rust/crates/rust-analyzer/tests/slow-tests/main.rs

//! The most high-level integrated tests for rust-analyzer.
//!
//! This tests run a full LSP event loop, spawn cargo and process stdlib from
//! sysroot. For this reason, the tests here are very slow, and should be
//! avoided unless absolutely necessary.
//!
//! In particular, it's fine *not* to test that client & server agree on
//! specific JSON shapes here -- there's little value in such tests, as we can't
//! be sure without a real client anyway.
