Scala Test-Driven Development

ScalaMock

ScalaMock was perhaps the first mocking framework which understood that Scala is a different language than Java. It played on the fact that Scala allows both functional and object-oriented code. Therefore, the mocking framework for Scala needs to be able to mock both these as aspects of a Scala class.

It is a native framework and it allows mocking of both functions and objects. Paul Butcher wrote Scala mock.

Advantages of ScalaMock

• Type safe
• Open source
• Support for Scala-specific features such as:
  • Operator methods
  • Method overloading
  • Pattern matching
  • Parameterized methods

• Compatible with both ScalaTest and Specs2

We need to mix MockFactory into our test suite for us to be able to use ScalaMock with ScalaTest, as per the following example:

import ...
