Test project не выполняет test case

Создал юнит-тест c помощью Boost Test.

main.cpp

#define BOOST_TEST_MODULE MyTest
#include <boost/test/unit_test.hpp>
BOOST_AUTO_TEST_CASE( MyTest )
{
    BOOST_ERROR( "Ouch..." );           
}
int main()
{
    return 0;
}

Создал CmakeFile.

cmake_minimum_required(VERSION 2.8)
project(Test)
# Enable testing for the project
enable_testing()
set(CMAKE_CXX_STANDARD 11)
set(Boost_USE_STATIC_LIBS        ON)
set(Boost_USE_MULTITHREADED      ON)

find_package(Boost REQUIRED COMPONENTS system filesystem unit_test_framework)
include_directories(${Boost_INCLUDE_DIRS})
add_executable (Test main.cpp)
target_link_libraries (Test
        ${Boost_LIBRARIES}
        )

if(UNIX)
    target_link_libraries(${PROJECT_NAME} -pthread)
endif(UNIX)
# declares a test with our executable
add_test(NAME MyTest COMMAND Test)
> cd $test_path
> mkdir build     
> cd build
> cmake  ..       
> cmake --build . 
> ctest 

Выдает:

Test project /home/ilya-/Tests/build
    Start 1: MyTest
1/1 Test #1: MyTest ...........................   Passed    0.00 sec
100% tests passed, 0 tests failed out of 1
Total Test time (real) =   0.00 sec

Почему нету ошибки?
