Software testing is a process of finding defects while the software is in the development phase so that they are not leaked to production and end-user. Both Test Plan and Test Strategy play an important role in the overall success of the testing process and the quality of the software delivery. Many stakeholders including project managers, developers, tech leads, and even software testers consider both are the same or similar. However, these two are considerably different and play a different role in the testing phase. Let's understand the difference between two -
Difference between Test Strategy and Test Plan
Importance of Test Strategy
Test strategy specifies the organizational strategy towards testing. It gives clear direction on organizational view on testing,
It gives a long team view on the organization's commitment towards quality delivery.
It provides a view into how the organization's strategy is approaching changes in technologies.
Importance of Test Plan
The creation of a test plan is a comprehensive process, but it is one that will prove to be beneficial in the entirety of the testing process.
A properly formulated test plan provides clarity to the testing process and each member's roles are clearly highlighted.
Test Plan is a defined rule book. Its existence guides the thought process of the team members and enlists the objectives and means to achieve that with a high degree of coherence.
Test Plan also reduces the disputes which may arise within the team without it.
Important aspects of the testing process like test estimation, test strategy, and scope are thoroughly documented and can be easily reviewed and re-used by the team.
Test Plan also provides a clearer picture to the client and members outside the testing team.
The main objective is to find as many defects as possible to make sure the software is bug-free.
Characteristics of a Good Test Strategy
An efficiently created test strategy should have the following characteristics:
A test strategy is just an approach and doesn't specify details about role and responsibilities,
It should articulate the strategy to handle all possible testing situations.
it is a generic document and should not be created with any project or business requirements in mind.
The test strategy doesn't change with the tactical changes in the testing approach.
