The OC4 Interop contains two separate types of tests:
Cross Solution Tests
Cross Solution Tests test general interoperability between two different solutions, with the goal of having every solution interact with every other solution, so that any incompatibilities will come to light.

Feature Tests produce results that are valid for a single solution, describing situations that test the solution's ability to support specific features.
Feature Test Results for any given solution can be viewed within the Solution Page, or overall results can be viewed at:
