CMake file for integrated Visual Studio unit testi

Visual Studio 2017 has integrated C++ unit testing (native, google test, ctest, etc.). How can I create a CMakeLists.txt file that will create a project like this that will use the integrated IDE testing, for example using either google test or the native microsoft unit testing framework? All of Microsoft's examples unfortunately just create the project in Visual Studio, rather than starting from a CMake file.

Any help is appreciated, thanks!

Mikewho,

I setup a small example using Google Test project that works with integrated IDE testing.

Create an empty directory and save these two files:

CMakeLists.txt

cmake_minimum_required(VERSION 3.0)
project(test_me)

# GTest
enable_testing()
find_package(GTest REQUIRED)
include_directories(${GTEST_INCLUDE_DIRS})

# Unit Tests
# Add test cpp file
add_executable( runUnitTests tests.cpp)
# Link test executable against gtest & gtest_main
target_link_libraries(runUnitTests ${GTEST_BOTH_LIBRARIES})
add_test( runUnitTests runUnitTests )

tests.cpp

#include <gtest/gtest.h>

TEST(ABC, TEST1) {
  EXPECT_EQ(true, true);
}

The in a command prompt type

mkdir build
cd build
cmake .. "-DCMAKE_TOOLCHAIN_FILE=C:/dev/vcpkg/scripts/buildsystems/vcpkg.cmake"

Note: I had vcpkg install gtest

C:\dev\vcpkg>vcpkg.exe install gtest

Make sure you have this installed in Visual Studio 2017

In Tools > Options > Test Adapter for Google Test set the regex to .exe

Build the solution and press Run all in the Test Explorer

The first time it runs it will find the test case

I hope this helps?
