线程安全测试
我目前使用谷歌的 gtest 来编写我的单元测试，但它看起来不能测试线程安全性（即从多个线程访问某些内容并确保其行为符合规范）。
你用什么来测试线程安全？我想要跨平台的东西，但是，它至少必须在 Windows 上运行。
谢谢你！
I currently use googles' gtest to write my unit tests, but it doesn't look like it can test thread-safety (that is, accessing something from multiple threads and ensuring it behaves according to spec).
What do you use to test thread safety? I'd like something cross-platform, but, it definitely has to work on Windows atleast.
Thank you!

如果多线程代码不能立即、明显地、被证明是正确的，那么它几乎肯定是错误的。如果是的话，您不需要测试它。
说真的：共享可变状态应该是极其本地化和罕见的，并且执行它的类应该是明显正确的。
您的线程通常应该通过安全原语（例如线程安全工作队列）进行交互。如果您的代码周围散布着大量数据结构，每个数据结构都有自己的锁定策略，那么您的代码几乎肯定包含死锁和竞争条件。大量的测试工作只能发现一些问题。
If multithreaded code isn't immediately, obviously, provably correct then it is almost certainly wrong. And if it is, you don't need to test it.
Seriously: shared mutable state should be extremely localised and rare, and the classes that do it should be demonstrably correct.
Your threads should normally interact via safe primitives (eg a thread-safe work queue). If you have lots of data structures scattered around your code each with its own locking strategy then your code almost certainly contains deadlocks and race conditions. A big testing effort will only find some of the problems.
