Test Strategy is a high-level document that defines the overall approach for testing an application in a structured and documented manner. It outlines goals, methods, and guidelines for the entire Software Testing Life Cycle (STLC) and acts as a reference for detailed test plans.
- Describes the complete testing approach and process
- Specifies testing techniques, modules, and types of testing
- Defines entry and exit criteria for testing phases
- Provides guidelines for automation and resource planning
Components of Test Strategy
1. Release Control
Defines how builds, deployments, and releases are managed across testing environments to ensure consistency.
- Maintains version history and release strategy
- Defines build deployment process
- Assigns deployment responsibilities
- Avoids mismatched or unplanned releases
2. Risk Analysis
Risk Analysis identifies potential risks that may impact testing or project delivery. It also provides strategies to minimize and handle those risks effectively.
- Lists all possible risks
- Provides mitigation strategies
- Defines contingency plans
- Assigns ownership for each risk
3. Review & Approvals
This component ensures that the test strategy document is reviewed and approved by all stakeholders. It helps maintain alignment and accountability across teams.
- Lists teams involved (Admin, PM, Dev, Business)
- Defines review and approval process
- Ensures stakeholder agreement
4. Testing Tools
Testing Tools section defines the tools required for test execution, management, and automation. It helps in selecting the right tools for efficient testing.
- Identifies automation and test management tools
- Includes performance and security testing tools
- Mentions open-source or commercial tools
- Defines licenses or user capacity
5. Scope and Overview
Scope and Overview provides a high-level summary of the project and testing objectives. It defines the purpose, scope, and users of the test strategy document.
- Describes project overview
- Defines document users
- Specifies testing activities and phases
- Aligns testing with project timeline
6. Testing Methodology
Testing Methodology explains the overall testing approach, including levels, processes, and team responsibilities. It ensures a structured and consistent testing process.
- Covers testing types (unit, integration, system, etc.)
- Defines roles and responsibilities
- Explains testing approach and objectives
- Specifies timelines and ownership
7. Test Environment Specification
This section describes the setup and requirements of testing environments. It ensures a stable and reliable environment for executing test cases.
- Defines environment configurations
- Specifies hardware and software requirements
- Explains test data preparation
- Includes backup and recovery procedures
Types Test Strategy
The following are the different types of test strategies:
1. Analytical Strategy
Analytical strategy is based on analyzing requirements, risks, or specifications to derive test conditions. It ensures traceability between requirements and testing activities.
- Uses risk-based and requirements-based testing
- Derives test cases from detailed analysis
- Tracks results against requirements coverage
- Ensures traceability and validation
2. Model-Based Strategy
Model-based strategy uses system models to represent behavior and derive test cases. It is useful for complex systems and performance/load testing.
- Builds models of system behavior and processes
- Considers inputs, outputs, and data flows
- Simulates real-world scenarios
- Useful for load and performance testing
3. Methodical Strategy
Methodical strategy follows predefined checklists and standards for testing. It ensures consistency and repeatability in the testing process.
- Uses standards like ISO 25000
- Relies on predefined checklists
- Suitable for security and maintenance testing
- Reduces dependency on individual tester creativity
4. Standards or Process-Compliant Strategy
This strategy strictly follows industry standards or regulatory guidelines. It is commonly used in regulated domains where compliance is mandatory.
- Follows standards like FDA guidelines
- Defines test cases based on approved processes
- Used in regulated industries
- Ensures compliance and audit readiness
5. Reactive Strategy
Reactive strategy is based on experience and real-time system behavior. Testing is performed dynamically after the software is available.
- Relies on exploratory testing
- Tests are created during execution
- Uses test charters for guidance
- Suitable for Agile environments
6. Consultative Strategy
Consultative strategy involves stakeholders in defining testing scope and priorities. It ensures that testing aligns with business and user expectations.
- Takes input from stakeholders and users
- Uses prioritized requirements
- Applies techniques like equivalence partitioning
- Aligns testing with business needs
7. Regression-Averse Strategy
Regression-averse strategy focuses on preventing regression defects after changes. It ensures stability of the application through repeated and automated testing.
- Uses automated regression test suites
- Runs tests on every build or update
- Covers functional and non-functional scenarios
- Prevents breaking existing functionality
Test Strategy Selection
Test Strategy Selection is the process of choosing the most suitable testing approach based on project requirements, risks, and resources. It ensures that testing is efficient, effective, and aligned with business goals.
- Based on project size, complexity, and requirements.
- Considers risks, critical functionalities, and priorities.
- Depends on available resources, tools, and team expertise.
- Aligns testing approach with timelines and delivery goals.
Details Included in Test Strategy Document
A Test Strategy Document defines the overall approach and guidelines for testing activities in a project. It provides a structured plan to ensure effective testing aligned with business and technical requirements.
- Testing Scope & Objectives: Defines what will be tested and the goals of testing.
- Test Approach & Types: Describes testing levels, techniques, and methods to be used.
- Tools & Environment: Specifies testing tools, frameworks, and environment setup.
- Roles, Risks & Deliverables: Includes team responsibilities, risk management, and expected outputs.
Test Strategy Vs Test Plan
| Test Plan | Test Strategy |
|---|---|
| It's developed from a set of software requirements (SRS). | It comes from a Business Requirement paper (BRS). |
| The test lead or manager is in charge of preparing it. | The project manager or the business analyst creates it. |
| The components include the test plan's id, features to be tested, test techniques, testing tasks, features pass or fail criteria, test deliverables, responsibilities, and timetable, among others. | The components of a test strategy include objectives and scope, documentation formats, test processes, team reporting structure, client communication strategy, and so on. |
| After the requirements have been approved, the test plan is written. | The test strategy comes first, followed by the test plan. |
| It should be simple and straightforward. | The test approach serves as a general guide for the project at hand. |
