This function is not called for browser tests. So you should call
translate::TranslateManager::SetIgnoreMissingKeyForTesting(true) from
chrome/browser/translate/translate_browsertest.cc.

   if (!g_translate_service) {
     TranslateService::Initialize();
+    translate::TranslateManager::SetIgnoreMissingKeyForTesting(true);
   } else {
     translate::TranslateDownloadManager::GetInstance()->ResetForTesting();
     g_translate_service->OnResourceRequestsAllowed();
