Theories

More flexible and expressive assertions, combined with the ability to state assumptions clearly, lead to a new kind of statement of intent, which we call a "Theory". A test captures the intended behavior in one particular scenario. A theory captures some aspect of the intended behavior in possibly infinite numbers of potential scenarios. For example: @RunWith(Theories.class) public class UserTest

このテストコードはCoolだ！　“public void multiplyIsInverseOfDivideWithInlineDataPoints( @Between(first = -100, last = 100) int amount, @Between(first = -100, last = 100) int m ) { assumeThat(m, not(0));”
