发送到应用程序的 CTRL-C 单元测试

I am developing an application handling CTRL-C. I am producing a signal handler to shut-down gracefully threads and other resources.

I want to test CTRL-C in different scenarios where my application might be. I know how to setup those for the process under test, but I need a way (in the code of the running test suite) to check whether that condition is reached or not to call exactly CTRL-C.

I work in Linux and I want to run my tests automatically with the help of CPPUNIT. In each of my CTRL-C tests I start the process and then I send CTRL-C using kill function having the PID of the process.

I am using shared memory; once the tested application reaches a condition of my interest or a point when I would like to send CTRL-C, I write a tag or a state into the shared memory. Aat the same time the test suite code running in a different process is continuosly polling the shared memory and once it reads the desired state it send CTRL-C/kill.

您认为这是一个好方法还是通常以更好/有效的方式完成？

首先测试接收到某些外部信号时的行为看起来不像单元测试，而是像功能测试。

此外，您执行此操作的方式听起来也太复杂，并且可能会强制执行某种同步并隐藏某些行为。

另一方面，对于此类测试，我确实没有更好的建议，这通常是由外部工具以一种不太受控制的方式完成的。
