Can you move these right after "navigation_controller", so that the declaration
is directly proximate to the initialization?

+  navigation_controller.SetNavigationFeatureForTesting(&feature);
+
+  EXPECT_CALL(observer1, OnNavigationStateChanged()).Times(1);
+  EXPECT_CALL(observer2, OnNavigationStateChanged()).Times(2);
+
   navigation_controller.LoadURL(kExampleURL);
   loop.RunUntilIdle();
 
   EXPECT_EQ(kExampleURL, navigation_controller.GetURL());
-  EXPECT_EQ(kExampleURL, observer1.GetLastURL());
-  EXPECT_EQ(kExampleURL, observer2.GetLastURL());
 
   // Observer should no longer receive callbacks.
   blimp_contents.RemoveObserver(&observer1);
 
   navigation_controller.LoadURL(kOtherExampleURL);
   loop.RunUntilIdle();
 
   EXPECT_EQ(kOtherExampleURL, navigation_controller.GetURL());
-  EXPECT_EQ(kExampleURL, observer1.GetLastURL());
-  EXPECT_EQ(kOtherExampleURL, observer2.GetLastURL());
