Boost.Test support

Adding Boost.Test to your project

Install and build Boost Testing Framework following these instructions.
Note that CLion supports Boost.Test versions 1.55 and later.
Create a folder for Boost tests under the project root. For example, let's call it Boost_tests.

Create a CMakeLists.txt file inside the Boost_tests folder: right-click it in the project tree and select New | CMakeLists.txt.

Customize the following lines and add them into your script:

set (Boost_USE_STATIC_LIBS OFF)
find_package (Boost REQUIRED COMPONENTS unit_test_framework)
include_directories (${Boost_INCLUDE_DIRS})

# 'Boost_Tests_run' is the target name
# 'test1.cpp tests2.cpp' are source files with tests
add_executable (Boost_Tests_run test1.cpp tests2.cpp)
target_link_libraries (Boost_Tests_run ${Boost_LIBRARIES})

You can also use a live template for boost_with_libs, then adjust the template code to mimic the snippet above.

In your root CMakeLists.txt script, add the add_subdirectory(Boost_tests) command to the end, then reload the project.
In your source files with tests, add the following lines:
```
#define BOOST_TEST_DYN_LINK
#define BOOST_TEST_MAIN  // in only one cpp file
#include <boost/test/unit_test.hpp>
```
note
If you have several .cpp files with tests, #define BOOST_TEST_MAIN should be placed only in one of them.

Boost.Test run/debug configuration

Although Boost.Test provides the main() entry for your test program, and you can run it as a regular application, we recommend using the dedicated Boost.Test run/debug configuration. It includes test-related settings and let you benefit from the built-in test runner, which is unavailable if you run tests as regular programs.

To create a Boost.Test configuration, go to Run | Edit Configurations, click and select Boost.Test from the list of templates.
Specify the test or suite to be included in the configuration, or provide a pattern for filtering test names. Auto-completion is available in the fields to help you quickly fill them up:
Set wildcards to specify test patterns, for example:
In other fields of the configuration settings, you can set environment variables and command-line arguments.
With Boost.Test version 1.62 or earlier, in case you get the Test framework quit unexpectedly message, set the following string in Program arguments:
```
--log_format=HRF --log_level=all
```
Save the configuration, and it's ready for Run or Debug.

note
Instead of editing a single configuration, you can modify the Boost.Test template itself. In this case, the settings you specify will apply as defaults to all new configurations of this type.
