BKubicki Magento 2 Unit Tests Doubles

Overview

Library provides useful doubles of different kinds for unit testing of Magento 2.3+. Some of the doubles can be created using dedicated builders, which helps in configuring desired behavior of doubles. By using these doubles you can get rid of over-mocking in unit tests and time spent on writing unit should decrease. It can be achieved because all doubles inherits or implements replaced object or interface, so type consistency is preserved. Examples in here.
