Maybe document that the service runs in the same process? Would it be difficult
to run it in a separate process?

[hashimoto, 2016/01/13 05:46:46]

I'm not sure if there is any test running in a different process.
As opening two FDs of /dev/binder is enough to let the driver think the test is
running in a separate process, actually there is no need to do that.

Then how about documenting that the service runs in the same process and it's
sufficient because opening two FDs of /dev/binder is enough to let the driver
think the test is
running in a separate proces?

Added a note.

+  ~TestService();
+
+  // The name of this service.
+  const base::string16& service_name() const { return service_name_; }
+
+  // Starts and waits for the service to start.

[satorux1, 2016/01/13 04:33:20]

please document the return value.

[hashimoto, 2016/01/13 05:46:46]

Done.
