testaustyyppejä

Testaustyyppejä, or testing types, refers to the various categories and approaches used in software development and other fields to verify the quality and correctness of a product or system. These types are often distinguished by their objectives, the scope of what is being tested, and the methods employed.

Functional testing examines whether a system's features and functionalities operate as specified by the requirements. This includes various sub-types like unit testing, where individual components are tested in isolation, integration testing, which verifies the interaction between different modules, and system testing, which evaluates the complete integrated system. Acceptance testing, performed by end-users or clients, ensures the system meets business needs and user expectations.

Non-functional testing focuses on aspects beyond specific functions, such as performance, usability, security, and reliability. Performance testing, for example, assesses the system's responsiveness, stability, and resource utilization under various loads. Security testing aims to identify vulnerabilities and protect the system from unauthorized access or attacks. Usability testing evaluates how easy and intuitive the system is for users to operate.

Other common testing types include regression testing, which ensures that recent changes have not negatively impacted existing functionalities, and smoke testing, a preliminary check to ensure a new build is stable enough for further testing. Exploratory testing involves simultaneous learning, test design, and execution, allowing testers to discover defects in a more flexible manner. The selection of appropriate testing types depends on the project's requirements, risks, and resources.
