mockkConstructor

Builds a constructor mock. Old constructor mocks of same classes are cancelled before.

Once used, every constructor of the given class will start returning a singleton that can be mocked. Rather than building a new instance every time the constructor is called, MockK generates a singleton and always returns the same instance. This will apply to all constructors for a given class, there is no way to distinguish between them.

// ClassToTest.log will now use a mock instance

Builds a constructor mock and unmocks it after the block has been executed.
