我曾使用 VDM 来使用外部 ODATA 服务。它运作良好。现在我正在尝试使用 VDM 进行集成测试，以便使用 CAP 模型测试创建的 ODATA 服务。

我在集成测试中使用 restTemplate.exchange() 来测试 ODATA 服务。它运作良好。现在我决定使用 SDK VDM 方法。VDM 文件已成功生成。但是在尝试运行集成测试时，它失败并出现异常

com.sap.cloud.sdk.cloudplatform.exception.ShouldNotHappenException: java.lang.NullPointerException: 尝试调用从局部变量加载的空对象的方法 com.google.gson.JsonObject.get(java.lang.String) 'xsuaaServiceCredentials'

我确实传递了本地 JWT 令牌和环境变量中设置的 VCAP_SERVICES。

更新的答案：

通话后，我们得出结论，在测试运行时没有正确模拟方法。

请将以下代码行添加到带有@Before注释的集成测试中：

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);

这将确保被测试的应用程序可以使用准备好的公钥正确验证提供的身份验证令牌。

我将此方案转发给我们的开发团队，以考虑解决这个潜在的功能差距。

弃用的回应：

推进问题分析的一些开放点：

  1. 您是仅将 Cloud SDK 用于测试还是在应用程序后端中使用？

  2. 暗示的意思；我会避免将 try-catch 放在测试代码中。

  3. 建议为每个测试用例实例化一个专用的ErpConfigContext 。也请使用RequestContextExecutor：

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

    和

    @Test
public void createBusinessService() {
  new RequestContextExecutor().execute(() -> {
    ...
    lsoCreateHelper.execute(new ErpConfigContext("localhorst"));
    ...
  });
}

这是否有效或给您任何其他信息？
