Testing Strategies

A list of best practices and methodologies for Testing Strategies. Learn about basic concepts, benefits, challenges, and implementation methods for each practice.

Test Pyramid

intermediate

Model showing the appropriate ratio of unit, integration, and E2E tests. A hierarchical structure that builds upon low-cost, fast tests as a foundation for progressively more comprehensive testing.

Benefits

  • Fast feedback
  • Cost efficiency
  • Reliability assurance

Key Principles

  • 70% Unit
  • 20% Integration
  • 10% E2E

Jest, Selenium, Cypress, TestNG

Test-Driven Development

intermediate

Development methodology where tests are written before implementing functionality. Improves quality and code design through Red-Green-Refactor cycles.

Benefits

  • Improved code quality
  • Better design
  • Safe refactoring

Key Principles

  • Red: Write failing test
  • Green: Minimal implementation
  • Refactor: Improve

JUnit, RSpec, Mocha, Pytest

Contract Testing

advanced

Method to define service communication interfaces as contracts, allowing providers and consumers to test independently. Ensures integration quality between microservices.

Benefits

  • Independent development
  • Early integration issue detection
  • API compatibility assurance

Key Principles

  • Consumer-driven
  • Contract sharing
  • Bidirectional verification

Chaos Engineering

advanced

Practice of intentionally introducing failures in production to verify and improve system resilience. Enhances system reliability against unexpected failures.

Benefits

  • Improved system resilience
  • Enhanced failure response
  • Reliability verification

Key Principles

  • Define hypothesis
  • Minimal blast radius
  • Continuous experimentation

Shift-Left Testing

intermediate

Approach that moves testing earlier in the development process to detect issues early and reduce fix costs. Promotes a culture of building quality from the start.

Benefits

  • Early bug detection
  • Reduced fix costs
  • Improved quality

Key Principles

  • Early integration
  • Automation first
  • Continuous feedback
