// RAII type that installs new AutofillManagers of type `T` in all newly
// navigated frames in all newly created WebContents.
//
// The injector only injects an AutofillManager if a driver is created.
// Especially in unit tests it may be necessary to do a navigation to create the
// driver, for example with
//   NavigateAndCommit(GURL("about:blank"))
// or force-create the driver manually with
//   client->GetAutofillDriverFactory().DriverForFrame(rfh).
//
// To prevent hard-to-find bugs, only one TestAutofillManagerInjector may be
// alive at a time. It must not be created before a TestAutofillClientInjector.
// These conditions are CHECKed.
//
// Usage:
//
//   class AutofillFooTest : public ... {
//    public:
//     class MockAutofillManager : BrowserAutofillManager {
//      public:
//       explicit MockAutofillManager(ContentAutofillDriver* driver)
//           : BrowserAutofillManager(driver, "en-US") {}
//       MOCK_METHOD(...);
//       ...
//     };
//
//     MockAutofillManager* autofill_manager(content::RenderFrameHost* rfh) {
//       return autofill_manager_injector_[rfh];
//     }
//
//    private:
//     TestAutofillManagerInjector<MockAutofillManager>
//         autofill_manager_injector_;
