Pytest plugin for testing Pyodide and third-party applications that use Pyodide

Installation

pytest-pyodide requires Python 3.10+ and can be installed with

pip install pytest-pyodide

You would also one at least one of the following runtimes,

  • Chrome and chromedriver
  • Firefox and geckodriver
  • node v14+

Usage

  1. First you would need a compatible version of Pyodide. You can download the Pyodide build artifacts from releases with,

    wget https://github.com/pyodide/pyodide/releases/download/0.21.0a3/pyodide-build-0.21.0a3.tar.bz2
tar xjf pyodide-build-0.21.0a3.tar.bz2
mv pyodide dist/

  2. You can then use the provided fixtures (selenium, selenium_standalone) in tests,

    def test_a(selenium):
    selenium.run("assert 1+1 == 2")   # run Python with Pyodide

    which you can run with

    pytest --dist-dir=./dist/

  3. For convenience, the run_in_pyodide decorator is also provided. For instance the above example would be equivalent to,

    from pytest_pyodide.decorator import run_in_pyodide

@run_in_pyodide
def test_a(selenium):
    assert 1+1 == 2
