What is Equivalence Class Partitioning (ECP or EP)?

Equivalence Class Partitioning is tests based on evaluating input or output conditions and separating them into two or more sets

- Reduce # of tests to achieve "reasonable" coverage

- Covers a large set of possible data

- 2 basic sets: Valid class and Invalid class sets

Equivalence classes are formed by a partition of a set made up of subsets whose union is the entire set.
For example, in the triangle program a test for an equilateral triangle
may include the inputs (6,6,6). Another test with numbers from the same
subset (such as 8,8,8) would likely not produce a different result from
the previous test. From a code implementation view, the data is handled
the same way 
so the second test case using data from the same equivalence class can be considered a redundant test case.
