Modern C++ Programming with Test-Driven Development

5.6 Using Mock Tools

Mock tools such as Google Mock, CppUMock, or Hippo Mocks simplify your effort to define mocks and set up expectations. You’ll learn how to use Google Mock in this section.

Defining a Derivative

Let’s test-drive ​summaryDescription​ again. We’ll need to mock the HTTP methods ​get​ and ​initialize​ .

virtual ~Http() {}
virtual void initialize() = 0;
virtual std::string get(const std::string& url) const = 0;

The first step in using the mock support built into Google Mock is to create a derived class that declares mock methods. Google Mock allows us to define the HttpStub derivative succinctly.

class HttpStub: public Http {
public:
 MOCK_METHOD0(initialize, ...
