/* FDO_DBUS_CONTEXT macro will be replaced by KWalletDBusContextDummy during
 * preprocessing if FDO_ENABLE_DUMMY_MESSAGE_CONNECTION was defined,
 * otherwise we get QDBusContext.
 *
 * This is used for mocking QDBusContext in autotests.
 *
 * QDBusContext's connection() and message() member functions can't be called
 * without a real connection context (this cause segfault).
 * So we need to use KWalletDBusContextDummy in case some DBus-related
 * member functions may call connection()/message().
 *
 * This header defines FDO_DBUS_CONTEXT macro that should be used instead of
 * QDBusContext in all DBus-related which we want to use in autotests.
