Ubuntu uses Gtest Unit test framework

Ext.: http://ningning.today/2014/11/12/%E6%B5%8B%E8%AF%95%E5%BC%80%E5%8F%91/ubuntu%E4%BD%BF%E7%94%A8gtest%E5%8D%95 %e5%85%83%e6%b5%8b%e8%af%95%e6%a1%86%e6%9e%b6/

Recently contacted Gtest,google's Open source C + + unit Testing Framework. Tell me about the steps to use on Ubuntu.

Installing the Gtest Development package:

sudo apt-get install libgtest-dev

Note that this step is to install the source code to/usr/src/gtest, you need to build the makefile with CMake and then make the static library.

sudo apt-get install cmake #安装cmakecd /usr/src/gtestsudo cmake CMakeLists.txtsudo makesudo cp *.a/usr/lib/ #拷贝生成的库到/usr/lib/

Write a simple test code testgcd.cpp

123456789101112131415161718192021

//testgcd.cpp#include <gtest/gtest.h>intGCD (intAintb//Calculation greatest common divisor{return 0= = b? A:GCD (b, a% B); }test (Gcdtest, inttest) {expect_eq (1, GCD (2,5)); Expect_eq (2, GCD (2,5)); Expect_eq (2, GCD (2,4)); Expect_eq (3, GCD (6,9));}intMainintargcChar**ARGV) {testing::initgoogletest (&AMP;ARGC, argv);returnRun_all_tests ();}

Then compile with g++, and note the libraries to be linked (you can also build with CMake, which is just a simple example):

g++ testgcd.cpp -lgtest_main -lgtest -lpthread

Executed under

./a.out

Look at the results of the output:

123456789101112131415161718

The output is easier to read. For more documentation and use of Gtest, refer to the official manual.

Testing under Engineering

When the test project is more, the general separation of the header files and implementation files, and then can be built with CMake.

1234567891011121314151617181920212223242526272829

//!gcd.h#ifndef Gcd_h#define gcd_hintGCD (intAintb);#endif //!gcd.cpp#include "Gcd.h"intGCD (intAintb) {return 0= = b? A:GCD (b, a% B); }//!testgcd.cpp#include "Gcd.h"#include <gtest/gtest.h>TEST (Gcdtest, inttest) {expect_eq (1, GCD (2,5)); Expect_eq (2, GCD (2,5)); Expect_eq (2, GCD (2,4)); Expect_eq (3, GCD (6,9));}intMainintargcChar**ARGV) {testing::initgoogletest (&AMP;ARGC, argv);returnRun_all_tests ();}

Next Write a CMakeLists.txt: (Specific information refer to CMake's documentation)

123456

cmake_minimum_required 2.6) # Locate Gtest Find_package (Gtest REQUIRED) include_directories (${gtest_include_dirs}) libraryadd_executable (testgcd testgcd.cpp gcd.cpp) target_link_libraries${ Gtest_libraries} pthread)

Perform:

123	CMake CMakeLists.txtmake./testgcd

You can see the same execution results.
