集成“谷歌测试”；和“增强程序选项”
我有一个程序，使用谷歌测试和增强程序选项库来解析选项。 问题是谷歌测试也有它自己的选项解析器，所以我需要在将选项提供给谷歌测试之前过滤掉。
例如，当我运行 hello 时，我使用如下
hello --option1=X --gtest_filter=Footest.*
--option1 是我在将 --gtest_filter 选项传递给 google 测试之前使用的选项。
当我运行以下代码时，出现异常，因为 --gtest_filter 不是我用于 boost 程序选项的选项。如何组合那些 boost 程序选项无法识别的选项来提供 gtest 的输入？
#include <boost/program_options.hpp>
namespace po = boost::program_options;
#include <iostream>
#include <fstream>
#include <iterator>
using namespace std;
#include <gtest/gtest.h>
int main(int argc, char **argv) {
// filter out the options so that only the google related options survive
try {
int opt;
string config_file;
po::options_description generic("Generic options");
generic.add_options()
("option1,o", "print version string")
;
...
}
catch(exception& e) // *****************
{
cout << e.what() << "\n";
return 1;
}
testing::InitGoogleTest(&argc, argv);
return RUN_ALL_TESTS();
}
I have a program that uses google test, and boost program options library for parsing options.
The problem is that google test also has it's own option parsers, so I need to filter out before giving the options to the google test.
For example, When I run hello I use as follows
hello --option1=X --gtest_filter=Footest.*
--option1 is the option that I use before passing the --gtest_filter option to the google test.
When I run the following code, I got exception as --gtest_filter is not the option that I use for boost program options. How can I combine those options that boost program options doesn't recognize to give gtest's input?
#include <boost/program_options.hpp>
namespace po = boost::program_options;
#include <iostream>
#include <fstream>
#include <iterator>
using namespace std;
#include <gtest/gtest.h>
int main(int argc, char **argv) {
// filter out the options so that only the google related options survive
try {
int opt;
string config_file;
po::options_description generic("Generic options");
generic.add_options()
("option1,o", "print version string")
;
...
}
catch(exception& e) // *****************
{
cout << e.what() << "\n";
return 1;
}
testing::InitGoogleTest(&argc, argv);
return RUN_ALL_TESTS();
}

InitGoogleTest将删除 Google Test 知道的选项并将其余部分保留在argv中。argc也会相应调整。只需将对InitGoogleTest的调用放在其他选项解析代码之前即可。InitGoogleTestwill remove the options Google Test knows about and leave the rest inargv.argcwill also be adjusted accordingly. Simply put the call toInitGoogleTestbefore other option-parsing code.我在此页面中找到了忽略未知选项的选项 - http://www.boost.org/doc/libs/1_45_0/doc/html/program_options/howto.html#id2075428
I found an option to ignore unknown options in this page - http://www.boost.org/doc/libs/1_45_0/doc/html/program_options/howto.html#id2075428
