5.1 Testing and encapsulation

1. Phase One objective-encapsulate the functions of the calculation into classes.

2. Design test Case: Use white box and black box test design technology, design test case for computing core.

The first phase of the goal-the ability to encapsulate the functions of the calculation, through the test program and API interface to test its simple addition function.

Phase II goal-test its simple subtraction functionality through test programs and API interfaces. And you can see code coverage.

Phase III goal-test support for various parameters through the test program and API interface. And you can see code coverage.

Phase IV goal-the processing of various error situations is accomplished through incremental modification of the improvement Program.
