This page is a summary of QA practices to test instrumentation.

Before testing
- read documentation on event logging (there could be updates/changed access info etc) - Analytics/Systems/EventLogging/TestingOnBetaCluster

- read a schema description (e.g. Schema:HomepageModule or find a schema on shema.wikimedia.org) to understand what actions to perform to trigger eventlogging events

- create a testing outline based on a phab task (e.g. ) or on a schema description to make sure that all events from a schema would be triggered

Monitoring
- in beta cluster: stream-beta.wmflabs.org

- on production, e.g. for GrowthExperiments schemas - Growth event validation

In a browser (client side testing)
The testing with the console snippets can be done in beta cluster and in production.

- enable your browser's devtools and  enable "persistent log" in the Console

- use the following snippet (credit to User:KHarlan (WMF)

- perform the actions that trigger eventlogging and compare with the info documented in the relevant schema description

Server side testing
The instructions are for beta cluster.

- log in and go to the directory with logs:

- to verify that events have been properly logged you may use  or any other means of your choice. For example, to see which editor_interface were recorded, you may use:
