//! Tests of [`rustls::KeyLogFile`] that require us to set environment variables.
//!
//!                                 vvvv
//! Every test you add to this file MUST execute through `serialized()`.
//!                                 ^^^^
//!
//! See https://github.com/rust-lang/rust/issues/90308; despite not being marked
//! `unsafe`, `env::var::set_var` is an unsafe function. These tests are separated
//! from the rest of the tests so that their use of `set_ver` is less likely to
//! affect them; as of the time these tests were moved to this file, Cargo will
//! compile each test suite file to a separate executable, so these will be run
//! in a completely separate process. This way, executing every test through
//! `serialized()` will cause them to be run one at a time.
//!
//! Note: If/when we add new constructors to `KeyLogFile` to allow constructing
//! one from a path directly (without using an environment variable), then those
//! tests SHOULD NOT go in this file.
//!
//! XXX: These tests don't actually test the functionality; they just ensure
//! the code coverage doesn't complain it isn't covered. TODO: Verify that the
//! file was created successfully, with the right permissions, etc., and that it
//! contains something like what we expect.
