Testing Strategy

At DexaMinds, we don’t just write code — we engineer confidence. Testing is not an afterthought or a checkbox; it is a core pillar of how we deliver scalable, secure, and resilient software. Our testing strategy is designed to support rapid iteration without compromising stability, allowing us to move fast and ship with pride.

🎯 Objectives

  • Ensure functional correctness, security, and performance of our applications.
  • Enable fast feedback cycles through automation and continuous integration.
  • Promote a shared sense of ownership and accountability for product quality.
  • Encourage a test-first mindset to drive better architecture and design.

🧱 Testing Pyramid

We adopt a testing pyramid model that balances depth and speed, favoring a strong foundation of fast, reliable tests.

UI (End-to-End) Tests
 ────────────────────
Integration Tests
────────────────────
Unit Tests
────────────────────

1. Unit Tests (Foundation)

  • Purpose: Test individual functions, components, or classes in isolation.
  • Tools: Jest, Mocha, JUnit, PyTest (language-specific)
  • Best Practices:
  • Cover edge cases and logic branches.
  • Keep tests small, focused, and independent.
  • Mock external dependencies (APIs, databases).

2. Integration Tests

  • Purpose: Test interactions between modules (e.g., service layers and databases).
  • Tools: Supertest, Postman/Newman, SpringBootTest, Testcontainers
  • Best Practices:
  • Simulate real-world workflows.
  • Avoid excessive mocks to preserve integration realism.
  • Run regularly as part of CI.

3. End-to-End (E2E) Tests

  • Purpose: Validate entire user flows and system behavior from the end-user perspective.
  • Tools: Cypress, Playwright, Selenium
  • Best Practices:
  • Test critical paths (e.g., login, checkout, data entry).
  • Avoid flakiness by managing test data and dependencies.
  • Run on staging environments post-deployment.

🔁 Test Lifecycle in CI/CD

Testing is seamlessly integrated into our CI/CD pipelines to ensure continuous quality:

Stage Test Type Trigger
Pre-commit Linting, Unit Tests Developer local
Pre-push / CI Unit + Integration Tests GitHub Actions / CI pipeline
Pre-deploy E2E Tests Staging pipeline
Post-deploy Smoke Tests, Monitoring Production

🧪 Specialized Testing

🛡️ Security Testing

  • Automated tools: OWASP ZAP, Snyk, Dependency Scanners
  • Manual reviews for auth flows, role-based access, and input validation

⚡ Performance & Load Testing

  • Tools: k6, JMeter, Locust
  • Run against staging before release cycles or after architectural changes

🧬 Contract Testing

  • Tools: Pact, Dredd
  • Validates API agreements between microservices or frontend-backend interfaces

🧯 Chaos & Resilience Testing (optional but encouraged)

  • Tools: Gremlin, ChaosMonkey
  • Ensure services degrade gracefully under stress or failure conditions

✨ Culture of Testing

Testing is not just a responsibility — it’s a mindset:

  • Write tests as you write code, not afterward.
  • Prioritize readability — future you and your team will thank you.
  • Fail fast, fix fast — treat failed tests as opportunities to strengthen the system.
  • Celebrate test coverage, but never sacrifice quality for numbers.

✅ Test Coverage Goals

Type Minimum Coverage
Unit 80%+
Integration 60%+
E2E Critical flows only (measured by business impact)

Note: Quality > Quantity. 100% coverage with brittle or redundant tests can be more harmful than 80% meaningful coverage.

🧭 Conclusion

Our testing strategy ensures that every line of code we ship is reliable, maintainable, and ready for scale. In a fast-moving environment like DexaMinds, tests are not blockers — they are enablers. When we test well, we innovate with confidence.

Let’s continue to build boldly — with quality engineered at every step.
