Identify the assumptions about the initial system state in the following tests for XTrack story 4:
public class IterationStoryTest { public void testDisplay() { assertTrue( displayIteration("1") ); assertFalse( displayIteration("2") ); } public void testUpdate() { login("bob","bobspassword"); assertTrue( UpdateIteration( "1", "10", "20041201", "20041215") ); assertFalse( UpdateIteration( "2", "non-numeric", "bad date", "bad date" ) ); } }
The display test assumes iteration 1 has been defined and iteration 2 has not. The update test also assumes iteration 1 has been defined.
Are these tests rerunnable without resetting the system?
Yes, because executing the tests has no effect on the truth of the assumptions.
