on factors such as the complexity of the system or component, the known or suspected weaknesses of the system or component, the previous history of defects, or the common types of errors in the domain or technology. Error guessing can be used as a complementary technique to other more systematic or formal techniques, or when there is insufficient information or time to apply them. References: ISTQB Glossary of Testing Terms v4.0, ISTQB Foundation Level Syllabus v4.0, Section 2.3.2.5

To apply one-dimensional equivalence partitioning to the ID requirement, we need to consider each condition individually:

Length of the ID: Valid partitions (5-10 characters), Invalid partitions (less than 5, more than 10) = 3 partitions.

Type of characters: Valid partitions (alphanumeric), Invalid partitions (non-alphanumeric) = 2 partitions.

First character: Valid partitions (letter), Invalid partitions (non-letter) = 2 partitions. Adding these partitions, we get a total of 3 (length) + 2 (character type) + 2 (first character) = 7 partitions. Thus, the correct answer is A​​.

Comprehensive and Detailed In-Depth Explanation:

During iteration planning, testers provide input on risk analysis, testability, and the feasibility of test automation. Participating in risk analysis (B) helps identify areas needing more extensive testing.

(A) is incorrect because the test strategy is usually set at a higher level (project or release level).

(C) is incorrect as release planning is broader than iteration planning.

(D) is incorrect since writing user stories is mainly the responsibility of the product owner, though testers contribute to defining acceptance criteria.

Risk-based test prioritization ensures testing efforts are aligned with business needs and software risks.

During the review planning stage, key decisions are made, including the selection of standards and procedures to be followed during the review. This planning phase ensures that the review process is structured and adheres to agreed-upon standards, which can come from industry standards such as ISO/IEC/IEEE 29119-3. The ISTQB CTFL Syllabus v4.0 emphasizes the importance of review planning in establishing the framework and guidelines for the review process​​.

When developers are trying to identify and remove a defect, they need clear information on what went wrong and what was expected. The items that will be most useful to developers in this context are the expected results (item 1), the actual results (item 2), and a description of the defect including steps to reproduce, screenshots, and database dumps (item 5). This information helps developers understand the nature of the defect and provides the necessary details to reproduce and diagnose the issue effectively.
