I have a trigger on Account that makes a call to an apex class:

trigger AccountAddressTrigger on Account (after insert) {

Id patientAccountRecordTypeId = [SELECT Id, RecordType.DeveloperName FROM RecordType WHERE RecordType.DeveloperName = 'Patient_Account'].Id;

      for(account a:trigger.new){
        if( trigger.isInsert &&
            a.PersonMailingStreet != null &&
            a.PersonMailingCity != null &&
            a.RecordTypeId == patientAccountRecordTypeId &&
            personAccountsGeoCoder.isFirstTime = false;
            personAccountsGeoCoder.updatePersonAccount(a.Id); //this is the apex class

the Apex class : personAccountsGeoCoder then makes a callout using Salesforce's maps API. I go over the response and then grab the latitude and longitude values from the response and put them into the account record and do a DML update.

public class personAccountsGeoCoder {
    public static Boolean isFirstTime = true;
    @future (callout=true)
    public static void updatePersonAccount(Id accountToUpdate) { 
    // Create and add an address.
    Account a = [SELECT Id, PersonMailingStreet, PersonMailingCity,PersonMailingState, PersonMailingPostalCode, PersonMailingCountry FROM Account WHERE Id =: accountToUpdate];
    string shippingAddress = a.PersonMailingStreet+ a.PersonMailingCity + a.PersonMailingState + a.PersonMailingPostalCode+ a.PersonMailingCountry;

    Map<string,object> options = new Map<String,Object> {
                'version' => '1', // Required. Version of the API endpoint. Must be '1'.
                'address' => shippingAddress
    // Call the Geocode() method with the address.
    Map<String, Object>response = maps.API.Geocode(options); //this is the web callout 
    System.debug('::response::' + response);
    // Log the resulting geographical coordinates and formatted address. 
    Map<String, Object> response2 = (Map<String, Object>) response.get('data');
    System.debug('::response2::' + response2);
    Map<String, Object> response3 = (Map<String, Object>) response2.get('position');
    System.debug('::response3::' + response3);
    Decimal lat = (Decimal) response3.get('lat');
    Decimal longi = (Decimal) response3.get('lng');
    a.BillingLatitude = lat;
    a.BillingLongitude = longi;
    update a;

This works in Salesforce, but Im having issues writing the test class. This is what I have so far

public class UpdateBillingCoordinatesTest {
    public static void service_call() {

        StaticResourceCalloutMock mock = new StaticResourceCalloutMock();
        mock.setHeader('Content-Type', 'application/json');
        Test.setMock(HttpCalloutMock.class, mock);
        Id patientAccountRecordTypeId = [SELECT Id, RecordType.DeveloperName FROM RecordType WHERE RecordType.DeveloperName = 'Patient_Account'].Id;
        Account testAccount = new Account(
            RecordTypeId = patientAccountRecordTypeId,
            LastName = 'Test Account',
            PersonMailingStreet = '123 Test Street',
            PersonMailingCity = 'Indianapolis',
            PersonMailingState = 'IN',
            PersonMailingPostalCode = '46201',
            PersonMailingCountry = 'United States'
        insert testAccount;
        Account assertAcc = [SELECT Id, BillingLatitude, BillingLongitude FROM Account WHERE LastName = 'Test Account' LIMIT 1];
        System.debug('assertAcc' + assertAcc.BillingLatitude);
        System.assertEquals(37.78977, testAccount.BillingLatitude);

I made a static resource via setup>static resources>new and just uploaded a file containing the Json as provided by Salesforce (Salesforce Json Example)

However I am still getting the error : 'Methods defined as TestMethod do not support Web service callouts'

Am I missing something here?

    In addition to the above, I recommend you read this Q&A answer as to why you should not use a future from a trigger.

  • Mind Phil's recommendation - the given call of updatePersonAccount is not even bulkified, i.e. starts a future for each single ID instead of a List. Nov 3, 2023 at 12:08
