/* We optionally spin-up services based on the testing mode:
 *
 * Local Development:
 * - If running locally (developer mode), we run "vite dev" with HMR enabled
 * - This allows playwright to monitor the code for changes
 * - WORKERS = 1 (to avoid conflicts with HMR)
 *
 * CI Mode (Production):
 * - In CI (GitHub actions), we run "vite build" to generate a production build
 * - This build is then served by a local server for testing
 * - This allows the tests to run much faster and with parallel workers
 * - WORKERS = MAX_WORKERS (to speed up the tests)
 *
 * CI Mode (Coverage):
 * - In coverage mode (GitHub actions), we cannot compile the code first
 * - This is because we need to compile coverage report against ./src directory
 * - So, we run "vite dev" with coverage enabled (similar to the local dev mode)
 * - WORKERS = 1 (to avoid conflicts with HMR)
