SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This guide helps developers design robust tests by detailing what to test, how to assert, and how to mock, while avoiding common anti-patterns.

Core Features & Use Cases

  • Decision-tree guided test planning for unit, integration, and end-to-end tests.
  • Clear naming conventions and assertion guidelines to improve readability and maintenance.
  • Comprehensive mocking strategies and anti-pattern avoidance with real-world examples.
  • Use case: Apply these patterns when building test suites for UI interactions, API endpoints, and data validation.

Quick Start

Create a unit test following the naming convention and include at least one assertion with a mocked dependency where applicable.

FAQPage Schema
How do I design structured unit tests that avoid common anti-patterns?

To design structured unit tests, follow decision-tree guided test planning that establishes clear naming conventions, robust assertions, and effective mocking to avoid common anti-patterns. This approach improves readability and maintenance across your test suite.

What is the best way to create a mocking strategy for API endpoints and data validation?

The best way to create a mocking strategy is to apply comprehensive patterns that isolate dependencies for API endpoints and data validation. Use real-world examples to enforce best practices and avoid anti-patterns during test execution.

How do I plan testing strategies across unit, integration, and end-to-end tests?

Plan testing strategies by using a decision-tree guide to determine what to test across unit, integration, and end-to-end tests. This structured approach ensures you apply consistent naming conventions and appropriate assertions for each test scope.

When should I use mocking versus real dependencies in test design?

Use mocking in test design when you need to isolate components and control dependency behavior for reliable assertions. Apply comprehensive mocking strategies to avoid anti-patterns, using real dependencies only when integration or end-to-end coverage is required.

What naming conventions should I follow to improve test readability and maintenance?

Follow clear naming conventions that describe the specific scenario and expected outcome to improve test readability and maintenance. Consistent naming across unit and integration tests ensures structured documentation and easier anti-pattern avoidance.
