Unit Testing is the type of testing performed to verify that individual units or components of a software system work correctly. It focuses on isolated testing of these units to identify and address defects at an early stage.

In Agile deployment, new features are incrementally rolled out to the user base, allowing for continuous feedback and adjustments throughout the development process.

The Testing Phase in the SDLC is dedicated to verifying that the software meets specified requirements and is free of bugs. This phase ensures the software's quality and functionality.

Adhering to the KISS principle simplifies code, making it easier to understand and maintain. Complex code can lead to difficulties in maintaining and debugging.

Not adhering to design principles like SOLID in a large-scale project can lead to reduced code readability and maintainability. This can result in increased technical debt, making it challenging to modify, expand, or maintain the software in the long term. SOLID principles promote code quality and long-term maintainability.

JUnit is a widely used testing framework for unit testing in Java applications. It provides annotations, assertions, and test runners to facilitate the testing of Java code, making it a popular choice for developers.

The Canary deployment strategy involves testing a new release on a small subset of the production environment before full deployment. It helps identify potential issues or bugs, reducing the risk to the entire system.

Strict adherence to coding style can help in identifying syntax errors and deviations from coding standards during development. Consistent style and formatting make the code more readable and maintainable.

Manual review is a code review technique where the reviewer independently examines the code, identifying potential issues and providing feedback.

When designing for ease of use and accessibility, prioritizing minimalism and consistency in user interface design is crucial. This approach simplifies the user experience and ensures content is accessible to a wide range of users.

A Software Requirements Specification is a formal document that outlines the detailed requirements and specifications of a software system. It serves as a critical reference for developers and other stakeholders to understand what the software should achieve. It's an essential artifact in the SDLC.

System testing verifies that the entire system, including all integrated components, functions according to specified requirements and works as a whole.
