Quick and Structured Test Case Writing with GIVEN‑WHEN‑THEN and Exploratory Scenario Association

The article is aimed at junior software testers and anyone who wants to broaden testing scope and improve coverage.

It first describes the purpose of a test case—guiding testers through predefined conditions, steps, and expected results—and outlines the three core components: pre‑conditions, steps, and expected outcomes.

A simple, temporary template called GIVEN‑WHEN‑THEN is introduced: GIVEN states the pre‑condition, WHEN describes the action steps, and THEN defines the expected result. An example of testing a link to http://www.baidu.com demonstrates the template.

The article then presents the Exploratory Scenario Association method for deriving new test cases from existing ones. It explains how changing pre‑conditions (hardware or software resources), altering steps (inserting, deleting, modifying, or repeating steps), and leveraging test conclusions can generate additional scenarios.

Specific techniques include inserting related or unrelated steps, deleting key or non‑key steps, changing step order or content, and repeating steps to uncover faults under different conditions.

Finally, the article concludes that the GIVEN‑WHEN‑THEN template combined with exploratory scenario association provides a fast way to document test cases and expand test coverage, helping testers discover more defects across varied scenarios.
