📅Test Strategy
A Test Strategy is a plan for defining an approach to the Software Testing Life Cycle (STLC). It guides QA teams to define Test Coverage and testing scope.
It helps Test managers to get the clear state of the project at any point. The chances of missing any test activity are very low when there is a proper test strategy in place.
Test execution without any plan rarely works. I know teams who write strategy document but never refer back while test execution. The Testing Strategy plan must be discussed with the whole team so that the team will be consistent with its approach and responsibilities.
In tight deadlines, you can’t just waive any testing activity due to time pressure. It must at-least go through a formal process before doing so.
In simple terms, test strategy contains the following information:
How to use testing for managing project and product risks?
How to divide testing process into different test levels?
What are the high level testing activities?
Which testing strategy should be used in which situation? Strategies can differ based on project requirements like regulatory requirements, risk levels and different methodologies of software development.
General test entry and test exit conditions
The activities and processes mentioned in the Test Strategy should be align with the organizations Test Policy.
Test strategy VS Test Plan
There is great confusion about Test Plan and Test Strategy documents. A different organization has their unique processes and standards to manage these documents. For example, some organization include test strategy facts in Test Plan itself while some organization includes strategy as a subsection within the testing plan.

How to prepare a good test strategy document
Every organization has their unique priority and set of rules for software designing, so do not copy any organization blindly. Always ensure that their document is compatible and adds value to your software development before following the template.
Step #1: Scope And Overview
Project overview along with information on who should use this document. Also, include details like who will review and approve this document. Define testing activities and phases to be carried out with timelines with respect to overall project timelines defined in the test plan.
Step #2: Test Approach
Define the testing process, level of testing, roles, and responsibilities of every team member.
For every test type defined in the Test plan (For Example, Unit, Integration, System, Regression, Installation/Uninstall, Usability, Load, Performance, and Security testing) describe why it should be conducted along with details like when to start, test owner, responsibilities, testing approach and details of automation strategy and tool if applicable.
In test execution, there are various activities like adding new defects, defect triage, defect assignments, re-testing, regression testing and finally test sign-off. You must define the exact steps to be followed for each activity. You can follow the same process that worked for you in your previous test cycles.
A Vision presentation of all these activities including a number of testers and who will work on what activities would be very helpful to quickly understand the roles and responsibilities of the team.
For example, defect management cycle – mention the process to log the new defect. Where to log in, how to log new defects, what should be the defect status, who should do defect triage, whom to assign defects after triage etc.
Also, define the change management process. This includes defining change request submissions, templates to be used, and processes to handle the request.
Step #3: Test Environment
The test environment setup should outline information about the number of environments and the required setup for each environment. For example, one test environment for the functional test team and another for the UAT team.
Define the number of users supported in each environment, access roles for each user, software and hardware requirements like operating system, memory, free disk space, number of systems, etc.
Defining test data requirements is equally important. Provide clear instructions on how to create test data (either generate data or use production data by masking fields for privacy).
Define test data backup and restore strategy. The test environment database may run into problems due to unhandled conditions in the code. I remember the problems we faced on one of the projects when there was no database backup strategy defined and we lost all the data due to code issues.
Backup and restore process should define who will take backups when to take a backup, what to include in backup when to restore the database, who will restore it and the data masking steps to be followed if the database is restored.
Step #4: Testing Tools
Define test management and automation tools required for test execution. For performance, load and security testing, describe the test approach and tools required. Mention whether it is an open source or commercial tool and how many users are supported on it and plan accordingly.
Step #5: Release Control
As mentioned in our UAT article, unplanned release cycles can result in different software versions in test and UAT environments. The release management plan with proper version history will ensure test execution of all modifications in that release.
For example, set build management process which will answer – where new build should be made available, where it should be deployed, when to get the new build, from where to get the production build, who will give the go, the no-go signal for production release, etc.
Step #6: Risk Analysis
List all the risks that you envision. Provide a clear plan to mitigate these risks along with a contingency plan in case you see these risks in reality.
Step #7: Review And Approvals
When all these activities are defined in the test strategy plan, they need to be reviewed for sign-off by all entities involved in project management, business team, development team, and system administration (or environment management) team.
A summary of the review changes should be tracked at the beginning of the document along with the approver's name, date and comment. Also, it’s a living document meaning this should be continuously reviewed and updated with testing process enhancements.
Simple Tips to Write a Test Strategy Document
Include product background in the test strategy document. Answer the first paragraph of your test strategy document – Why do stakeholders want to develop this project? This will help us understand and prioritize things quickly.
List all the important features you are going to test. If you think some features are not a part of this release then mention those features under “Features not to be tested” label.
Write down a test approach for your project. Clearly, mention what type of testing you are going to conduct? i.e., Functional testing, UI testing, Integration testing, Load/Stress testing, Security testing, etc.
Answer questions like how you are going to perform functional testing? Manual or automation testing? Are you going to execute all the test cases from your test management tool?
Which bug tracking tool are you going to use? What will be the process when you find a new bug?
What are your test entry and exit criteria?
How will you track your testing progress? What metrics are you going to use for tracking test completion?
Task distribution – Define the roles and responsibilities of each team member.
What documents will you produce during and after the testing phase?
What risks do you see in Test completion?
