As part of a project at work, I implemented a Read/Write lock class in C++. Before pushing my code to production, what sort of tests should I run on my class to be sure it will function correctly.
I’ve obviously performed some sanity tests on my class (making sure only one writer can access at a time, making sure releases and claims increment and decrement properly, etc.)
I’m looking for tests that will guarantee the stability of my class and to prevent edge cases. It seems testing multi-threaded code is much harder than standard code.
It is very difficult to test multi-threaded code, so you should supplement your tests with a detailed code review by colleagues experienced in writing multi-threaded applications.
