• Mockito 1.x support (doesn’t work). Mockito 2 works but is beta
• ControllerLinkBuilder doesn’t work with Groovy
• Problems when using Elide (Elide is a Java library that lets you stand up a JSON API)
• Spock mocks cannot be created out of a test context (this interferes with injecting mocked beans into spring contexts) // code sample goes here, - mockito vs spock
• Native groovy mocks can’t be passed into constructors (casting issues)
