Currently, the mock OpenVR client we are using for VR browser tests is about as minimal as possible, with no way to change orientation, position, or anything related to controllers. Eventually we'll want to set returned values arbitrarily during tests to get test coverage equivalent to the instrumentation tests. This will require some sort of IPC mechanism since OpenVR is a separate process.
