Problem

When running npm run test:unit, karma was not finding or executing any spec files. The test runner would start, the browser would connect, but no tests would be discovered or run.

Root Cause

The Angular testing environment initialization was commented out in src/test.ts (introduced in commit 143cde7). Without calling getTestBed().initTestEnvironment(), the Angular TestBed framework is never configured, preventing karma from properly discovering and executing the 31+ spec files in the project.

Changes

1. Restore Angular Testing Environment Initialization (src/test.ts)

// Added required imports
import { getTestBed } from '@angular/core/testing';
import {
  BrowserDynamicTestingModule,
  platformBrowserDynamicTesting
} from '@angular/platform-browser-dynamic/testing';

// Uncommented the initialization call
getTestBed().initTestEnvironment(
  BrowserDynamicTestingModule,
  platformBrowserDynamicTesting()
);

This is the critical fix that enables karma to properly discover and execute Angular component tests.

2. Optimize Karma Configuration (src/karma.conf.js)

  • Increased browserNoActivityTimeout from 2 minutes to 5 minutes to accommodate the large application bundle (8.82 MB initial bundle)
  • Changed logLevel from LOG_DEBUG to LOG_INFO for less verbose output and improved performance

3. Enable Source Maps (angular.json)

  • Set sourceMap: true in the test configuration for better debugging capabilities during test execution

Testing

The fix has been validated by reviewing the git history and comparing with the standard Angular testing setup. The changes ensure that:

  • Angular TestBed is properly initialized before test discovery
  • Karma can find and load all spec files using require.context('./', true, /\.spec\.ts$/)
  • Tests can execute with adequate timeout for the large application bundle

This should resolve the GitHub Actions karma test step failure.

@copilot maybe some of the issues are related to this text on karmas website:

"Based on the current state of the web testing ecosystem, we have made the hard decision to deprecate Karma.

We know Karma is used particularly commonly in the Angular ecosystem, so Angular is adding Jest and Web Test Runner support to provide a migration path off of Karma. See the Angular blog for more details."

So we should migrate the tests to work with jest instead.

...

You're absolutely right that Karma is deprecated and migrating to Jest would be the best long-term solution.

My changes here fix the immediate issue (tests weren't discovering spec files due to missing TestBed initialization), which unblocks the current CI pipeline.

Migrating to Jest would be a separate effort involving:

  • Installing Jest and related Angular testing packages
  • Configuring jest.config.js
  • Updating package.json scripts
  • Potentially refactoring test files for Jest's different API
  • Updating CI workflows

Would you like me to create a separate issue/PR for the Jest migration, or should this PR include that work?

Yes, create issues, so we can migrate to jest with all the required changes to the project.

I don't have the ability to create GitHub issues directly. However, I can provide you with the detailed migration plan to create the issues yourself:

Issue 1: Migrate from Karma to Jest for unit testing

  • Install Jest and Angular Jest packages (@angular-builders/jest, jest, @types/jest)
  • Remove Karma dependencies (karma, karma-jasmine, karma-chrome-launcher, etc.)
  • Create jest.config.js with Angular-specific configuration
  • Update angular.json to use @angular-builders/jest builder instead of karma
  • Update package.json test scripts to use Jest
  • Convert test.ts to Jest setup file
  • Update tsconfig.spec.json for Jest compatibility
  • Verify all 31+ existing spec files work with Jest
  • Update GitHub Actions workflow to run Jest tests
  • Update TESTING.md and TESTING-QUICKSTART.md documentation

This migration will modernize the testing infrastructure and resolve the deprecated Karma issues.
