VDM для интеграционных тестов

Question

Я использовал VDM, чтобы использовать внешний ODATA-сервис.Работает хорошо.Теперь я пытаюсь использовать VDM для тестирования интеграции, чтобы протестировать созданный сервис ODATA с использованием модели CAP.

Я использовал restTemplate.exchange () в тесте интеграции для тестирования сервиса ODATA.Это работало хорошо.Теперь я решил пойти с SDK VDM подход.Файлы VDM были сгенерированы успешно.Но при попытке запустить интеграционные тесты происходит сбой с исключением

com.sap.cloud.sdk.cloudplatform.exception.ShouldNotHappenException: java.lang.NullPointerException: при попытке вызвать метод com.google.gson.JsonObject.get (java.lang.String) пустого объекта, загруженного из локальной переменной 'xsuaaServiceCredentials'

Я передаю локальный токен JWT, а также набор VCAP_SERVICES в переменной среды.

Answer 1

Обновленный ответ:

После вызова мы пришли к выводу, что метод не был корректно смоделирован во время выполнения теста.

Пожалуйста, добавьте следующие строки кода в свой интеграционный тест с аннотацией @Before:

final String publicKey = "...";
final Map<String,String> verificationkey = ImmutableMap.of("verificationkey", publicKey);
final JsonObject xsuaaServiceCredentials = new Gson().toJsonTree(verificationkey).getAsJsonObject();
Mockito.when(((ScpCfCloudPlatform) CloudPlatformAccessor.getCloudPlatform()).getXsuaaServiceCredentials(ArgumentMatchers.any(DecodedJWT.class))).thenReturn(xsuaaServiceCredentials);

Это обеспечит правильную проверку протестированного приложения предоставленного токена аутентификации с подготовленным открытым ключом.

Я отправил этот сценарий нашей команде разработчиков, чтобы рассмотреть исправление этого потенциального пробела в функции.

Устаревший ответ:

Некоторые открытые точки для анализа проблемы:

1. Используете ли вы Cloud SDK только для тестирования или также в бэкэнде приложения?

2. Имеется в виду подсказка; Я бы не использовал try-catch в тестовом коде.

3. Рекомендуется создавать выделенный ErpConfigContext для каждого теста. Также, пожалуйста, используйте RequestContextExecutor :

   import com.sap.cloud.sdk.cloudplatform.servlet.RequestContextExecutor;
   

   с

   @Test
   public void createBusinessService() {
     new RequestContextExecutor().execute(() -> {
