Module testing 

Scaffolds temporary projects and in-process daemons for integration testing against language servers.

Enable with the testing feature flag:

aether-lspd = { version = "...", features = ["testing"] }

Projects

Projects are TestWorkspaces, so they share its file, write, path, and path_string helpers and are cleaned up when dropped.

• cargo_project(name) – A Cargo project with Cargo.toml and src/main.rs.
• node_project(name) – A Node.js/TypeScript project with package.json, tsconfig.json, src/index.ts, and TypeScript 7 installed locally with npm install.
• file_uri(path) – The LSP file:// URI for a path.

Daemons

• TestDaemon – An in-process daemon with deterministic shutdown. Its socket accepts connections as soon as spawn returns. TestDaemon::builder overrides the request, diagnostics and settle timeouts.
• configure_fake_server – Points a language at the shared fake language server. The fake server holds diagnostics for files containing // hold-diagnostics until it receives a fake/releaseDiagnostics request, and reports itself as loading while the workspace root holds a .fake-loading file, until a fake/finishLoading request.

Example

use aether_lspd::testing::{cargo_project, file_uri};

let project = cargo_project("my-test");
project.write("src/lib.rs", "pub fn hello() -> &'static str { \"hi\" }");
let uri = file_uri(&project.path("src/lib.rs"));
