| 2 | | * Smoke test: launches Electron with the production build, |
| 3 | | * waits for the page to render, checks for console errors, and exits. |
| 2 | * Smoke test: builds desktop + renderer, launches Electron against the |
| 3 | * production bundle, waits for the renderer to confirm it loaded, then exits. |
| 4 | * |
| 5 | * Catches the two categories of regression we've hit: |
| 6 | * 1. Module resolution failures (preload can't find @acme/contracts, etc.) |
| 7 | * 2. CSP / script blocking (React fails to mount) |
| 8 | * |
| 9 | * The test works by injecting a tiny check via ELECTRON_ENABLE_LOGGING — |
| 10 | * Electron forwards renderer console.log to the main process stdout when |
| 11 | * that env var is set. We look for React's "Download the React DevTools" |
| 12 | * message as proof that React successfully mounted (it only fires after |
| 13 | * the first render). For production mode (no React DevTools message), we |
| 14 | * instead check that no fatal errors appeared. |
