What Is Test Plan?

While a test strategy is high-level and long-lived, a test plan is specific and time-bound. A typical test plan includes the scope (what is being tested and explicitly what is not), the test approach (manual vs. automated, by feature area), entry criteria (when testing can begin), exit criteria (when testing is considered complete), test environment requirements, test data needs, risk assessment with contingency plans, resource allocation and schedule, and deliverables (reports, defect summaries).

The IEEE 829 standard provides a formal template, but most agile teams use lighter versions. The key is that the plan is a living communication tool, not bureaucratic documentation. It should be concise enough that the team actually reads it and specific enough to guide day-to-day testing decisions.

Common pitfalls include writing plans that are too vague ("we will test everything"), too ambitious (planning coverage that resources cannot support), or never updated after initial creation. Effective test plans are reviewed with developers and product owners and revised as scope changes during the sprint.
