Key Concepts

End-to-End Testing

Validates complete user journeys:

• User perspective (UI interaction)

• Complete workflows

• Real data scenarios

• Multiple system components

See: End-to-End Testing Guide

Cross-Platform Validation

Ensures consistency across platforms:

• Multiple browsers

• Different devices (desktop, tablet, mobile)

• Various OS (Windows, macOS, Linux, iOS, Android)

• Network conditions

See: Cross-Platform Validation Guide

Integration Testing

Validates system components working together:

• API to API communication

• Database integration

• Third-party services

• Service dependencies

See: Integration Testing Guide

Regression Testing

Prevents previously-fixed bugs from reappearing:

• Automated test suites

• Per-release validation

• Quick feedback loops

• Continuous integration

See: Regression Testing Guide

Smoke Testing

Quick health checks and early issue detection:

• Core functionality only

• Quick execution (minutes)

• Daily/pre-deployment checks

• Early problem detection

See: Smoke Testing Guide

API Workflow Testing

Complex API sequences and business logic:

• Multi-step API scenarios

• Data dependencies between calls

• State management

• Complex workflows

See: API Workflow Testing Guide

Workflow Implementation Patterns

Pattern 1: Simple Sequential Test

[Setup]
  ↓
[Execute test steps]
  ↓
[Verify results]
  ↓
[Cleanup]
  ↓
[Report]

Pattern 2: Data-Driven Test

[Load test data]
  ↓
FOR each test case:
  [Execute with data]
  [Verify results]
  [Record outcome]
  ↓
[Aggregate results]
  ↓
[Report]

Pattern 3: Multi-Platform Testing

[Test Scenario A]
        ↓
[Test Scenario B]
        ↓
[Test Scenario C]
        ↓
[Aggregate Results]
        ↓
[Report]

Pattern 4: Conditional Testing

[Check environment]
  ↓
IF production:
  [Safety checks]
ELSE:
  [Skip safety]
  ↓
[Execute tests]
  ↓
[Report]

Best Practices Summary

✅ Universal Do's

• Start with smoke tests - Quick validation

• Layer testing approach - Pyramid strategy

• Automate early - ROI improves over time

• Monitor performance - Track execution times

• Version test data - Control test conditions

• Document assumptions - Future reference

• Review regularly - Update as system changes

• Fail fast - Stop at first issue when appropriate

❌ Universal Don'ts

• Don't test everything with E2E - Too slow

• Don't ignore flaky tests - Fix root cause

• Don't skip cleanup - Data accumulates

• Don't test UI for logic - Use API tests

• Don't ignore failures - Investigate always

• Don't hardcode test data - Use variables

• Don't stop improving - Iteration matters

• Don't test without purpose - Know what you're validating
