Creating a Test Strategy from Scratch

A test strategy is a high-level document that defines the testing approach for a project. Unlike a test plan (which is detailed and project-specific), a strategy provides the overarching framework that guides all testing activities.

When You Need a Test Strategy

  • Starting a new project or product
  • Joining a company with no existing QA processes
  • Major architectural changes (monolith to microservices)
  • Entering a new domain (healthcare, fintech, etc.)
  • Scaling from startup to growth stage

The Test Strategy Framework

1. Context Analysis

Before writing anything, understand:

  • Product: What does it do? Who uses it? What platforms?
  • Architecture: Monolith, microservices, serverless?
  • Team: Size, skills, experience levels?
  • Risk: What happens if quality fails? Regulatory requirements?
  • Constraints: Timeline, budget, existing technical debt?

2. Scope Definition

Define what will and will not be tested:

In ScopeOut of ScopeRationale
Core user workflowsThird-party integrations (tested by vendor)Focus on what we control
API contractsInfrastructure (handled by DevOps)Separation of concerns
Cross-browser (Chrome, Firefox, Safari)IE110.1% user base
Performance under expected loadDisaster recoveryPhase 2 priority

3. Testing Approach by Level

graph TD U[Unit Tests 70%] --> I[Integration Tests 20%] I --> E[E2E Tests 10%] style U fill:#22c55e style I fill:#3b82f6 style E fill:#ef4444

Unit tests (70%): Developers write, run on every commit, fast feedback Integration tests (20%): API contracts, service interactions, database queries E2E tests (10%): Critical user journeys only, run in staging

4. Tool Selection

6. Risk Mitigation

Identify top risks and their mitigation:

Performance degradationHighHighWeekly load tests, performance budgets
Security breachMediumCriticalOWASP top 10 checks, quarterly pen tests

Template: One-Page Test Strategy

For smaller projects, a one-page strategy is sufficient:

PROJECT: [Name]
DATE: [Date]
AUTHOR: [QA Lead]

SCOPE: [3-5 bullet points of what's in scope]
OUT OF SCOPE: [2-3 items explicitly excluded]

APPROACH:
- Unit: [Developer-owned, X% coverage target]
- API: [Tool, critical endpoints, frequency]
- E2E: [Tool, critical journeys, environments]
- Performance: [Tool, targets, frequency]

ENVIRONMENTS: [List with purposes]
TOOLS: [Key tools and rationale]
RISKS: [Top 3 risks with mitigation]
SUCCESS CRITERIA: [DRE target, coverage targets, release quality goals]

Exercise

Apply the concepts from this lesson to your current or recent project. Document your approach and results.

Guidance

Consider how test strategy for a new project applies to your specific context. What would you do differently based on what you learned?

Pro Tips

Tip 1: Start small and iterate. Do not try to implement everything at once.

Tip 2: Get buy-in from stakeholders before making major process changes.

Tip 3: Measure the impact of your changes to demonstrate value.

Key Takeaways

  • Test Strategy for a New Project is essential for QA career growth beyond individual contributor level
  • Start with assessment and quick wins before major transformations
  • Tailor your approach to your organization’s context and maturity
  • Measure and communicate the impact of your improvements
  • Continuous improvement is more effective than one-time overhauls
