SWE 437 In Class Exercise # 7
TDD on the Triangle program


Names:

Instructions: Work with your neighbors in groups.

Let's consider the venerable Triangle program. (This problem has been used as a "interview quiz" many times.)

   /**
     * @param s1, s2, s3:  sides of a putative triangle
     * decide what type of triangle, if any
     */
Try Koskela's TDD approach by applying the same methods as he demonstrated in Chapter 2.

Preliminaries:



Now, let's turn to adding functionality with TDD.
  1. Write a test for the triangle method.


  2. Implement enough code to make the test pass.


  3. Refactor as needed.


  4. Lather. Rinse. Repeat.
