Я использовал следующие команды / шаги для установки пакета разработки gtest (google test) в ubuntu-16.04:
sudo apt-get install libgtest-dev
sudo apt-get install cmake # install cmake
cd /usr/src/gtest
sudo cmake CMakeLists.txt
sudo make
# copy or symlink libgtest.a and libgtest_main.a to your /usr/lib folder
sudo cp *.a /usr/lib
Записал CMakeLists.txt в папку моего проекта, содержимое которого:
cmake_minimum_required(VERSION 3.5.1)
# Locate GTest
find_package(GTest REQUIRED)
include_directories(${GTEST_INCLUDE_DIRS})
# Link runTests with what we want to test and the GTest and pthread library
add_executable(runTests test.cpp)
target_link_libraries(runTests ${GTEST_LIBRARIES} pthread)
ОБНОВЛЕНИЕ: самый короткий код для воспроизведения эксперимента: файл myFunc.cpp
int main(){
std::string input="JUMBO";
std::cout << myFunc(input)<< std::endl;
return 0;
}
std::string myFunc(std::string input){
std::string result="";
result= input
return result;
}
и файл test.cpp
#include "myFunc.cpp"
#include <gtest/gtest.h>
TEST(NewTest, checkEquals){
ASSERT_EQ("JUMBO", myFunc("JUMBO"));
}
int main(int argc, char **argv){
testing::InitGoogleTest(&argc, argv);
return RUN_ALL_TESTS();
}
Иерархия проекта выглядит следующим образом:

Примечание: Я могу запустить свою программу в командной строке, используя:g++ --std=c++11 myfunc.cpp -o main и может проверить его вручную !, но не может запустить мой модульный тест с помощью google test.
Я понял проблему, т. Е. При компиляции компилятор не может распознать std::string.Может кто-нибудь сказать мне, где и как включить флаг --std=c++17 при выполнении тестовых случаев с использованием gtest?любое предложение?
