Class FlipFlop<T>

java.lang.Object

com.atlassian.utt.mock.FlipFlop<T>

All Implemented Interfaces:

org.mockito.stubbing.Answer<T>

public class FlipFlop<T>
extends Object
implements org.mockito.stubbing.Answer<T>

An answer that can flip back and forth between two other answers.

Although this class is public, that is really so that more advanced consumers may override isFlipped() to rely on some condition other than an explicit call to flip() to change the state. Most test authors should be able to stick with the factory method MoreAnswers.flipFlop(Answer, Answer).

Since:

v0.0.1

Constructor Detail

FlipFlop

protected FlipFlop(org.mockito.stubbing.Answer<?> answer0,
                   org.mockito.stubbing.Answer<?> answer1)

Creates a flip-flop that will switch back and forth between answer0 and answer1.

Parameters:

answer0 - the initial answer to give

answer1 - the answer to switch to when flipped

Method Detail

isFlipped

public boolean isFlipped()

Returns true if currently flipped (using answer1); false if still using answer0.

If you wish to use something other than explicit calls to flip() to control the switching behaviour, then you can override this method to check whatever that is.

Returns:

true if (using answer1; false if using answer0.

flip

public boolean flip()

Flips between answer0 and answer1.

Calling this again will switch back. Of course, if you override isFlipped() to check something else instead, then this method probably won't do anything useful for you anymore.

Returns:

as for isFlipped() (reporting the new state)
