Launched: GitHub Action for fast Streamlit app testing

[jcarroll]

Just wanted to share, we recently launched streamlit-app-action, a GitHub Action that makes it easier than ever to add automated tests to your app repository on GitHub using Streamlit AppTest.

The action will:

• Run a simple smoke test on each page of your app to ensure it loads successfully
• Run any custom tests you included in your repo
• Optionally perform linting with ruff

You can read more in our latest tutorial update: Automate your tests with CI - Streamlit Docs

Here’s a minimal example workflow file you could add to your app repo to get started:

# .github/workflows/streamlit-app.yml
name: Streamlit app

on:
  push:
    branches: ["main"]
  pull_request:
    branches: ["main"]

permissions:
  contents: read

jobs:
  app-tests:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-python@v5
        with:
          python-version: "3.11"
      - uses: streamlit/streamlit-app-action@v0.0.3
        with:
          app-path: streamlit_app.py
