Suggest moving these down to the protected section, and having the test fixture
expose them.  Also, I don't believe they need to be virtual.

+  bool handled() const { return handled_; }
+
+ protected:
+  // Only used in tests.
+  void set_ssl_interstitial_display_delay(base::TimeDelta delay) {
+    ssl_interstitial_display_delay_ = delay;
+  }
+  base::OneShotTimer<SSLErrorHandler> timer_;

Rather than making timer_ protected (Which Google style guide technically
forbids), suggest making it private, and making a protected method
IsTimerRunning.  Then just have the test fixture expose that.

Done.
