In the Resolution phase of the Defect Lifecycle, the defect is assigned to a developer for resolution. This phase involves fixing the reported issues, and once resolved, the defect undergoes further verification to confirm that the fix is effective and the issue is truly resolved.

Continuous integration and continuous testing can provide faster feedback in an agile environment. These practices, along with automation testing, help improve test monitoring and control by ensuring that tests are executed regularly. Embracing a test-driven development approach and establishing clear communication channels are also important strategies to cope with frequent changes in requirements and enhance overall testing efficiency.

Cucumber is primarily used for Behavior-driven development (BDD), allowing collaboration between developers and non-developers to define and understand the behavior of a system. It facilitates automated testing based on these specifications, enhancing communication and ensuring alignment with business goals.

Security testing plays a crucial role in ensuring the robustness of a software application by validating its resistance to unauthorized access. This involves assessing vulnerabilities and implementing measures to safeguard the software from potential security threats and breaches.

The Page Object Model (POM) in Selenium provides advantages such as improved code reusability by encapsulating web elements, enhanced test maintenance through a clear separation of concerns, efficient parallel execution by creating modular and independent components, and simpler test script creation with a more readable and maintainable structure.

State Transition Testing is most suitable for ensuring that the traffic light control system changes state correctly. This technique validates transitions between different states in a system, making it ideal for scenarios where the system behavior depends on its current state.

A test case in functional testing is a set of instructions specifying the conditions, inputs, and expected results, guiding the tester through the execution of a particular test scenario.

In pairwise testing, each pair of parameters represents an interaction between input parameters. The approach aims to explore the potential interactions among different input values, focusing on uncovering defects that may arise from specific combinations. This targeted strategy helps identify issues efficiently, making it a valuable technique in reducing the number of test cases while maintaining coverage of critical interactions.

Even though the defect is low-severity, its impact on user experience is significant. Thus, it should be prioritized as high to address the importance of user satisfaction and overall product quality.

Collections in Postman allow testers to organize and execute test cases efficiently. A collection can group related requests, making it easier to manage and execute tests for a RESTful API. Testers can define workflows, dependencies, and run sequences, enhancing the organization and execution of test cases within the context of the social media platform API.
