List of tests

At ingress

• Supports CE 0.3 or CE 1.0 via HTTP
• Supports structured or Binary mode
• Respond with 2xx on good CE
• Respond with 400 on bad CE
• Reject non-POST requests to publish URI

At consumer

• No upgrade of version
• Attributes received should be the same as produced (attributes may be added)
• Events are filtered
• Events are delivered to multiple subscribers
• Deliveries succeed at least once
• Replies are accepted and delivered
• Replies that are unsuccessfully forwarded cause initial message to be redelivered (Very difficult to test, can be ignored)

• Trace header on incoming event is preserved for subscribers and propagated to reply events
• Metrics are supported (Difficult to test, can be ignored)
