Isolator Features > Your tests will be more maintainable > All fake behavior is "Forever" by default


When using Isolator, setting behavior of a method once, changes that method behavior for all calls against it. That means that if your production code changes and calls a method more than once, your tests won't break -  your tests are less brittle.
