…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 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
