gtest 是一种类似与CppUnit的,用于单元测试的库，由google公司开发并开放，以下为一个使用案例：
/*
must link gtest and pthread
g++ -o t28-gtest test28-gtest.cpp test28-CBasicMath.cpp -lgtest -pthread
*/
#include <iostream>
#include <string>
#include <sstream>
#include <list>
#include <gtest/gtest.h>#include "test28-CBasicMath.hpp"using namespace std;class CBasicMathTest : public ::testing::Test {
//protected:
public:void SetUp() override {m_testObj = new CBasicMath();}void TearDown() override {delete m_testObj;}CBasicMath *m_testObj;
};TEST(Foo, Int) {EXPECT_EQ(123, 123) << "Foo Bar test";
}TEST_F(CBasicMathTest, Addition) {EXPECT_EQ(3+4, m_testObj->Addition(3,4) );EXPECT_EQ(0+0, m_testObj->Addition(0,0) ) << "Normal test";EXPECT_EQ(-1, m_testObj->Addition(-1,0) ) << "Negative value test";//ASSERT_EQ(1+0, m_testObj->Addition(-1,0) ) << "Assert test";
}TEST(Foo, Double) {EXPECT_EQ(12.3, 12.3) << "Foo Bar test";
}TEST_F(CBasicMathTest, Multiply) {EXPECT_EQ(3*4, m_testObj->Multiply(3,4) );EXPECT_EQ(0, m_testObj->Multiply(0,0) ) << "Normal test";EXPECT_EQ(0, m_testObj->Multiply(-1,0) ) << "Negative value test";
}int main(int argc, char* argv[])
{::testing::InitGoogleTest(&argc, argv);return RUN_ALL_TESTS();
}
