在 Visual Studio Code 中对本机 C++ 进行单元测试

Question

I've been using Visual Studio Code to develop a low-level C++ library on a Mac. It seems to integrate with the compiler toolchain quite gracefully. But as to Unit Testing, I'm totally lost. There are a myriad of frameworks out there, none of them having been established as a standard, the way JUnit has. Moreover, the Visual Studio Code Unit Test Explorer has been very scantily documented .

Which unit testing frameworks integrate well with the Code frontend? How should one set up a unit testing project? I'm using SCons but I can switch to another build system if necessary.

Answer 1

For CMake. This is minimal setup for Code.

CMakeLists.txt

cmake_minimum_required(VERSION 3.5.1)
set(CMAKE_CXX_STANDARD 11)

set(CMAKE_CXX_FLAGS_RELEASE "-O2")

add_library(example ./some-path/example.cpp)

project(tests)

set(Boost_USE_STATIC_LIBS ON)
set(Boost_USE_MULTITHREADED ON)
set(Boost_USE_STATIC_RUNTIME OFF)
find_package(Boost 1.55 REQUIRED COMPONENTS unit_test_framework)

add_executable(${PROJECT_NAME} ./tests/tests.cpp)
target_include_directories(${PROJECT_NAME} PRIVATE ${Boost_INCLUDE_DIRS})
target_link_libraries(${PROJECT_NAME} example ${Boost_LIBRARIES})

add_custom_command(TARGET ${PROJECT_NAME} POST_BUILD COMMAND ${PROJECT_NAME})

tasks.json

{
    // See https://go.microsoft.com/fwlink/?LinkId=733558
    // for the documentation about the tasks.json format
    "version": "2.0.0",
    "tasks": [
        {
            "taskName": "build",
            "type": "shell",
            "command": "cd build && make" // cd to your build directory
        }
    ]
}

Now I can SHIFT + CTRL + b to build my project and CMake will show me Boost.Tests (passed/failed) at the end of compiling output in built-in Code console.

Example output of Code's console:

> Executing task: cd build && make <

Terminal will be reused by tasks, press any key to close it.
