Test Classes

Domain classes can be tested without having to insert data (with the exception of one method to run tests of insert, upsert and delete methods).

Basic Example

Using our example Domain class, PortalUsers, lets see what a test class would look like.

@IsTest
private class PortalUsersTest {
 
  // test that generating a new instance works
  // this will fail if the Custom Metadata records have not been setup
  @IsTest
  static void newInstanceTest() {
    IPortalUsers instanceByIds = PortalUsers.newInstance(
      new Set<Id>{ fflib_IDGenerator.generate(PortalUser__c.SObjectType) }
    );
    IPortalUsers instanceByRecords = PortalUsers.newInstance(new List<PortalUser__c>());
  }
  
 
  @IsTest
  static void insertAndUpdateOnRecords() {
    // Test insert, update and delete fires off triggers properly
    List<PortalUser__c> portalUsers = new List<PortalUser__c>{
      GenericTestFactory.createPortalUser(),
      GenericTestFactory.createPortalUser(),
      GenericTestFactory.createPortalUser()
    };
    insert portalUsers;
    update portalUsers;
    delete portalUsers;
  }
  
  @IsTest
  static void validateUserSsoTest() {
    // TODO: mock selector and/or service methods before running the domain class method
    List<PortalUser__c> portalUsers = new List<PortalUser__c>{
      GenericTestFactory.createPortalUser(),
      GenericTestFactory.createPortalUser(),
      GenericTestFactory.createPortalUser()
    };
 
    IPortalUsers portalUsersDomain = (IPortalUsers) Application.Domain.newInstance(portalUsers);
    portalUsersDomain.validateUserSso();
  }
}

NOTE: GenericTestFactory is a centralised place to create test data for mocking.
