假设我们有两个函数 complexFunction 和 helperFunction，其中 complexFunction 调用了 helperFunction。我们将编写测试 complexFunction 的单元测试，并在调用 helperFunction 的地方打桩。

// 复杂函数示例
int helperFunction(int x) {return x * 2;
}// 调用了 helperFunction 的复杂函数
int complexFunction(int a, int b) {if (a > 0) {for (int i = 0; i < a; ++i) {if (i % 2 == 0) {b += helperFunction(i);}}} else {b = -1;}return b;
}

现在，我们将编写一个单元测试来测试 complexFunction 并在调用 helperFunction 的地方打桩。

#include <gtest/gtest.h>
#include <gmock/gmock.h>// 导入要测试的函数
#include "complex_function.h" // 假设你的函数保存在 complex_function.h 文件中// 引入命名空间
using ::testing::Return;// 模拟 helperFunction 函数
class MockHelperFunction {
public:MOCK_METHOD(int, helperFunction, (int), (const));
};// 单元测试套件
class ComplexFunctionTest : public ::testing::Test {
protected:// 在每个测试用例运行之前调用void SetUp() override {// 可以在这里进行初始化操作}// 在每个测试用例运行之后调用void TearDown() override {// 可以在这里进行资源释放等操作}// 模拟的 helperFunctionMockHelperFunction mock_helper;
};// 测试用例：测试 complexFunction 函数
TEST_F(ComplexFunctionTest, TestComplexFunction) {// 准备测试数据int a = 3, b = 2;// 设置预期调用EXPECT_CALL(mock_helper, helperFunction(::testing::_)).Times(3).WillRepeatedly(Return(4)); // 模拟 helperFunction 返回值// 调用 complexFunction 函数int result = complexFunction(a, b);// 验证结果EXPECT_EQ(result, 14);
}// 运行所有测试
int main(int argc, char **argv) {// 初始化 Google 测试::testing::InitGoogleTest(&argc, argv);// 运行所有测试用例return RUN_ALL_TESTS();
}
