How to Delay a Stubbed Method Response With Mockito

Date: 2024-08-16

This article demonstrates three methods for introducing delays into stubbed methods using Mockito for unit testing. Thread.sleep() provides a simple, but less flexible, approach. Mockito's Answer interface offers more control over custom behavior, including delays. Finally, Awaitility provides a more robust solution for asynchronous testing, enabling flexible waiting conditions and reducing the risk of flaky tests. Choosing the right method depends on the specific testing needs and the complexity of the asynchronous behavior being simulated. Careful consideration of delay lengths is crucial for maintaining test stability.
