Cyclomatic Complexity is a metric used in white-box testing that determines the complexity of a program. It calculates the number of linearly independent paths through a program's source code by assessing the number of executed edges over total edges.

"Interrupt Testing" focuses on ensuring that the mobile application can handle interruptions gracefully, such as incoming calls, low battery warnings, or intermittent loss of network connectivity, without malfunctioning or crashing.

The "Test Level Definition" in a test strategy outlines which level of testing should be applied, whether it's unit, integration, system, or any other level. This helps in ensuring that the right testing techniques are used at the appropriate stages of development.

A Compliance Audit is a detailed review process that ensures an organization is adhering to the regulatory guidelines applicable to them. This could be in the context of financial, operational, or IT-related regulations. Such audits provide assurance that the organization operates within legal confines.

Continuous Integration relies on developers frequently integrating their changes into a main or shared branch, allowing for quick detection of integration issues. This frequent merging ensures that issues are detected and fixed early, reducing the integration pains at later stages.

Automated tests are most effective when they don't require frequent modifications. Test cases that need constant updates due to changing requirements can be resource-intensive to maintain in an automated framework, thus reducing the efficiency benefits of automation.

Usability Testing focuses on evaluating a product's user interface (UI) and overall user experience (UX). The main aim is to ensure that the app is user-friendly, intuitive, and efficient. It assesses how easily users can perform tasks and navigate through the application without facing hurdles.

"ARIA Landmarks" are used to enhance the accessibility of web content. ARIA stands for "Accessible Rich Internet Applications". These landmarks help screen readers understand the purpose of different areas of a webpage, making navigation and interaction easier.

Control flow, data flow, and path coverage are core types of static analysis techniques. Path coverage ensures that every potential route through a given part of the code is executed, thereby identifying areas that have not been tested.

SonarQube is a popular tool used for static code analysis. It scans source code for vulnerabilities, bugs, and code smells, providing a comprehensive overview of code quality. JIRA, Selenium, and Jenkins serve different purposes in the software development lifecycle.
