获得所有boost测试套件/测试用例 [英] getting all boost test suites / test cases

问题描述

如标题所示，我想从测试应用程序获取所有测试套件或测试用例（名称），在控制台中或作为xml输出。
测试框架是boost测试库。

As the title says, I want to get all test suites or test cases (name) from a test application, ether in the console or as xml output. Test framework is the boost test library.

有没有选项来实现这个？我在文档中没有发现任何有用的东西。

Is there an option to achieve this? I did not found anything useful in the documentation.

推荐答案

这可以使用全局定位。假设您有一个显式或自动生成的包含 main 的翻译单元（cpp文件），当提供了某个命令行参数时，可以拦截测试执行。然后，您可以使用自定义的访问者遍历测试树，其中列出了所有可用的测试。这是一个小的工作示例，通过编译和链接文件创建测试运行程序 main_test.cpp ， a.cpp 和 b.cpp ：

This can be done without much intrusion using a global fixture. Assuming you have a translation unit (cpp file) that contains main explicitly or auto generated, you can intercept test execution when a certain command line argument is provided. Then you can traverse the test tree using a customized visitor, which lists all available tests. Here is a small working example, which creates a test runner by compiling and linking files main_test.cpp, a.cpp and b.cpp:

main_test.cpp b

#include <string>
#include <iostream>

// --- Boost Includes ---
#define BOOST_TEST_MODULE MyTestSuite
#define BOOST_TEST_DYN_LINK
#include <boost/test/unit_test.hpp>

using namespace boost::unit_test;

struct Visitor : test_tree_visitor
{
  size_t level = 0;

  void visit( test_case const& test )
  {
    std::string indentation( level, '.' );

    std::cout << indentation << test.p_name << std::endl;
  }

  bool test_suite_start( test_suite const& suite )
  {
    std::string indentation( level, '.' );
    level++;

    std::cout << indentation << "Suite: " << suite.p_name << std::endl;
    return true;
  }

  void test_suite_finish( test_suite const& suite )
  {
    level--;
  }
};

struct GlobalFixture
{
  GlobalFixture( )
  {
    int argc = framework::master_test_suite( ).argc;
    for ( int i = 0; i < argc; i++ )
    {
      std::string argument( framework::master_test_suite( ).argv[i] );

      if ( argument == "list" )
      {
        Visitor visitor;

        traverse_test_tree( framework::master_test_suite( ), visitor );

        exit( EXIT_SUCCESS );
      }
    }
  }

};

BOOST_GLOBAL_FIXTURE( GlobalFixture )

a.cpp

#include <boost/test/unit_test.hpp>

BOOST_AUTO_TEST_SUITE ( TestA )

BOOST_AUTO_TEST_CASE ( TestFoo )
{
  BOOST_CHECK(true);
}

BOOST_AUTO_TEST_CASE ( TestBar )
{
  BOOST_CHECK(true);
}

BOOST_AUTO_TEST_SUITE_END() // TestA

b.cpp

#include <boost/test/unit_test.hpp>

BOOST_AUTO_TEST_SUITE ( TestB )

BOOST_AUTO_TEST_CASE ( TestFoo )
{
  BOOST_CHECK(true);
}

BOOST_AUTO_TEST_CASE ( TestBar )
{
  BOOST_CHECK(true);
}

BOOST_AUTO_TEST_SUITE_END() // TestA

./somelib_testrunner1 
Running 4 test cases...

*** No errors detected

传递参数 c $ c>在上面定义的fixture中使用导致

Passing the argument list used in the fixture defined above results in

Suite: MyTestSuite
.Suite: TestA
..TestFoo
..TestBar
.Suite: TestB
..TestFoo
..TestBar
