     *   Mockito.mockingDetails(mock).getStubbings()
     * 
* What is 'stubbing'? * Stubbing is your when(x).then(y) declaration, e.g. configuring the mock to behave in a specific way, * when specific method with specific arguments is invoked on a mock. * Typically stubbing is configuring mock to return X when method Y is invoked. *

* Why do you need to access stubbings of a mock? * In a normal workflow of creation clean tests, there is no need for this API. * However, it is useful for advanced users, edge cases or framework integrators. * For example, Mockito internally uses this API to report and detect unused stubbings * that should be removed from test. Unused stubbings are dead code that needs to be removed * (see {@link MockitoHint}). *

* Manipulating the collection (e.g. by removing, adding elements) is safe and has no effect on the mock. *

* This method throws meaningful exception when object wrapped by MockingDetails is not a mock. * * @since 2.2.3 */ Collection getStubbings(); /** * Returns printing-friendly list of the invocations that occurred with the mock object. * Additionally, this method prints stubbing information, including unused stubbings. * For more information about unused stubbing detection see {@link MockitoHint}. *

* You can use this method for debugging, * print the output of this method to the console to find out about all interactions with the mock. *

* Content that is printed is subject to change as we discover better ways of presenting important mock information. * Don't write code that depends on the output of this method. * If you need to know about interactions and stubbings, use {@link #getStubbings()} and {@link #getInvocations()}. *

* This method was moved from the deprecated and semi-hidden type {@link MockitoDebugger}. *

* This method throws meaningful exception when object wrapped by MockingDetails is not a mock. * * @since 2.2.6 */ String printInvocations(); }
