testziel

Testziel is a term used in software testing and quality assurance to describe the intended outcome of a test. It specifies what is being tested, why the test is conducted, and the criteria by which the test is considered successful. A well-defined testziel helps align stakeholders, guides test design, and focuses measurement on relevant aspects of quality.

Typically, the testziel derives from requirements, user stories, or risk assessments. It translates into concrete acceptance criteria and informs the selection of test techniques, test data, and environments. By stating the objective early, teams can avoid scope creep and ensure that testing covers the most important risks.

Types of testziel can be functional or non-functional, including performance, reliability, security, usability, and compatibility objectives. A testziel should be specific and measurable, enabling objective evaluation of pass or fail outcomes for the test cases.

Example: The testziel for a login feature could be to verify that valid credentials are accepted within 2 seconds and that invalid credentials are rejected with a clear error message. Another example: verify that the checkout process completes within 5 seconds under load.

In project documentation, the testziel is typically stated in a test plan alongside scope, resources, and risk assessment. Common issues arise from vague or overly ambitious objectives that do not align with requirements or available data.
