NUnit - Pairwise

### PairwiseAttribute (NUnit 2.5)

The PairwiseAttribute is used on a test to specify that NUnit should generate test cases in such a way that all possible pairs of values are used. This is a well-known approach for combatting the combinatorial explosion of test cases when more than two features (parameters) are involved.

Note: In the current Alpha release, this attribute is accepted but ignored and data items are combined usin the default combinatorial approach.
