literal bool argument is not good for code readability.
If we'll add more literal bool for this argument , we should change the argument
an enum. Otherwise, please add a code comment or a constant symbol.  e.g.
   didAddInputPort(...., true /* active */);

   const bool active = true;
   didAddInputPort(..., active);

Done.

   client_->didAddOutputPort("MockOutputID",
                             "MockOutputManufacturer",
                             "MockOutputName",
-                            "MockOutputVersion");
+                            "MockOutputVersion",
+                            true);
   interfaces_->GetDelegate()->PostTask(new DidStartSessionTask(
       this, client_, interfaces_->GetTestRunner()->midiAccessorResult()));
 }
