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?
答案 0 :(得分:0)
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
