> fusefs tests. Absolutely impossible to do in C. I considered Rust, but went with C++ so they could live in base. They are too closely coupled to fusefs(5) to live out-of-tree.
Can anyone comment on why this is impossible in C?

> I don't think anybody has claimed this yet. But I _have_ made a similar claim, that some things can't be written in C. I'll elaborate on the project that started this thread: the fusefs test suite. When I designed the fusefs test suite, I based it around the priniciple of Mocking. Each test case has a client thread that does normal file system access, and a server thread that implements a fuse file server. But it isn't a full implementation of a fuse file server; it's just a shim around a mock object. For each test case, the file server's behavior is programmed with expectations. The mocking technique is so limited and awkward to use in C that almost nobody bothers. Just compare the documentation for CMockery (C) with Mockall (Rust). C++'s Googlemock is somewhere in between.
