add new test project to chromium

前言

想在自己的测试程序中，验证一些chromium的知识点。
先加一个自己的测试工程到chromium。
我先翻了一圈，找到chromium中有一个test_child_process的测试程序(exe)。
参考test_child_process，加入了自己的测试工程test_by_me.

实验

在chromium工程中建立自己工程的文件夹

Z:\chromium\src\base\test\test_by_me

放入自己的测试工程实现

// @file Z:\chromium\src\base\test\test_by_me\main.cpp
// @brief write some test code to study chromium project

/**
# cd /d Z:\chromium\src\
# gn --ide=vs args out\my_x86_d
# gn ls out\my_x86_d > d:\my_tmp\gn_list_target.log
# 新加的测试工程位置//base/test:test_by_me
# autoninja -C out\my_x86_d test_by_me
*/

#include <stdlib.h>
#include <stdio.h>

#define PROG_NAME "test_my_me"

int main(int argc, char** argv)
{
	printf(">> %s\n", PROG_NAME);
	printf("hello chromium\n");

	system("pause");
	return EXIT_SUCCESS;
}

修改Z:\chromium\src\base\test\BUILD.gn

为啥要修改这个编译配置? 因为我用vs2017搜索test_child_process.cc时(指定目录为Z:\chromium\src, 文件类型为*.gn; *.gyp; *.gni)，只有这个配置文件中有test_child_process.cc的配置。
在Z:\chromium\src\base\test\BUILD.gn尾部，加上test_by_me工程需要编译的实现文件。

executable("test_by_me") {
  sources = [
    "test_by_me/main.cpp",
  ]
}

产生工程

因为加入的测试工程是含在chromium解决方案里面的，需要完整的生成一次全部工程，在vs2017的chromium解决方案中的过滤器(src/base/test)中，才会包含test_by_me子工程.

# cd /d Z:\chromium\src\
# gn --ide=vs args out\my_x86_d
# gn ls out\my_x86_d > d:\my_tmp\gn_list_target.log

在d:\my_tmp\gn_list_target.log中找test_by_me子工程在chromium解决方案的过滤器中的位置

//base/test:test_by_me

编译子工程test_by_me

autoninja -C out\my_x86_d test_by_me

测试

这时，可以在vs2017中单步了，和用vs2017直接建立的工程一样.

备注

这个测试程序没有加入chromium代码库的任何特性，等后续实验再研究。
