Testing Terms Glossary
The set of conditions that a user, customer, or any authorized entity requires a component or system to meet before it can be considered approved or accepted.
The procedure in which users test a software or system and decide to either approve or reject its acceptance based on the outcomes. It involves evaluating the program against its initial requirements and the current needs of its end users. This type of test is atypical because it is typically carried out by the software’s customer or end user rather than the development organization. Its purpose is to assess the system’s readiness for implementation or use. It is a formal testing process to determine whether the system meets its acceptance criteria and allows the customer to decide whether to accept or reject it.
Ensuring that a product is usable and available to individuals with disabilities.
The ability of the software product to deliver the intended or agreed-upon outcomes or effects with the required level of accuracy.
The act of spontaneously and ad hoc searching for software bugs. This type of testing is conducted without formal preparation, without following established test design techniques, and without any specific expectations for results. The test execution activity is guided by randomness or arbitrary choices.
Agile Testing integrates testing throughout development, emphasizing continuous feedback and collaboration. It employs test-driven development, automation and adapts to changing requirements. The approach catches defects early, maintains code quality, and improves efficiency. Agile Testing delivers high-quality software through rapid iterations and effective communication.

Alpha testing is an internal testing process carried out by the manufacturer to verify the functionality and capabilities of a new product. It involves following a set of testing procedures to assess the product’s performance. This testing phase occurs before beta testing and is conducted by the manufacturer’s test team, along with potentially other interested individuals within the company.
An anomaly refers to any situation that deviates from the expected outcome as defined by requirements specifications, design documents, user documents, standards, or personal perception and experience.

Anomalies encompass any discrepancies or deviations encountered throughout these processes, signaling deviations from the norm or expected behavior.
