Using boost-test with SFML and cmake
« on: February 08, 2022, 04:43:59 pm »
I'm writing a simple game in C++ with use of SFML. I want to use boost tests, but when i try to i get undefined reference in every place i use SFML features (the game itself works fine, it's just the test that don't). Sample test:
#include <boost/test/unit_test.hpp>
#include "Sentry.h"

BOOST_AUTO_TEST_SUITE(BasicModelTestSuite)

BOOST_AUTO_TEST_CASE(testLamp_10BulbsWithPower10_ExpectedPower)
    {
        sf::Texture projectileTexture;
        sf::Texture sentryTexture;
        std::vector<std::shared_ptr<Sentry>> foes;
        sentryTexture.loadFromFile("../GameResources/sentry_image.png");
        projectileTexture.loadFromFile("../GameResources/projectile_animation.png");
        foes.push_back(std::make_shared<Sentry>(Sentry(&sentryTexture, sf::Vector2u(1,2), 0.2f, sf::Vector2f(140,200), projectileTexture, true)));
        foes.push_back(std::make_shared<Sentry>(Sentry(&sentryTexture, sf::Vector2u(1,2), 0.2f, sf::Vector2f(200,200), projectileTexture, false)));
        BOOST_REQUIRE_EQUAL(foes.size(), 2);
    }

BOOST_AUTO_TEST_SUITE_END()

And the test portion of cmakelist.txt:
Quote
find_package(Boost 1.65 COMPONENTS "unit_test_framework" REQUIRED)

include_directories(
        ${CMAKE_CURRENT_SOURCE_DIR}/include
        ${Boost_INCLUDE_DIRS}
)

set(SOURCE_TEST_FILES
        test/master.cpp test/master.cpp test/baseTest.cpp
        main.cpp src/Level.cpp include/Level.h src/Game.cpp include/Game.h src/Platform.cpp include/Platform.h src/Item.cpp include/Item.h src/Life.cpp include/Life.h src/Coin.cpp include/Coin.h src/Collider.cpp include/Collider.h src/Enemy.cpp include/Enemy.h src/MrStrawberry.cpp include/MrStrawberry.h src/Animation.cpp include/Animation.h src/MrBerry.cpp include/MrBerry.h src/Projectile.cpp include/Projectile.h src/Sentry.cpp include/Sentry.h)

add_executable(TestProject ${SOURCE_TEST_FILES})

target_include_directories(TestProject PUBLIC include)

target_link_libraries(TestProject
        ${Boost_UNIT_TEST_FRAMEWORK_LIBRARY})

enable_testing()

add_test(NAME Test COMMAND TestProject
        --report_level=detailed
        --log_level=all
        --color_output=yes)

add_custom_target(check ${CMAKE_COMMAND} -E env CTEST_OUTPUT_ON_FAILURE=1 BOOST_TEST_LOG_LEVEL=all
        ${CMAKE_CTEST_COMMAND} -C $<CONFIGURATION> --verbose
        WORKING_DIRECTORY ${CMAKE_BINARY_DIR})

I have no clue why it throws undefined reference to everything, like this:
Quote
/usr/bin/ld: /home/student/CLionProjects/oop21_ww2_14/BerryGame/src/Projectile.cpp:8: undefined reference to `sf::RectangleShape::setSize(sf::Vector2<float> const&)'
/usr/bin/ld: /home/student/CLionProjects/oop21_ww2_14/BerryGame/src/Projectile.cpp:9: undefined reference to `sf::Shape::setTexture(sf::Texture const*, bool)'

As your code to be tested depends on SFML, you also need to link your test project against SFML, otherwise it won't know what to do with these includes and symbols.

You're right, thank you.
