Component integration testing is the process of testing the interactions between different components of a system. It should always be done before system testing, which is the process of testing the system as a whole. Integration testing can reveal defects in the interfaces and interactions between components, which can affect the functionality and performance of the system. System testing can reveal defects in the system requirements, design, and behavior, which can affect the quality and usability of the system. Therefore, it is logical to perform integration testing before system testing, to ensure that the components work together correctly before testing the system as a whole.

The correct logical order for the test cases is 3, 1, 4, 2, 6, 5. This order follows the logical sequence of actions that a user would perform to book a flight using a web-based airline booking system. The order also respects the dependencies between test cases, such as logging in before searching for flights or booking a flight before printing a confirmation receipt . The other options are incorrect logical orders for the test cases. Option A does not follow the logical sequence of actions and does not respect the dependencies between test cases. For example, it starts with confirming details and booking a flight before logging in or selecting a flight. Option B does not follow the logical sequence of actions and does not respect the dependencies between test cases. For example, it starts with selecting a flight before logging in or searching for flights. Option C does not follow the logical sequence of actions and does not respect the dependencies between test cases. For example, it starts with viewing selected items in My Flights before selecting any flights.

Testing and debugging are two different activities that are related to finding and removing defects and failures in software. Testing is the process of evaluating software by applying test cases to find failures and provide information on its quality. Debugging is the process of finding, analyzing, and removing the causes of failures in software. Testing reveals failures, which are deviations of the actual behavior of the software from its expected behavior. Debugging removes defects, which are flaws in the software that cause failures.

Having the company's independent test team design and execute the tests would achieve the highest level of testing independence for a project's test level, because it would reduce the bias and influence of the developers or other stakeholders who are involved in the software development1.An independent test team can provide a different perspective and focus on testing activities without being affected by development pressures or deadlines1. The other options would not achieve the highest level of testing independence for a project's test level.Option A is not a good option, because training developers to design good tests for the test team to execute would still introduce some bias and influence from the developers' point of view1.Option C is not a good option, because minimizing contact between testers and developers during test design to avoid bias would reduce the communication and collaboration that are essential for effective testing and defect resolution1.Option D is not a good option, because outsourcing test design and execution to a different company would introduce some risks and challenges such as contractual issues, cultural differences, or loss of control over quality

A key difference between black box and white box test design techniques is that white box techniques can measure the extent of code coverage, while black box techniques cannot. Code coverage is a measure of how much of the code of a system or component has been executed by a test or a set of tests. White box techniques use software code to derive test cases that cover specific aspects of the code, such as statements, branches, paths, or data flows. White box techniques can use tools or methods to measure the code coverage achieved by the test cases and identify any gaps or redundancies. Black box techniques use functional design specifications to derive test cases that cover specific aspects of the functionality, behavior, or quality of the system or component, such as inputs, outputs, equivalence classes, boundary values, states, transitions, etc. Black box techniques do not use or access the code of the system or component, and therefore cannot measure the code coverage.
