Testtypes

Testtypes refers to the categories and classes of testing used in software development to verify that a product meets its requirements and behaves as intended. The term encompasses the objectives, scope, and techniques applied during testing and guides planning, execution, and evaluation of test activities.

Functional testing is concerned with validating that software functions perform according to specifications. This includes unit testing, which examines individual components or functions; integration testing, which checks interfaces between components; system testing, which verifies the complete and integrated product; and acceptance testing, which assesses whether the software meets user needs and is ready for release. Regression testing, performed after changes, ensures that existing functionality remains intact.

Non-functional testing evaluates aspects of system behavior that are not tied to specific functions. Common types include performance testing (response time and throughput), load testing (handling expected user loads), stress testing (breaking points), reliability testing (fault tolerance over time), usability testing (ease of use), security testing (vulnerabilities and protections), compatibility testing (works across platforms), and accessibility testing (conformance to accessibility standards). Other categories cover portability, maintainability, and compliance with regulatory or industry requirements.

Exploratory and ad hoc testing describe less formal, learning-driven approaches used to uncover defects without predefined test cases. Alpha and beta testing refer to internal and external validation before wide release. Smoke and sanity testing are quick checks to confirm basic stability after changes.

Planning for testtypes involves considering requirements, risk, and stage in the development lifecycle, selecting appropriate types, and often balancing manual and automated approaches. Results are tracked with metrics such as defect density, pass rates, and test coverage to inform quality decisions.
