Software Testing Fundamentals

HTML comments in production code can reveal implementation details, debugging information, database structure, or security vulnerabilities to attackers. This is not secure coding practice. Comments should be removed or minimized before deployment.

The Test Analysis and Design phase includes creating test cases, designing test environment set-ups, and identifying required infrastructure and tools. This comes after test planning but before actual test implementation and execution. Test Implementation involves running tests, Evaluating Exit Criteria happens after execution, and Test Closure is the final phase.

According to standard testing methodologies, tasks i, ii, and iii belong to test implementation and execution. Establishing or determining exit criteria (task iv) is a planning activity. Therefore, i, ii, and iii are true and iv is false.

The valid range is 18-25 inclusive. An invalid equivalence class includes values outside this range. Option A (17) is below the valid range, making it invalid. Options B, C, D are all within the valid range (19, 24, 21).

To clear the exam, a student must score between 24 and 40 marks inclusive. Valid equivalence values must all fall within this passing range. Option C (29, 30, 31) has all values in the valid range 24-40. Options A and B include values below 24, while Option D has only invalid values.

To solve this question, the user needs to be familiar with software testing and the different types of testing that are performed in software development.

The question is asking for the name of the type of testing that is also known as Link Testing. Link Testing is a type of testing that is used to verify the proper integration of different software components.

Now, let's go through each option and explain why it is right or wrong:

A. Component Integration testing: This option is correct. Component Integration testing is another name for Link Testing. This type of testing is used to verify the proper integration of different software components.

B. Component System Testing: This option is incorrect. Component System Testing is a type of testing that focuses on testing individual components of the system.

C. Component Sub System Testing: This option is incorrect. Component Sub System Testing is not a commonly used term in software testing.

D. Maintenance testing: This option is incorrect. Maintenance testing is a type of testing that is performed to verify that changes made to the software have not introduced new defects.

Therefore, the answer is: A. Component Integration testing.

The cost of fixing a fault increases exponentially as the software development lifecycle progresses. A defect found in requirements is cheapest to fix, while one found in production is most expensive due to rework, testing, and deployment costs. This is a fundamental principle of software economics.

Verification answers 'Are we building the product right?' - checking the quality of the built product against specifications. Validation answers 'Are we building the right product?' - checking user needs. Option B correctly identifies that verification focuses on quality of the built product, while the other statements describe different activities or are incorrect.

Reviews and inspections are static testing techniques that examine documents and code without executing them. Like dynamic testing, they aim to detect defects and improve quality. Option D correctly recognizes that both activities serve the same fundamental purpose - finding faults early.

Performance testing measures system responsiveness, throughput, and stability under load. It includes response time (A), transaction rates (B), and simulating many users (D). Recovery testing (C) checks system ability to recover from failures, which is a different non-functional testing type.

The question asks which statement about static testing is FALSE. Static testing does NOT require running tests through code - that's dynamic testing. Option A correctly states this false claim. Static testing includes reviews (C), desk checking (B), and can measure metrics like cyclomatic complexity (D) without code execution.

To solve this question, the user needs to know about Equivalence classes which are used in software testing to divide a set of test cases into groups or sets that can be run together. Each set of test cases represents a particular behavior or functionality of the system under test.

In this question, the text box on the form accepts numeric values in the range of 18 to 25. Therefore, the valid equivalence classes will be the range of values between 18 to 25, including 18 and 25. Any value outside of this range will be an invalid equivalence class.

Now, let's go through each option and identify the invalid equivalence class:

A. 17: This option is not a valid equivalence class because it falls outside of the valid range of values between 18 to 25.

B. 19: This option is a valid equivalence class because it falls within the valid range of values between 18 to 25.

C. 24: This option is a valid equivalence class because it falls within the valid range of values between 18 to 25.

D. 21: This option is a valid equivalence class because it falls within the valid range of values between 18 to 25.

Therefore, the invalid equivalence class is:

A. 17

The answer is: A.

A student clears the exam by scoring between 24 and 40 marks inclusive. The valid equivalence class for passing consists of values in this range. The set [29, 30, 31] contains only valid passing marks. Other sets include failing marks below 24.

Performance testing measures system responsiveness, throughput, and stability under load. It includes response time (A), transaction rates (B), and simulating many users (D). Recovery testing (C) checks system ability to recover from failures, which is a different non-functional testing type.

Verification ensures that the product conforms to its specifications, which helps check the quality of the built product (statement i). Checking if we built the right product (statement ii) is validation. Developing the product (iii) and monitoring tool wastage (iv) are not verification tasks.
