OneRoster 1.0 Conformance Testing System for a Service Consumer/Client is located at: http://173.204.22.251:8080/oneroster-client-cts-webapp/

Service Consumer testing requires the Implementation Under Test (IUT) to send a set of OneRoster HTTP messages to the IMS OneRoster Conformance Test System. This requires the IUT to use the supplied unique Consumer Key/Secret for authentication.

The Test System displays which tests have been run, failed or passed.

The Test System displays which tests have been run, failed or passed. Here the system has passed ALL of the tests and thus Certification.

A summary of the results before the testing has begun i.e. before messages from the Sensor under test have been sent to the Caliper Conformance Test System. Note that NOT ALL of

the actions are required to obtain certification i.e. only those marked with an ‘*’.

A summary of the results during testing i.e. messages from the Sensor under test have been sent to the Caliper Conformance Test System.

This report shows that the Sensor under test will be certified as supporting the following Metric Profiles: •  Assessment •  AssessmentItem •  Annotation •  Assignable

25/08/16

The test system provides a log of the messages received from the Sensor under test. Here is the payload for the Bookmarked action of the AnnotationEvent.
