Object Mocking is used to keep dependencies out of your unit test. Sometimes you’ll have a test like ‘SelectPerson’ which will select a person from the database and return a Person object.
To do this, you would normally need a dependency on the database, however with object mocking you can simulate the interaction with the database with a mock framework, so it might return a dataset which looks like one returned from the database and you can then test your code to ensure that it handles translating a dataset to a person object, rather than using it to test that a connection to the database exists.
