Alerting

Trait that contains the alert method, which can be used to send an alert to the reporter.

One difference between alert and the info method of Informer is that info messages provided during a test are recorded and sent as part of test completion event, whereas alert messages are sent right away as AlertProvided messages. For long-running tests, alert allows you to send "alert notifications" to the reporter right away, so users can be made aware of potential problems being experienced by long-running tests. By contrast, info messages will only be seen by the user after the test has completed, and are more geared towards specification (such as Given/When/Then messages) than notification.

The difference between alert and the update method of Updating is that alert is intended to be used for warnings or notifications of potential problems, whereas update is just for status updates. In string reporters for which ANSI color is enabled, update notifications are shown in green and alert notifications in yellow.
