EXPECT_FALSE(job->transaction_);?

Done.

+
+  req.SetPriority(MEDIUM);
+  // |req| doesn't know about |job|, so propagate the SetPriority call
+  // manually.
+  job->SetPriority(MEDIUM);
+
+  job->Start();
+  EXPECT_TRUE(job->transaction_ != NULL);

EXPECT_TRUE(job->transaction_);?

Think it's a little weird to use != NULL here, and "!job->transaction_" above,
instead of == NULL.

EXPECTing on the raw pointer values should also provide a little more
information in debug output.

I think I'm just paranoid of how various compilers handle implicit conversion to
bool. We'll see if this blows up on Windows or Android.  Done.
