代码单元测试工具：gmock

Mock，更确切地说应该是Mock Object。当我们在单元测试、模块的接口测试时，当这个模块需要依赖另外一个/几个类，而这时这些类还没有开发好，这时我们就可以定义Mock对象来模拟那些类的行为。

mock工具的其中一个非常重要的作用是指定函数的行为（模拟函数的行为）。可以对入参进行校验，对出参进行设定，还可以指定函数的返回值。

Google's framework for writing and using C++ mock classes on a variety of platforms (Linux, Mac OS X, Windows, Windows CE, Symbian, etc). Inspired by jMock, EasyMock, and Hamcrest, and designed with C++'s specifics in mind, it can help you derive better designs of your system and write better tests.

Google Mock:

provides a declarative syntax for defining mocks,

can easily define partial (hybrid) mocks, which are a cross of real and mock objects,

handles functions of arbitrary types and overloaded functions,

comes with a rich set of matchers for validating function arguments,

uses an intuitive syntax for controlling the behavior of a mock,

does automatic verification of expectations (no record-and-replay needed),

allows arbitrary (partial) ordering constraints on function calls to be expressed,

lets a user extend it by defining new matchers and actions.

does not use exceptions, and

is easy to learn and use.

Google Mock is not a testing framework itself. Instead, it needs a testing framework for writing tests. Google Mock works seamlessly with Google Test, but you can also use it with any C++ testing framework.

MockCpp手册（中文）

1. 代码 mock_test.cc

#include <gtest/gtest.h>
#include <gmock/gmock.h>using namespace testing;class A {
public:int set(int num) {value = num;return num;}int get() {return value;}int value;
};class MockA : public A {
public:MOCK_METHOD1(set, int(int num));MOCK_METHOD0(get, int());};TEST(Atest, getnum)
{MockA m_A;int a = 10;EXPECT_CALL(m_A, set(_)).WillRepeatedly(Return(a));int k = m_A.set(200);EXPECT_EQ(10, k);
}int main(int argc, char *argv[]) {::testing::InitGoogleTest(&argc, argv);return RUN_ALL_TESTS();
}

2. 编译

g++ mock_test.cc -lgtest -lgmock -lpthread -std=c++11

3. 测试执行

baoli@ubuntu:~/tools/gtest/mytest$ ./a.out
[==========] Running 1 test from 1 test suite.
[----------] Global test environment set-up.
[----------] 1 test from Atest
[ RUN      ] Atest.getnum
[       OK ] Atest.getnum (0 ms)
[----------] 1 test from Atest (0 ms total)[----------] Global test environment tear-down
[==========] 1 test from 1 test suite ran. (0 ms total)
[  PASSED  ] 1 test.

4. 说明

4.1 MOCK_METHOD

MOCK_METHOD1(set, int(int num)); //调用set方法，一个参数（int num），返回int型

MOCK_METHOD0(get, int()); //调用get方法，无参数，返回int型

4.2 EXPECT_CALL

This means EXPECT_CALL() should be read as expecting that a call will occur in the future, not

that a call has occurred. Why does Google Mock work like that? Well, specifying the expectation

beforehand allows Google Mock to report a violation as soon as it arises, when the context (stack

trace, etc) is still available. This makes debugging much easier
