What is the difference between mocking and spying when using Mockito?
... was not producing real partial mocks and it was confusing for some users. Read more about spying: here or in javadoc for spy(Object) method.

Otherwise, you're right: all the methods o...

Constructors in JavaScript objects
...a note about the cls.prototype part: "shared across instances" is only for reading the value (calling announce). If you set myClassInstance.announce to another value, it creates a new property in myClassInstance, so it only applies to that object, not other instances of the class. Assigning to MyCla...
