Difference between Test Strategy and Test Plan

A Test Strategy document is a high level document and normally developed by project manager. This document defines “Testing Approach” to achieve testing objectives. The Test Strategy is normally derived from the Business Requirement Specification document.

The Test Strategy document is a static document meaning that it is not updated too often. It sets the standards for testing processes and activities and other documents such as the Test Plan draws its contents from those standards set in the Test Strategy Document.

In this we define, what testing methods we use and what are the time lines.

Test Plan document on the other hand, is derived from the Product Description, Software Requirement Specification SRS, or Use Case Documents.

The Test Plan document is usually prepared by the Test Lead or Test Manager and the focus of the document is to describe what to test, how to test, when to test and who will do what test.

In this we define, what to Test, Scope ,Approach and What are the modules to test.

When a project gets initiated, we create the test strategy first. Test-Strategy will tell how to go about testing a business requirement or feature. It details the approach that you will implement to ensure that the product is ready for shipping by release date. This will include the high level functional and non functional test-scripts that you run based on the requirements.
Test plan is created at a later stage. Check the article below to get a details understanding on that:
