  1. Systems Life Cycle: Testing

  2. Testing • A test plan will be included in the design phase to explain exactly how the new system will be tested and the expected outcomes for each test. • Testing is important because computer software is usually very complex. Any mistakes made by the designers or programmer can have a dramatic effect depending on what the software is used for. • Testing helps to ensure that the system always acts as expected.

  3. Test data • Usually software is tested with three distinct types of data. • Typical data – this is normal data the system should be working with. • Extreme data – this is data at the boundary between typical data and invalid data. • Invalid data (sometimes known as erroneous data) – this is data that should cause the system to tell the user that there is a problem with data entered into the system.

  4. Data for testing in a school database – Pupil’s date of birth For each of the examples of data decide why – in our school’s database – it should be accepted or rejected.
