Mocking and Stubbing in MXUnit

//stubbing
public void function testSavingPerson()
output=false hint=""{
//create the mock of your dao
var mockPersonDAO = mock("PersonDAO","typeSafe");
//tell the mock that when save is called with the cut to return void
mockPersonDAO.save(variables.Person).returns();
//add it to the cut
injectProperty(variables.person,'personDAO',mockPersonDAO);
//now call the method to save
variables.person.save(); //variables.person is your component under test (aka cut)
mockPersonDAO.verify().save(variables.Person); //now all we have to do is make sure save was called properly
}
//mocking
public void function testCheckingForUsernameExistanceDoesSomething()
output=false hint=""{
//create the mock of your dao
var mockPersonDAO = mock("PersonDAO","typeSafe");
//what we expect the method we are testing to return
var expected = "Username does not already exist";
//placeholder for actual
var actual = "";
//now we mock the behavior of the function, the known username foo returns false in this case
mockPersonDAO.checkIfUsernameExists("foo").returns(false);
//add it to the cut
injectProperty(variables.person,'personDAO',mockPersonDAO);
//now we setup the cut, in this case i'll call set username to foo, which
//is the same string we told the dao to return "false" for
variables.person.setUsername("foo");
//set actual to the result of the method we are testing
actual = variables.person.verifyUsername();
//compare the results
assertEquals(expected,actual,"Verify username with username that doesn't exist should return proper string");
