Hi Team,

I am facing issue when I am trying to mock googleads API calls for unit testing(using wiremock server which by using .withEndpoint option in AdwordsSession routes the Google ADS API call to localhost:8444 server) . I was able to narrow down the issue to mutate operation call in userlistOperation class. But I am unable to proceed further. I even checked the soap XML generated(below) with the SOAP XML that succeeded and I dont see any issues. Kindly help me in debugging the issue. Also please let me know if there is a mock capability available for UserList creation and updating users in them via Google API interface.

PFB the failure log messages:

Hello Warner,

Your SOAP request seems to be good. It is not possible to mock the UserList creation and updating users. Could you please share the complete logs and the scenario you are trying to achieve to investigate further?

Hi Sai Teja,

PFB the code I am using for mocking the userlist creation:

//Calling Program with endpoint set to localhost so that google ads API will not be called for testing

val session = new AdWordsSession.Builder()
  .withClientCustomerId("123-456-7891")
  .withDeveloperToken("AWEDEEDDDDDTREWQSDFGYTR")
  .withEndpoint("https://localhost:8444")
  .withUserAgent("foo")
  .withOAuth2Credential(credential).build()
GoogleUtils.createNewAudienceList("newlist", "new_email_list", session)

//Creates audience List

def createNewAudienceList(audienceListName: String, audienceListDescription: String,session:AdWordsSession ): Unit = {
 
    val userListService: AdwordsUserListServiceInterface = adWordsServices.get(session, classOf[AdwordsUserListServiceInterface])
    //Create a new UserList
    val userList = new CrmBasedUserList()
    userList.setDescription(audienceListDescription)

    if (audienceListDescription.toUpperCase().contains("EMAIL")) {
      val uploadKeyType = CustomerMatchUploadKeyType.CONTACT_INFO
      userList.setUploadKeyType(uploadKeyType)
      userList.setName(audienceListName+"_Email")
      userList.setMembershipLifeSpan(10000L)
    }
    else {
      val uploadKeyType = CustomerMatchUploadKeyType.MOBILE_ADVERTISING_ID
      userList.setUploadKeyType(uploadKeyType)
      userList.setName(audienceListName+"_Maid")
      userList.setAppId(appId)
      userList.setMembershipLifeSpan(540L)
    }

    //Upload the newly created userlist in GoogleAds page using mutate operation
    val operation = new UserListOperation()
    operation.setOperand(userList)
    operation.setOperator(Operator.ADD)
    val result = userListService.mutate(Array(operation))
}
   
//Wiremock Server to intercept localhost calls
System.setProperty("javax.net.ssl.trustStore", System.getProperty("trustStore"))
private val wireMockServer = new WireMockServer(wireMockConfig().port(8080).httpsPort(8444).keystorePath(System.getProperty("trustStore")))
WireMock.configureFor("localhost", 8080)
wireMockServer.start()

Hello Warner,

In your code snippet when making mutate call "val result = userListService.mutate(Array(operation))", the mutation will be performed at the Google Ads servers and the result will be fetched and stored in the result variable. Since, you are changing the end point the mutation call is not happening and assigning null to the result variable. This is throwing the NullPointerException at your end. Instead changing the end point, you could make use of our Test accounts for your testing purpose. The test accounts are designed for this purpose only and the Ads in your test account will never serve and no billing information is needed. Otherwise mocking the user lists in your local server is not possible.
