thrilled by some of those hand-written mocks. We encourage you to use Google Mock as: * a _design_ tool, for it lets you experiment with your interface design early and often. More iterations lead to better designs! * a _testing_ tool to cut your tests' outbound dependencies and probe the interaction between your module and its collaborators. # Getting Started # Using Google Mock is easy! Inside your C++ source file, just #include `"gtest/gtest.h"` and `"gmock/gmock.h"`, and you are ready to go. # A Case for Mock Turtles # Let's look at an example. Suppose you are developing a graphics program that relies on a LOGO-like API for drawing. How would you test that it does the right thing? Well, you can run it and compare the screen with a golden screen snapshot, but let's admit it: tests like this are expensive to run and fragile (What if you just upgraded to a shiny new graphics card that has better anti-aliasing? Suddenly you have to update all your golden images.). It would be too painful if all your tests are like this. Fortunately, you learned about Dependency Injection and know the right thing to do: instead of having your application talk to the drawing API directly, wrap the API in an interface (say, `Turtle`) and code to that interface: ``` class Turtle { ... virtual ~Turtle() {} virtual void PenUp() = 0; virtual void PenDown() = 0; virtual void Forward(int distance) = 0; virtual void Turn(int degrees) = 0; virtual void GoTo(int x, int y) = 0; virtual int GetX() const = 0; virtual int GetY() const = 0; }; ``` (Note that the destructor of `Turtle` **must** be virtual, as is the case for **all** classes you intend to inherit from - otherwise the destructor of the derived class will not be called when you delete an object through a base pointer, and you'll get corrupted program states like memory leaks.) You can control whether the turtle's movement will leave a trace using `PenUp()` and `PenDown()`, and control its movement using `Forward()`, `Turn()`, and `GoTo()`. Finally, `GetX()` and `GetY()` tell you the current position of the turtle. Your program will normally use a real implementation of this interface. In tests, you can use a mock implementation instead. This allows you to easily check what drawing primitives your program is calling, with what arguments, and in which order. Tests written this way are much more robust (they won't break because your new machine does anti-aliasing differently), easier to read and maintain (the intent of a test is expressed in the code, not in some binary images), and run _much, much faster_. # Writing the Mock Class # If you are lucky, the mocks you need to use have already been implemented by some nice people. If, however, you find yourself in the position to write a mock class, relax - Google Mock turns this task into a fun game! (Well, almost.) ## How to Define It ## Using the `Turtle` interface as example, here are the simple steps you need to follow: 1. Derive a class `MockTurtle` from `Turtle`. 1. Take a _virtual_ function of `Turtle` (while it's possible to [mock non-virtual methods using templates](http://code.google.com/p/googlemock/wiki/V1_7_CookBook#Mocking_Nonvirtual_Methods), it's much more involved). Count how many arguments it has. 1. In the `public:` section of the child class, write `MOCK_METHODn();` (or `MOCK_CONST_METHODn();` if you are mocking a `const` method), where `n` is the number of the arguments; if you counted wrong, shame on you, and a compiler error will tell you so. 1. Now comes the fun part: you take the function signature, cut-and-paste the _function name_ as the _first_ argument to the macro, and leave what's left as the _second_ argument (in case you're curious, this is the _type of the function_). 1. Repeat until all virtual functions you want to mock are done. After the process, you should have something like: ``` #include "gmock/gmock.h" // Brings in Google Mock. class MockTurtle : public Turtle { public: ... MOCK_METHOD0(PenUp, void()); MOCK_METHOD0(PenDown, void()); MOCK_METHOD1(Forward, void(int distance)); MOCK_METHOD1(Turn, void(int degrees)); MOCK_METHOD2(GoTo, void(int x, int y)); MOCK_CONST_METHOD0(GetX, int()); MOCK_CONST_METHOD0(GetY, int()); }; ``` You don't need to define these mock methods somewhere else - the `MOCK_METHOD*` macros will generate the definitions for you. It's that simple! Once you get the hang of it, you can pump out mock classes faster than your source-control system can handle your check-ins.
