I like that it allows me to write code without having any dependencies, which makes my life easier when writing test cases with other frameworks or libraries (like JUnit).
It's also easy enough if you want just some basic stubbing of methods/properties - but there is no way out from this dependency hell once we start using more advanced features such as spying etc., so be sure about what exactly do need before jumping into testing your project! We are solving problems related to our mobile application by mocking its API calls made through third party SDKs used during development phase.
