chromium base_unittests 内容

测试输出

通过下面的方式运行，标准输出会存储到 NS_base_UT.log, 标准错误输出会输出到终端：

其实在PC 上，当执行某个test的时候，它会自动生成一个 base_unittests.log 在相同目录。

由上面的错误输出可用看出， 

1. unittest 会依赖于  logging_unittest.cc 来产生log 信息。通过 “No such file or directory” 可用猜测在这里会去创建文件。

2. shared_memory_android.cc(50): base::SharedMemory::Open， system_monitor_android.cc(10):base::SystemMonitor::IsBatteryPower() 这两个function Not implemented, 需要了解以下它是如何判断这两个function not implemented
