9 | * \author Andrey Semashev | |

12 | * \brief This file contains tests for the unhandled_exception_count internal function. | |
13 | * | |
14 | * The unhandled_exception_count function is not for public use but its tests show | |
15 | * whether the library will be able to emit log records in contexts when exceptions are being thrown. | |
16 | * | |
17 | * This file only contains the very basic checks of functionality that can be portably achieved | |
18 | * through std::unhandled_exception. | |
