Question

最近我开始学习单元测试，我想用gtest测试我的程序。我用这个订单安装所有：

$ git clone https://github.com/google/googletest 
$ cd googletest 
$ cmake -DBUILD_SHARED_LIBS=ON . 
$ make 
$ cd googlemock 
$ sudo cp ./libgmock_main.so ./gtest/libgtest.so gtest/libgtest_main.so ./libgmock.so /usr/lib/ 
$ sudo ldconfig

现在编写代码：

#include "gtest/gtest.h"

class Add
{
  private:
     int element;
  public:
     Add():element(0){}
     ~Add(){}
     void setElement(int e){ element = e; }
     int getElement() { return element; }
     int adder(int e) { return element += e; }
};

class AddTest : public ::testing::Test
{
  protected:
       int abc(int a){
            return a;
        }

     virtual void SetUp(){
          add1.setElement(1);
          add2.setElement(20);
     }
     virtual void TearDown(){}

Add add1;
Add add2;
};

TEST_F(AddTest, getTest)
{
   EXPECT_EQ(1, add1.getElement());
   EXPECT_EQ(20, add2.getElement());
}

int main(int argc, char **argv)
{
   ::testing::InitGoogleTest(&argc, argv);
   return RUN_ALL_TESTS();
}

当我运行测试时结束我收到此错误：

但是当使用命令

时

g++ main.cpp -o test -lgtest -lpthread

每一个人都很好。如何修复它并在命令行中运行它？

如果您正在使用CLion，那么您可能有一个CMakeLists.txt文件，您应该添加规则以链接到库。为此，请将以下行添加到CMakeLists.txt

enable_testing()
find_package(GTest REQUIRED) # Find the google testing framework on your system
include_directories(${GTEST_INCLUDE_DIRS})
target_link_libraries(${PROJECT_NAME} ${GTEST_LIBRARIES}) # Replace ${PROJECT_NAME} with your target name
