testcriteria

Test criteria are the conditions that determine how testing is planned, executed, and evaluated. They establish when testing can start (entry criteria) and when it is complete (exit criteria), and they specify what constitutes a successful test outcome from a quality and risk perspective. Test criteria help ensure that testing covers the most important requirements and quality attributes and that decisions about progress and release are made consistently.

Entry criteria typically include the availability of a stable build, a test environment that matches production, complete test data, documented requirements, and sufficient testing personnel. They may also require approval from stakeholders and the availability of relevant tools and environments. Exit criteria describe conditions that must be met to close the test phase, such as a defined level of test execution (e.g., percentage of test cases run), acceptance of critical defects, meeting predefined test coverage, and the stability of the test environment for a given period.

Acceptance criteria specify user-visible behavior and performance that the system must demonstrate to satisfy stakeholders. Testability criteria focus on the system’s observability and controllability, including how easily testers can inspect internal states, reproduce issues, and automate tests. Tests are often categorized as functional or nonfunctional, and the criteria should address both categories.

In practice, test criteria influence test design, risk-based prioritization, and traceability to requirements. They provide a basis for objective go/no-go decisions and help align testing with regulatory, contractual, or quality standards when applicable.
