nit:  const should go on same line as close paren, so I suggest:

SecurityInterstitialPage::Type
CaptivePortalBlockingPage::GetTypeForTesting() const {

Done.

Can we just not include this file when it's not enabled?  I seem to recall this
being discussed before, but I could be misremembering.

+  CaptivePortalTabHelper::OpenLoginTabForWebContents(web_contents(), true);
