This is a testharness.js-based test.
[FAIL] setRemoteDescription() on offer with a=identity should establish peerIdentity
  promise_test: Unhandled rejection with value: object "TypeError: pc1.setIdentityProvider is not a function"
[FAIL] setRemoteDescription() on offer with a=identity that resolve to value different from target peer identity should reject with OperationError
  promise_test: Unhandled rejection with value: object "TypeError: pc1.setIdentityProvider is not a function"
[FAIL] setRemoteDescription() with peerIdentity set and with IdP proxy that return validationAssertion with mismatch contents should reject with OperationError
  pc1.setIdentityProvider is not a function
[FAIL] setRemoteDescription() and peerIdentity should reject with OperationError if IdP return validated identity that is different from its own domain
  pc1.setIdentityProvider is not a function
[FAIL] When IdP throws error and pc has target peer identity, setRemoteDescription() and peerIdentity rejected with RTCError('idp-execution-error')
  pc1.setIdentityProvider is not a function
[FAIL] IdP failure with no target peer identity should have following setRemoteDescription() succeed and replace pc.peerIdentity with a new promise
  pc1.setIdentityProvider is not a function
