Before we start Test Plan vs Test Strategy, we need to know about what are test plan and test strategy?.
Test plans and test strategies play a very important role in the process of testing a software application a good test plan and good strategies always refrain from bugs in an application.
As software testers, we should be aware of these two terms, which play a major role to test a software application. Here we will understand what is Test Plan and Test Strategies:
A Test Plan is known as a document that has all the beneficial information and is used to test the software application. A test plan is a deliverable that is defined by the test lead or testing team.
A test plan can consist of all QA-related activities like it defines the scope of the project, related roles and responsibilities, test objectives, entry and exit criteria of testing, and all the related risks which we are going to face while testing an application.
The Test plan will be based on the requirement gathered by a stockholder, which can be used by other testers or team members when due for some reason any of the team members are replaced by other testers so by using this document a tester should understand the requirement and can collect all related information that can be used to test a software application. Test plan can also include who will test what, suppose there is a module 1 which is going to be tested by “Tester A” but due to some reason “Tester A” is replaced by “Tester B” so by using a test plan “Tester B” can collect information and proceed to test application this can save time and have a better understanding about testing an application.
The basic purpose of test strategy is to define the testing process, it defines all related information about testing, like what tool we are going to use to test software application, and it defines the different modules which are undergoing while testing the application, it also defines the time needed to test module, a number of resources, what strategy we are going to use to test application, including information about high-level design, test planning, it also includes information about our test environment on which our application is going to be tested.
Below are some important sections a Test Strategy should have:
In the above diagram the test approach is differentiated into two sections:
Difference between Test Plan and Test Strategy:
|Test Plan||Test Strategies|
|The test plan can be derived from the Software requirement traceability matrix.||Test strategies can be derived from Business requirement specifications.|
|If there are any changes done in the requirement then the test plan should be updated.||Test strategies remain static while preparing documents, it’s static.|
|We can prepare a test plan based on the project.||Test strategies can be used multiple times in different projects.|
|The test plan defines what to test, how to test, and who will test.||It defines what type of tool and procedure we are going to follow to test software applications.|
|A test plan is written after gathering all information.||Test strategies are made before the test plan.|
|A test plan should be clear and concise.||Test strategies provide a guide to test applications.|
In Test Plan, all modules are defined with the corresponding tester and test cycle number have been mentioned who tested a module, therefore if some module fails in the particular cycle, we can easily check the corresponding cycle and check whether the specified module was passed or failed and if there is any failure, we can fix it.
Test strategy can’t be changed frequently as it has some standards test strategies will affect the quality of the testing, Good test planning and strategies lead to the quality of the product.
