Using Catch2 in Visual C++ 2015 - c++

Question

I'm trying to make a Unit Testing project using the Catch framework, but am faced with Link errors.
I've set up the project as follows:
Create a Native Unit Test project
Add Catch to the include directories
Add #include <catch.hpp> to stdafx.h
Write the following simple source file
unittest.cpp:
#include "stdafx.h"
namespace Catch2_Test
{
TEST_CASE("Y U no work")
{
REQUIRE(1);
}
}

Answer 1

For integrating Catch into Visual Studio
refer the ACCU article Integrating the Catch Test Framework into Visual Studio, by Malcolm Noyes
For using Catch2 in pre-compiled headers,
refer Catch2 issue 1061, where horenmar gave an example. The changes have been released as part of v2.1.0
In summary, the solution given is:
// stdafx.h
#pragma once
#include "targetver.h"
#include <stdio.h>
#include <tchar.h>
#define CATCH_CONFIG_ALL_PARTS
#include "catch.hpp"
// PCH-test.cpp:
#include "stdafx.h"
#undef TWOBLUECUBES_SINGLE_INCLUDE_CATCH_HPP_INCLUDED
#define CATCH_CONFIG_IMPL_ONLY
#define CATCH_CONFIG_MAIN
#include "catch.hpp"
// tests1.cpp:
#include "stdafx.h"
TEST_CASE("FooBarBaz") {
REQUIRE(1 == 2);
}

Answer 2

The problem was that I had cloned Catch2 from the master branch, while the VS integration worked on a branch off Catch.
