[SalesForce] the correct JSON to deserialize a map of sObjects

I'm trying to store a map of sObjects in a static resource. I want to be able to store default values for test setup methods. I was able to get it working with the following JSON in the static resource:

{ 
"Account" : "{\"attributes\":{\"type\":\"Account\"},\"BillingCity\" : \"testCity\"}",
"Opportunity" : "{\"attributes\":{\"type\":\"Opportunity\"},\"Name\" : \"testOpp\"}"
}

and here's the code:

String strJson = [SELECT body, name from StaticResource where Name =: myresource].body.toString();
mapJsonObjects = (Map<String, object>)JSON.deserializeUntyped(strJson);
Account objAccount = (Account) JSON.deserialize((String) mapJsonObjects.get('Account'),Sobject.Class);

The JSON I would actually like to have in the static resource is:

{
   "Account":{
      "attributes":{
         "type":"Account"
      },
      "BillingCity":"testCity"
   }
   ...
}

but there is no way to deserialize this into an sObject as far as I can tell.

You need to use the typed deserialize method as follows...

String jsondata = '{ "Account" : { "attributes":{"type":"Account"},"BillingCity" : "testCity"}, "Opportunity" : { "attributes":{"type":"Opportunity"},"Name" : "testOpp"}}';
Map<String, SObject> mapJsonObjects = (Map<String, SObject>)
    JSON.deserialize(jsondata, Map<String, SObject>.class);
Account objAccount = (Account) mapJsonObjects.get('Account');
System.debug('Account BillingCity is ' + objAccount.BillingCity);
Opportunity objOpportunity = (Opportunity) mapJsonObjects.get('Opportunity');
System.debug('Opportunity Name is ' + objOpportunity.Name);

The trick is using the .class property to get the class type of the typed Map.

Map<String, SObject>.class

Results in

DEBUG|Account BillingCity is testCity

DEBUG|Opportunity Name is testOpp

Try adding this instead of your last line of code:

String jsonstr = (String)JSON.serialize(parameters.get('SObject'));
SObject restoredAcme = (Account)JSON.deserialize(jsonstr, Account.class);

The problem with what you're currently trying to do is that you're essentially trying to cast a Map to an Account - which as you've seen, you cannot do.

As a workaround, you can serialize the Map to String and then deserialize that String to an Account.

As sfdcfox suggested in a comment, you can use json2apex to generate the necessary code from a JSON sample. The app is a little out of date in that test methods should now be in a different class, so I generated the code and separated out the test method:

UserAgreements Class

public class UserAgreements {
    public class DisplayUserInfo {
        public String company;
        public String fullNameOrEmail;
    }

    public List<UserAgreementList> userAgreementList;

    public class UserAgreementList {
        public String displayDate;
        public DisplayUserInfo displayUserInfo;
        public Boolean esign;
        public String agreementId;
        public String latestVersionId;
        public String name;
        public String status;
    }


    public static UserAgreements parse(String json) {
        return (UserAgreements) System.JSON.deserialize(json, UserAgreements.class);
    }   
}

UserAgreementsTest Class

@isTest
public class UserAgreementsTest {
    static testMethod void testParse() {
        String json = '{'+
        '  \"userAgreementList\": ['+
        '    {'+
        '      \"displayDate\": \"2015-04-02T09:32:23-07:00\",'+

        '      \"status\": \"RECALLED\"'+
        '    }'+
        '  ]'+
        '}';
        UserAgreements obj = UserAgreements.parse(json);
        System.assert(obj != null);
    }
}
