SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Reliable testing strategies are difficult to implement consistently across Next.js App Router apps, leading to brittle deployments and missed regressions.

Core Features & Use Cases

  • Clear testing priorities for critical user flows, business logic, data validation, mutations, and rendering branches.
  • Structured test organization guidance for unit, integration, and end-to-end tests across features, routes, and server actions.
  • Naming, writing, and flaky-test rules to improve coverage without sacrificing maintainability.

Quick Start

Create a testing plan that matches the recommended project layout: place unit tests near feature code, maintain a dedicated e2e area, and apply the prioritized rules to new tests.

FAQPage Schema
How do I structure testing for Next.js App Router server actions?

Next.js App Router server actions testing requires placing unit tests near feature code and maintaining a dedicated e2e area. Apply prioritized rules to new tests to protect critical user flows, business logic, and data mutations.

What is the best way to prioritize tests for Next.js applications?

Prioritize Next.js application tests by focusing on critical user flows, business logic, data validation, mutations, and rendering branches. This strategy ensures robust coverage of essential App Router features without sacrificing maintainability.

How do I organize unit, integration, and e2e tests in a Next.js project?

Organize Next.js unit, integration, and e2e tests by matching the recommended project layout: place unit tests near feature code, maintain a dedicated e2e area, and apply structured naming conventions across all test types.

Does this testing strategy apply to route handlers and UI components in Next.js?

Yes, the testing strategy applies to route handlers and UI components in Next.js. It defines comprehensive unit, integration, and end-to-end scenarios across features, route handlers, and UI components within Next.js App Router projects.

How do I handle flaky tests and enforce naming conventions in Next.js?

Handle flaky tests and enforce naming conventions in Next.js by applying defined writing, naming, and flaky-test rules. This structured approach improves test coverage while maintaining project maintainability across features and server actions.
