@ovh-ux/manager-tests-setup

Shared unit test configuration for OVHcloud Manager apps
Modular, hexagonally-structured test infrastructure layer
Promotes consistency, reuse, and decoupling across 30+ React applications

Overview

@ovh-ux/manager-tests-setup centralizes test configuration (unit, integration, and future test layers) for all OVHcloud Manager apps. It provides:

• A reusable, opinionated sharedConfig for unit and integration testing
• Exports (createConfig, mergeConfig, defaultCoverageConfig) to decouple applications from test runner internals
• A CLI tool (manager-test) for seamless test execution—no need to locally install or configure the test runner

The setup follows Hexagonal Architecture principles, ensuring test logic remains isolated from application code and tooling can evolve independently.

Installation

In the OVHcloud Manager monorepo:

yarn add -D @ovh-ux/manager-tests-setup

Usage

Each app consumes the shared configuration by combining sharedConfig with local overrides via mergeConfig.

Example: vitest.config.js

import path from 'path';
import {
  sharedConfig,
  createConfig,
  mergeConfig,
  defaultCoverageConfig,
} from '@ovh-ux/manager-tests-setup';

export default mergeConfig(
  sharedConfig,
  createConfig({
    test: {
      setupFiles: ['./src/setupTests.ts'],
      coverage: {
        exclude: ['src/specific/setup.ts', ...defaultCoverageConfig.exclude],
      },
    },
    resolve: {
      alias: {
        '@': path.resolve(__dirname, 'src'),
      },
    },
  }),
);

CLI: manager-test

A unified CLI wrapper for executing tests without requiring per-app test runner dependencies:

yarn manager-test

Supported flags:

yarn manager-test run --coverage
yarn manager-test --ui

Applications do not need to install vitest, @vitejs/plugin-react, or @vitest/coverage-v8 individually.

Exports API

Export	Description
sharedConfig	Base configuration (includes jsdom, React plugin, coverage)
createConfig()	Factory to create custom config fragments (wraps defineConfig)
mergeConfig()	Merges shared and local config (wraps mergeConfig from Vitest)
defaultCoverageConfig	Shared defaults for coverage settings (excludes, reporters, etc.)

Architectural Principles

This package follows Hexagonal Architecture:

• Ports: createConfig, mergeConfig, defaultCoverageConfig
• Adapters: Vitest, Vite, React plugin
• Applications remain independent of the underlying testing technology except for strongly coupled APIs like vi.mock, after*, or before*.

Benefits

• Centralized maintenance and upgrades
• Consistent test behavior across projects
• Easy future migration (e.g., to vitest/browser or Jest)
