In this tutorial we shall show users the usage of doNothing<\/code> method. This method is basically resides inside the Mockito framework and is not a part of the JUnit.<\/p>\n

1. Introduction<\/h2>\n

Many developers thought about the ways to test methods but do nothing about this. They might want to run the method only for the purpose of some other things that are related to that method. But directly there is no test required on that method itself.

\nUse doNothing()<\/code> for setting void methods to do nothing.<\/p>\n

Note:<\/b> Beware that void methods on mocks do nothing by default.<\/p>\n

There are rare situations when doNothing()<\/code> comes handy. Sometimes is used in void<\/code> return methods or to a method that does not have side effects, or is not related to the unit testing you are doing.<\/p>\n

This is how definition of the doNothing()<\/code> method looks like.<\/p>\n

public static Stubber doNothing()\n<\/pre>\n
2. Project Dependencies<\/h2>\n
There are common things while we need to run or test the doNothing()<\/code> example.
