/**
 * TESTS OVERVIEW
 *
 * To include utest's environment, just include "utests.h" in the test's source
 * code. In case it is the main source code for a cmocka test group (there is a
 * main() function), define _UTEST_MAIN_ before including this header.
 *
 * TESTS VARIABLES
 *
 * Checking macros use internal storage to store various variables necessary
 * during the checking. It is possible to access these variables using the
 * following macros:
 *
 * UTEST_LYCTX    - libyang context
 * UTEST_IN       - input handler
 * UTEST_OUT      - output handler
 *
 * All these variables are cleaned with test's teardown.
 *
 * TESTS SETUP
 *
 * CMocka's CMUnitTest list definition macros (cmoka_unit_test*()) are replaced
 * by UTEST macro with possibility to specify own setup and teardown functions:
 *
 * UTEST(test_func) - only implicit setup and teardown functions are used
 * UTEST(test_func, setup) - implicit teardown but own setup
 * UTEST(test_func, setup, teardown) - both setup and teardown are test-specific
 *
 * Note that the tests environment always provide (and need) internal setup and
 * teardown functions. In case the test-specific setup or teardown are used, they
 * are supposed to include UTEST_SETUP at the setup beginning and UTEST_TEARDOWN
 * at the teardown end.
 *
 * Libyang context is part of the prepared environment. To add a schema into the
 * context (despite it is in the test-specific setup or in test function itself),
 * use UTEST_ADD_MODULE macro.
 *
 * LOGGING
 *
 * There are 2 macros to check content of the log from the previously called
 * libyang function. CHECK_LOG macro test only the last error message and path
 * stored directly via logging callback. CHECK_LOG_CTX gets error message and
 * path from the libyang context (in case the function does not store the error
 * information into the libyang context, the message cannot be checked this way).
 * libyang is set to store multiple error information, so multiple couples of
 * error message and path can be provided to be checked (the first couple
 * corresponds to the latest error). The macro also cleanups the errors list, so
 * it is fine to check that there is no error after succeeding successful
 * function call.
