如何从googletest中的异常获取backtrace信息？

问题描述

我试图做一些半测试驱动的设计，偶尔当我实现一个新的功能，它会有一个异常。所有gtest告诉我是什么例外，并且不给我任何backtrace信息。

如果我运行gdb --args --gtest_catch_exceptions = 0，它将在测试时停止，但是没有任何backtrace信息。它简单地说：

  [RUN] TESTNAME.test_case 
 EXCEPTION：exception description [Inferior 1（process 30528）exited代码0377] 
（gdb）bt 
无堆栈。 
   
 
解决方案
 code> gdb命令在抛出异常之前设置特殊断点。当它被命中，你可以看到backtrace像往常一样通过命令 bt 。请参见。
 
I'm trying to do some semi test driven design, and occasionally when I implement a new feature, it will have an exception somewhere.  All gtest tells me is what the exception is, and does not give me any backtrace information.  

If I run gdb --args  --gtest_catch_exceptions=0, it will stop at the test with the exception but not have any backtrace information.  It simply states:
[ RUN      ] TESTNAME.test_case
EXCEPTION: exception description[Inferior 1 (process 30528) exited with code 0377]
(gdb) bt
No stack.
 解决方案 
Use catch throw gdb command to set special breakpoint before your exception is thrown. When it is hit you can see backtrace as usual by command bt. See https://sourceware.org/gdb/onlinedocs/gdb/Set-Catchpoints.html.
