Software application works as intended, by providing appropriate input and verifying the output against the functional requirements. It doesn’t delve into the source code of the application. Instead, it focuses on various aspects of the application, including API and User Interface.

It involves assessing vulnerabilities, measuring potential risks, and helping developers address security issues through coding. The six basic principles we follow for security testing are: Confidentiality, Integrity, Authentication, Authorization, Availability. So, security testing acts as a protective shield, safeguarding systems from unauthorized access, data breaches, and other security-related issues.

Performance testing is a non-functional testing technique that evaluates the speed, scalability, and stability of an application under a given workload. Its primary goal is to ensure the quality of the software and prepare the application for release into the market. It ensures your application meets user expectations and performs well in real-world scenarios.

A type of software testing performed to ensure that the application being tested is usable by people with disabilities. These disabilities may include- Vision Disability, Physical Disability, Cognitive Disability. Approximately 20% of the population faces disability-related issues. By making software disabled-friendly, companies can tap into this significant market. In summary, accessibility testing ensures that software products are inclusive, comply with legal requirements, and provide a positive user experience for everyone.

Compatibility testing is a type of testing that examines and compares functionality over multiple browsers, devices, platforms, and OS to recognize potential discrepancies. It ensures your software works correctly across various environments.

Usability testing refers to evaluating a product or service by testing it with representative users. Typically, during a test, participants will try to complete typical tasks while observers watch, listen, and takes notes.
