Description

Pyodide's test suite uses pytest-pyodide's spawn_web_server function to serve files for in-browser tests. This tight coupling between the Pyodide core and pytest-pyodide makes it difficult to evolve the APIs of pytest-pyodide without breaking Pyodide's test suite.

Proposed Solution

We should deprecate the use of spawn_web_server in Pyodide's core test suite and migrate to pytest-httpserver. This approach offers a cleaner, more standard way to serve files during testing.

All remaining instances of spawn_web_server in the Pyodide test suite should be replaced with pytest-httpserver to handle file serving. This will reduce coupling and align Pyodide's testing infrastructure with a more robust and purpose-built tool.
