pytest plugin for end-to-end testing of language servers
Project description
pytest-lsp: End-to-end testing of language servers with pytest
pytest-lsp
is a pytest plugin for writing end-to-end tests for language servers.
It works by running the language server in a subprocess and communicating with it over stdio, just like a real language client.
This also means pytest-lsp
can be used to test language servers written in any language - not just Python.
pytest-lsp
relies on the pygls
library for its language server protocol implementation.
See the documentation for details on getting started.
