1. Testing and Test Driven Development
Phase Test Preperation

2. Getting a Clearer Picture
Getting to a stage where we understand the problem more clearly
Event tables
Use case diagrams / descriptions
An early prototype of the proposed system

3. Visual Studio Configuration
Project bank web facing front end
Project bank locally hosted back end
The class library
A database file linked to both presentation layers

4. Two More Things
A class diagram
Test plans

5. The Class Diagram

6. The Test Plan Test Type Test Data Expected Result Actual Result
Extreme Min
Min -1
Min (Boundary)
Min +1
Max -1
Max (Boundary)
Max +1
Mid
Extreme Max
Invalid data type
Other tests

7. Test Driven Development
Testing is error prone and boring
In TDD
Create a test that fails (test plan my not always encourage this)
Run the test and see it fail
Fix the error in a simplistic way
See the test pass
Re-factor to implement the feature correctly
All about small steps
Builds confidence in the system
Builds confidence in the programmer
Programming Pathways

8. The Phase Test You may bring with you to the test
Your class diagram
Your test plan
A single A4 page of handwritten notes
(This will be inspected prior to the test start)
You will create on the day
Test framework
Class library
Test cases for
2 x properties of different data type
2 x parameters of different data type

9. For Example Properties Parameters in Valid CountyNo Int32
DateAdded DateTime
Parameters in Valid
PostCode
DateAdded

10. Some Examples
We will now work through some examples to get you started
