// This test verifies that SWC configuration is properly set up for:
// 1. Stimulus controller class name preservation (keepClassNames: true)
// 2. React 19 compatibility (automatic runtime)
//
// NOTE: We don't import swc.config.js directly in tests because it requires
// Node.js modules (path, fs) that aren't available in Jest environment.
// The actual SWC configuration is verified through build process and manual testing.

it('documents required SWC settings for Stimulus controllers', () => {
// This test serves as documentation for the required SWC configuration.
// The actual settings are in config/swc.config.js:
//
// jsc: {
// keepClassNames: true, // Required for Stimulus controller discovery
// loose: false, // Required for Stimulus to work correctly
// transform: {
// react: {
// runtime: 'automatic', // React 19 compatibility
// development: env.isDevelopment, // Better dev error messages
// refresh: env.isDevelopment && env.runningWebpackDevServer,
// },

⚠️ Potential issue | 🟠 Major

Reconsider the approach: tests should validate, not just document.

This file has several concerns:

  1. Misleading filename: The file is named comments_controller.spec.js but doesn't test a comments controller.
  2. Documentation disguised as a test: Using a test file solely for documentation is an anti-pattern. The test always passes (expect(true).toBe(true)), providing no actual validation of the SWC configuration.
  3. Maintenance burden: The documentation here can easily become stale if config/swc.config.js is updated but this file isn't.

Consider these better alternatives:

Option 1 (Recommended): Write an actual validation test

Rename the file to swc_config.spec.js and write a test that validates the actual configuration:

// client/app/config/swc_config.spec.js
const path = require('path');

describe('SWC Configuration', () => {
  it('has required settings for Stimulus and React 19', () => {
    // This runs in Node.js test environment, so we can require the config
    const swcConfig = require(path.resolve(__dirname, '../../../config/swc.config.js'));
    
    // Validate Stimulus requirements
    expect(swcConfig.jsc.keepClassNames).toBe(true);
    expect(swcConfig.jsc.loose).toBe(false);
    
    // Validate React 19 requirements
    expect(swcConfig.jsc.transform.react.runtime).toBe('automatic');
  });
});

Option 2: Document in markdown

Create docs/SWC_CONFIGURATION.md explaining the required settings and why they're needed.

Option 3: Add JSDoc comments

Document these requirements directly in config/swc.config.js using JSDoc comments.

Would you like me to generate a complete implementation for Option 1?

In client/app/controllers/comments_controller.spec.js lines 1-28: this test file
is misnamed and contains only a passing placeholder used as documentation, which
is an anti-pattern; rename the file to client/app/config/swc_config.spec.js (or
move it under a more appropriate test directory), replace the placeholder with a
real Node.js test that requires the actual config (use path.resolve to require
../../../config/swc.config.js) and add assertions to validate
swcConfig.jsc.keepClassNames === true, swcConfig.jsc.loose === false and
swcConfig.jsc.transform.react.runtime === 'automatic'; alternatively, if you
prefer documentation only, delete this test and add a docs/SWC_CONFIGURATION.md
or JSDoc comments in config/swc.config.js explaining the settings.
