YYCCommonplace/testbench/shared/parse_template.hpp

/**
 * \file
 * This file is a template for Parse function testing.
 *
 * As you seen that there is 2 style Parse function locate in main namespace and Rust namespace respectively.
 * Both of them share the exactly same test data sheet.
 * So it is good idea to extract these common part and put them into a place, and include it in respectively testbench file.
 * That what this file does.
 *
 * Before including this template file, you must make sure that:
 * \li Have include <gtest/gtest.h>
 * \li Have include <yycc/prelude/rust.hpp>
 * \li Have define a macro named \c TEST_NS which indicate the testbench namespace passed to gtest.
 * \li Have define a macro with syntax <TT>TEST_SUCCESS(type_t, value, string_value, ...)</TT>.
 * This macro will be called for those success case. \c type_t is the generic type of Parse function.
 * \c value is the expected value after parse and \c string_value is the string value to be parsed.
 * Other arguments should be redirect to corresponding Parse function.
 * \li Have define a macro with syntax <TT>TEST_FAIL(type_t, string_value, ...)</TT>.
 * Opposite with \c TEST_SUCCESS, this macro is for those bad case testing.
 * All arguments have the same meaning with \c TEST_SUCCESS.
