php-lsp-test
============

[](#php-lsp-test)

`php-lsp-test` is a lightweight test harness for Language Server Protocol (LSP) servers in PHP projects, built for reliable use with PHPUnit.

It is inspired by [`pytest-lsp`](https://github.com/openlawlibrary/pytest-lsp), but intentionally adapted to PHP and synchronous PHPUnit workflows instead of async pytest fixtures.

Goals
-----

[](#goals)

- Start and control real LSP server processes from tests
- Send and receive JSON-RPC messages over stdio
- Assert protocol behavior in unit, integration, and end-to-end scenarios
- Reproduce editor-like flows in a deterministic PHPUnit environment
- Surface actionable diagnostics when tests fail (stderr/stdout/log messages)

Installation
------------

[](#installation)

Add as a dev dependency:

```
composer require --dev t3ide/php-lsp-test
```

Quickstart (PHPUnit)
--------------------

[](#quickstart-phpunit)

Use `LanguageServerTestCase` to spin up and initialize a client quickly:
