Test Plan VS. Test Strategy
In this section, we are going to discuss the major difference between the Test Plan and Test Strategies as we already know that both are an important part of Testing documentation.
As test engineers, we must be aware of these two testing terms as they play a major role in the Software Test Life Cycle (STLC). And for the interview purpose, it is the most commonly asked question.
But before we get into the difference between Test Plan and Test Strategy first, we will understand the concepts of Test Plan and Test Strategy in brief.
What is Test Plan?
The test plan is a base of software testing. It is a detailed document, which includes several testing attributes such as test objectives, scope, test schedule, template, required resources (human resources, software, and hardware), test estimation and test deliverables, risk, mitigation plan, defect tracking, entry and exit criteria, test environment, etc., which defines software testing areas and activities.
The test plans play a major role in testing and help us deliver a quality product.
What is a Test Strategy?
The test strategy is a high-level document used to validate the test levels to be executed for the product. And it also describes what kind of technique has to be used and which module will be tested.
It contains various components like documentation formats, objectives, test processes, scope, customer communication strategy, etc.
The Test Strategy's main purpose is to deliver a systematic approach to the software testing process to ensure reliability, quality, traceability, and better planning.
Difference between Test Plan and Test Strategy
In the below table, we have listed some of the important difference between Test Plan and Test Strategy:
Fundamentally, in a Test plan, all the names of the test engineers and test cycle numbers have been mentioned who tested a particular script. Therefore, if some feature fails in the particular cycle, we can easily refer to the previous cycle to check if that specified module was passed or failed.
Test strategy can't frequently change as it sets some standards for the test plan. And it becomes difficult to stick to a precise plan and modified strategy because if the requirement changes happen repeatedly, it will affect the quality of the testing, and we may not be able to deliver a quality product.
