b2c-developer-tooling: Skill for Claude Code

Testing

This skill covers project-specific testing patterns for the B2C CLI project.

Test Framework Stack

• Test Runner: Mocha
• Assertions: Chai (property-based)
• HTTP Mocking: MSW (Mock Service Worker)
• Stubbing/Mocking: Sinon
• Code Coverage: c8
• TypeScript: tsx (native execution without compilation)

Running Tests

For coding agents (minimal output - only failures shown):

# Run tests - only failures + summary
pnpm run test:agent

# Run tests for specific package
pnpm --filter @salesforce/b2c-tooling-sdk run test:agent
pnpm --filter @salesforce/b2c-cli run test:agent

For debugging (full output with coverage):

# Run all tests with coverage
pnpm run test

# Run tests for specific package
pnpm --filter @salesforce/b2c-tooling-sdk run test
pnpm --filter @salesforce/b2c-cli run test

# Run single test file (no coverage, faster)
cd packages/b2c-tooling-sdk
pnpm mocha "test/clients/webdav.test.ts"

# Run tests matching pattern
pnpm mocha --grep "mkcol" "test/**/*.test.ts"

# Watch mode for TDD
pnpm --filter @salesforce/b2c-tooling-sdk run test:watch

Test Organization

Tests mirror the source directory structure with .test.ts suffix:

packages/b2c-tooling-sdk/
├── src/
│   └── clients/
│       └── webdav.ts
└── test/
    └── clients/
        └── webdav.test.ts

Import Patterns

Always use package exports, not relative paths:

// Good - uses package exports
import { WebDavClient } from '@salesforce/b2c-tooling-sdk/clients';
import { OAuthStrategy } from '@salesforce/b2c-tooling-sdk/auth';

// Avoid - relative paths
import { WebDavClient } from '../../src/clients/webdav.js';

This ensures tests use the same export paths as consumers.

Config Isolation

Tests that check for "missing credentials" or "no config" scenarios need isolation from the developer's real configuration files (~/.mobify, dw.json) and environment variables.

Using Config Isolation Helpers

import { isolateConfig, restoreConfig } from '../helpers/config-isolation.js';

describe('config-dependent tests', () => {
  beforeEach(() => {
    isolateConfig();
  });

  afterEach(() => {
    restoreConfig();
  });

  it('handles missing credentials', async () => {
    // Test now runs without reading real ~/.mobify or SFCC_* env vars
  });
});
