Usage:
|
|
./scripts/production-web-push-smoke.sh plan USER_EMAIL --check-only whoneedhelp.com
|
|
./scripts/production-web-push-smoke.sh prepare USER_EMAIL --confirm whoneedhelp.com
|
|
./scripts/production-web-push-smoke.sh verify --from-state --confirm whoneedhelp.com
|
|
./scripts/production-web-push-smoke.sh cleanup --from-state --confirm whoneedhelp.com
|
|
|
|
prepare sends one browser-only production Web Push notification to the newest
|
|
active Web Push device for USER_EMAIL. verify proves the exact Oban delivery
|
|
completed on its first attempt. cleanup removes only the run-scoped notification,
|
|
job, manifest, and temporary script. The separate phases leave time to inspect
|
|
and click the operating-system notification. No email worker, Android FCM device,
|
|
frozen test project, Caddy, or public Git is used.
