Customize

You can customize the auto-generated data of the Test Data Factory

Extend TestDataFactory.DefaultValueProvider class

Customize the auto-generated data

Create a default value provider class by extending the virtual class TestDataFactory.DefaultValueProvider

Implement the methods get{Type}DefaultValue that you want to override (available methods are listed in the table below)

public class MyDefaultValueProvider extends TestDataFactory.DefaultValueProvider{

  public override String getEmailDefaultValue(Schema.DescribeSObjectResult sObjectDesc, Schema.DescribeFieldResult fieldDesc, Integer counter){
  	return 'mycustomtestemail'+counter.format()+'@gmail.com';
  }

}

Here is the list of supported datatypes and the method that defines the default value for each type and their default value

Salesforce Datatype Method Default value for the creation of a single sObject Default value for the creation of a list of sObject
Base64 getBase64DefaultValue Blob.valueOf(0) Blob.valueOf(recordIndex)
Checkbox getCheckboxDefaultValue False //
Currency getCurrencyDefaultValue 0 recordIndex
Date getDateDefaultValue Date.today() //
DateTime getDateTimeDefaultValue Datetime.now() //
Email getEmailDefaultValue '[email protected]' 'test'+recordIndex+'@example.com'
Geolocation getGeolocationDefaultValue Location.newInstance(0,0) //
Number getNumberDefaultValue 0 recordIndex
Percent getPercentDefaultValue 0 recordIndex
Phone getPhoneDefaultValue '01 23 45 67 89' //
Picklist getPicklistDefaultValue The default value of the picklist otherwise the first value //
MultiPicklist getMultiPicklistDefaultValue The default value of the multipicklist otherwise the first value //
Text getTextDefaultValue 'test0' 'test'+recordIndex
TextArea getTextAreaDefaultValue 'test0' 'test'+recordIndex
Time getTimeDefaultValue Time.newInstance(12, 0, 0, 0) //
URL getURLDefaultValue 'http://test0.com' 'http://test'+RecordIndex+'.com'

recordIndex : index number (starting from 0) of each record when creating a list of sObjects

// : same value

Define required fields and/or optional fields

  • You can force non-required field to behave as a required field (example if a field is part of a validation rule)
  • You can force a required field to behave as a non-required field (example if a field is required but get its value from a trigger)

In the example below the fields Firstname, Description and Email of the Contact are defined as required fields so the Test Data Factory will auto-generate default values for those fields each time a Contact is created

The field Lastname of the Contact is defined as optional so the Test Data Factory will not generate a default value for it

public class MyDefaultValueProvider extends TestDataFactory.DefaultValueProvider{     
  public override Set<String> defineSObjectRequiredFields(Schema.SObjectType sObjectType){
      if(sObjectType == Contact.SObjectType){
          return new Set<String>{
              'Firstname',
              'Description',
              'Email'
          };
      }
      return null;
  }
  public override Set<String> defineSObjectOptionalFields(Schema.SObjectType sObjectType){
      if(sObjectType == Contact.SObjectType){
          return new Set<String>{
              'Lastname'
          };
      }
      return null;
  }
}

Using your custom default value provider class

Apply it to the current transaction:

Set your default value provider class as the default one before using the Test Data Factory

TestDataFactory.defaultValueProvider = new MyDefaultValueProvider();

Apply it globally:

In the TestDataFactory class, change default value provider from the DefaultValueProvider to your custom default value provider class

/** Default value provider instance */
private static DefaultValueProvider dvPrvdr = new DefaultValueProvider();

Apply your custom default value provider like below

/** Default value provider instance */
private static DefaultValueProvider dvPrvdr = new MyDefaultValueProvider();

Implement TestDataFactory.IFieldDefaultValue interface

Create a class that implements TestDataFactory.IFieldDefaultValue

getValue method give access to the counter

In this example we will create 100 Accounts that will be used to create 100 Cases

public class AccountIdWrapper implements TestDataFactory.IFieldDefaultValue{
  private List<Account> AccountList = null;

  public AccountIdWrapper(List<Account> accountList){
  	this.accountList = accountList;
  }

  public Object getValue(Integer counter){
  	return accountList.get(counter).Id;
  }
}

Provide the instance of your field default value in the map override for the TestDataFactory.createSObjectList method

// creating 100 Accounts
List<Account> accountList = TestDataFactory.createSObjectList('Account', new Map<String,Object>{
  'Description' => 'test'
},true,100);

AccountIdWrapper accIdWrapped = new AccountIdWrapper(accountList);

// creating 100 Cases
List<Case> caseList = TestDataFactory.createSObjectList('Case',new Map<String,Object>{
  'AccountId' => accIdWrapped
  'Contact.Description' => 'Create the related Contact',
  'Contact.AccountId' => accIdWrapped
},true,100);
