There’s a variety of reasons why tests might not be completed successfully—from networking, firewalls, HTTP responses, incorrect markup to timeouts caused by poor performance. Ideally, we spot and address persistent failures quickly, so there’s no disruption to our monitoring and data.
For that exact reason, we introduced Snapshot Failure Emails that alert you when tests are not completing. We will also let you know when tests are running smoothly again.
See detailed information about why your test might not have completed successfully.
Anyone can subscribe to Snapshot Failure alerts in Profile → Email Notifications. In case you didn’t see it, we also documented the most common test error types, so you can debug the reasons behind failures more quickly, too.
