一个google Test文件案例

1， 建立头文件calculator.h

代码语言：javascript复制

//functions.h
#ifndef _FUNCTIONS_H
#define _FUNCTIONS_H


int add(int a,int b);
int myMinus(int a,int b);
int multiply(int a,int b);
int divide(int a,int b);
#endif

2 建立被测文件calculator.cpp

代码语言：javascript复制

//calculator.cpp
#include "calculator.h"
int add(int a,int b){
        return a b;
}
int myMinus(int a,int b){
        return a-b;
}
int multiply(int a,int b){
        return a*b;
}
int divide(int a,int b){
        return a/b;
}

3 建立测试文件calculatorTest.cpp

代码语言：javascript复制

//calculatorTest.cpp
#include "gtest/gtest.h"
#include "calculator.h"


TEST(AddTest,AddTestCase){
        ASSERT_EQ(2,add(1,1));
}
TEST(MinusTest,MinusTestCase){
        ASSERT_EQ(10,myMinus(25,15));
}
TEST(MultiplyTest,MutilplyTestCase){
        ASSERT_EQ(12,multiply(3,4));
}
TEST(DivideTest,DivideTestCase){
        ASSERT_EQ(2,divide(7,3));
}

4 建立总测试文件TestAll.cpp

代码语言：javascript复制

#include "gtest/gtest.h"
#include <iostream>
using namespace std;


int main(int argc,char* argv[])
{
        testing::GTEST_FLAG(output) = "xml:"; //若要生成xml结果文件
        testing::InitGoogleTest(&argc,argv); //初始化
        RUN_ALL_TESTS();                     //跑单元测试
        return 0;
}

在GTestApp目录下新建lib目录，并复制libgtest.a到其中

代码语言：javascript复制

mkdir lib
cp /home/jerery/googletest-main/lib/*.a ./lib

编译

代码语言：javascript复制

g   calculator.h calculator.cpp calculatorTest.cpp TestAll.cpp -o test -lgtest -lgmock -lpthread -std=c  14

运行测试

代码语言：javascript复制

./test --gtest_output=xml
root@jerry-virtual-machine:/home/jerry/googletest-main/googletest/myworkspace/calculator# ./test --gtest_output=xml

[ RUN      ] DivideTest.DivideTestCase
[       OK ] DivideTest.DivideTestCase (0 ms)
[----------] 1 test from DivideTest (0 ms total)


[----------] Global test environment tear-down
[==========] 4 tests from 4 test suites ran. (0 ms total)
[  PASSED  ] 4 tests.

查看产生xml文件：test_detail.xml

代码语言：javascript复制

cat test_detail.xml
?xml version="1.0" encoding="UTF-8"?>
