HippoMocks用于动态mock生成

准备工作

// In [ClassUnderTest]Test.cpp file.
#include <gtest/gtest.h>
#include <hippomocks.h>
#include "[ClassUnderTest]Test.h"
// Test Method definition.
TEST_F([ClassUnderTest]Test, [Feature]_[Scenario]_[ExpectedBehavior])
{
    MockRepository mockEngine;
    CollaboratorService* mock = mockEngine.InterfaceMock<CollaboratorService>();
    ...
}

设置期望:
一定不被调用

mockEngine.NeverCall(mock, CollaboratorService::methodName);
mockEngine.NeverCallOverload(mock, (return_type(CollaboratorService::*)(arg1_type, arg2_type, ...))&CollaboratorService::methodName);

设置期望:
不一定被调用

mockEngine.OnCall(mock, CollaboratorService::methodName);
mockEngine.OnCallOverload(mock, (return_type(CollaboratorService::*)(arg1_type, arg2_type, ...))&CollaboratorService::methodName);

设置期望:
不一定被调用, 但如果一旦被调, 那么关心输入参数

mockEngine.OnCall(mock, CollaboratorService::methodName).With(arg1, arg2, ...);
mockEngine.OnCallOverload(mock, (return_type(CollaboratorService::*)(arg1_type, arg2_type, ...))&CollaboratorService::methodName).With(arg1, arg2, ...);

设置期望:
一定被调用, 但不关心输入参数

mockEngine.ExpectCall(mock, CollaboratorService::methodName);
mockEngine.ExpectCallOverload(mock, (return_type(CollaboratorService::*)(arg1_type, arg2_type, ...))&CollaboratorService::methodName);

设置期望:
一定被调用, 并关心输入参数

mockEngine.ExpectCall(mock, CollaboratorService::methodName).With(arg1, arg2, ...);
mockEngine.ExpectCallOverload(mock, (return_type(CollaboratorService::*)(arg1_type, arg2_type, ...))&CollaboratorService::methodName).With(arg1, arg2, ...);

设置期望:
一定被调用, 但不关心被调用的次序

mockEngine.autoExpect = false;
mockEngine.ExpectCall(mock, CollaboratorService::methodName1);
mockEngine.ExpectCall(mock, CollaboratorService::methodName2);

设置期望:
一定被调用, 并关心被调用的次序

mockEngine.ExpectCall(mock, CollaboratorService::methodName1);
mockEngine.ExpectCall(mock, CollaboratorService::methodName2);

显式验证

mockEngine.VerifyAll();
