Change this to a LoggingX?

 
-    CheckedReadFD(ReadPipeFD(), &c, 1);
+    // Use LoggingReadFD() instead of CheckedReadFD() for the first read so that
+    // the test can fail gracefully with a gtest assertion if the child does not
+    // execute properly.
+    ASSERT_TRUE(LoggingReadFD(ReadPipeFD(), &c, 1));
     EXPECT_EQ('Z', c);
   }
