//! 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.
