Review on Mockito by Nicholas Erickson

I like that it supports refactorings with annotations, which makes my code more readable and maintainable than before. It is not easy to write custom matchers. You need to understand how to use them effectively and then you can do some really cool things with your test suite. The documentation of this library is quite poor. For example, there are no examples at all! Just read their official tutorial (which isn't very detailed). But you have to know what they mean by "Mockery". Otherwise, it's just too hard to get started using Mockito. We were solving our problem related to testing asynchronous operations in Spring Boot microservices.
