/// performing these actions. Implementation depends a lot on the environment application is running in and thus there are several custom implementations
/// supported by the Boost.Test

/// In addition here you find interfaces for memory leaks detection and reporting.

///   - TODO
///
/// You can use this routine to select which one of the predefined debugger configurations to use in which case you do not need to provide starter
/// routine (the one provided by Boost.Test will be used). You can also use this routine to select your own debugger by providing unique configuration
/// id and starter routine for this configuration.
///
