public class MockEditingContext extends EOEditingContext
MockEditingContext is a subclass of EOEditingContext
that can be used for fast in-memory testing of business objects.
Unit tests for logic which use fetch specifications or save to an editing context can be relative slow because full roundtrips to a database are being performed. Testing the same logic with a MockEditingContext ensures that nothing is being saved to or read from a database resulting in shorter execution time of the unit test. Also, you don't risk invalidating the persistent data with broken test cases.
Assuming there is an EOCustomObject called Person with the
attributes name, age, nationality and
partner. nationality is of entity Country
for which there is a constant list of objects in the database. We want to write a test for the
static Person method createFromDescription(String, EOEditingContext).

jane.setName("Jane Doe");
jane.setNationalityRelationship(Country.withName("Canada", mockEditingContext()));

assertSame(jane, newPerson.partner());

assertNull(newPerson.partner());
