You are using a strange paradigm here. Even though the class has "TestBase" in
its name, it does not pull in |InProcessBrowserTest|. Test fixtures are expected
to inherit from this class and another one that actually provides the base
|InProcessBrowserTest|. If you really do not want to be pulling
|InProcessBrowserTest| into this class, then I think it should be turned into a
helper you instantiate, not a base you inherit from (i.e. composition, not
inheritance).

+ public:
+  SettingsProviderTestBase();
+
+  // In some cases it is required to pass |create_settings_service| as false:
+  // if the test already has a device settings service and/or CrosSettings set
+  // up by another bundle, creating another one causes crash.
+  explicit SettingsProviderTestBase(bool create_settings_service);
+  virtual ~SettingsProviderTestBase();
+
+ protected:
+  // Methods to replace and restore CrosSettingsProvider for the specified path.
