To answer this question, we need to understand what white box testing techniques are.

White box testing is a software testing technique that involves testing the internal structure, design, and implementation of a software application. It requires knowledge of the internal workings of the system, such as the code, logic paths, and data flow.

Let's go through each option to determine which one is not a white box technique:

Option A) Statement Testing and coverage - This option is a white box technique. It involves testing each statement in the code and ensuring that all statements are executed at least once.

Option B) Decision Testing and coverage - This option is also a white box technique. It focuses on testing the various decision points in the code, such as if-else statements and switch statements, and ensuring that both true and false conditions are tested.

Option C) Condition Coverage - This option is also a white box technique. It involves testing all possible conditions within a decision point, such as testing each condition within an if-else statement.

Option D) Boundary value analysis - This option is not a white box technique. Boundary value analysis is a black box testing technique that focuses on testing the boundaries or extremes of input values. It does not require knowledge of the internal structure or implementation of the software.

Therefore, the correct answer is D) Boundary value analysis. This option is not a white box technique because it falls under the category of black box testing techniques.

To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A) Requirements - Incidents can be raised against requirements if there are issues or errors in the specified requirements. Therefore, this option is incorrect.

Option B) Documentation - Incidents can be raised against documentation if there are mistakes or inconsistencies in the provided documentation. Therefore, this option is incorrect.

Option C) Test Cases - Incidents can be raised against test cases if there are defects or failures identified during the testing process. Therefore, this option is incorrect.

Option D) Improvements suggested by users - Incidents are typically not raised against improvements suggested by users. These suggestions are usually considered as enhancements rather than issues or defects. Therefore, this option is correct.

The correct answer is D) Improvements suggested by users. This option is correct because incidents would not be raised against improvements suggested by users.

To answer this question, you need to understand the different levels of testing and their purposes. Let's go through each option to understand why it is correct or incorrect:

Option A) System Level Testing - This option is incorrect. System level testing is performed to validate the entire system against the specified requirements, not specifically to expose defects in interfaces or interactions between integrated components.

Option B) Integration Level Testing - This option is correct. Integration level testing is performed to test the interaction and interfaces between integrated components. It aims to expose defects that may arise due to the integration of these components.

Option C) Unit Level Testing - This option is incorrect. Unit level testing is performed to test individual units or components of software. It focuses on verifying the functionality of each unit in isolation, rather than testing the interaction between integrated components.

Option D) Component Testing - This option is incorrect. Component testing is another term for unit level testing. It refers to testing individual components or units of software. It does not specifically focus on testing the interaction between integrated components.

The correct answer is B) Integration Level Testing. This option is correct because it specifically refers to testing the interfaces and interaction between integrated components to expose defects.
