"expect unqualified_id before" 是一个编程错误的提示信息。它通常表示代码中出现了语法错误,编译器无法识别某个标识符。在这种情况下,编译器期望在某个位置之前有一个有效的标识符。
解决这个问题的方法是检查代码中的语法错误,确保所有标识符都已正确定义和声明。通常,这种错误可以通过仔细检查代码和调试来找到和解决。

'<' token
This error message is typically seen when the compiler encounters a syntax error in the code. In this case, it means that there is an unexpected '<' character in the code, and the compiler doesn't know what to do with it.
The most common cause of this error is a missing semicolon at the end of a statement, which can cause the compiler to interpret the following line of code as a continuation of the previous line. Another common cause is a missing header file, which can cause the compiler to fail to recognize a particular function or data type.
To fix this error, carefully check the syntax of the code and make sure that all statements are properly terminated with semicolons. Also, make sure that all necessary header files are included in the code.
EXPECT_DEATH_IF_SUPPORTED
EXPECT_DEATH_IF_SUPPORTED是Google Test框架中的一个宏,用于测试代码中是否会导致程序的非正常终止(比如崩溃)。它的作用是在测试中断言某个代码块会导致程序的非正常终止,如果程序没有崩溃,则测试失败。
EXPECT_DEATH_IF_SUPPORTED的使用方式如下:
```
EXPECT_DEATH_IF_SUPPORTED(statement, regex);
```
其中,statement是要测试的代码块,regex是一个正则表达式,用于匹配程序崩溃时输出的错误信息。
当使用EXPECT_DEATH_IF_SUPPORTED进行测试时,如果程序崩溃了,并且错误信息与给定的正则表达式匹配,那么测试通过。否则,测试失败。
需要注意的是,EXPECT_DEATH_IF_SUPPORTED只在支持异常处理的系统上有效。在不支持异常处理的系统上,该宏会被忽略,测试也会通过。
