Automated GUI testing

[HansG]

Hello,

Has somebody ever used a framework for automated GUI testing like Splinter (https://splinter.readthedocs.io/en/latest/) with Dash?

If so, any best practices?

Yes - I use selenium in the integration tests for Dash. Here are some examples:

• Integration tests for Dash’s front-end: https://github.com/plotly/dash-renderer/blob/8d4970c2a9865136369d0c20ec9203d2a7c0fc46/tests/test_render.py
• Integration tests for dash-auth: https://github.com/plotly/dash-auth/blob/b7567697b9e3460501156b2552efa1afad89d7a6/tests/test_integration.py
• Here’s a circle.yml file for running these tests on CircleCI: https://github.com/plotly/dash-auth/blob/b7567697b9e3460501156b2552efa1afad89d7a6/circle.yml and it’s associated tox file: https://github.com/plotly/dash-auth/blob/b7567697b9e3460501156b2552efa1afad89d7a6/tox.ini. These tests run across multiple versions of python
• In the utils.py function, there are some helpful utilities like wait_for: https://github.com/plotly/dash-auth/blob/b7567697b9e3460501156b2552efa1afad89d7a6/tests/utils.py#L39-L79, which can be used to wait for elements to render: https://github.com/plotly/dash-auth/blob/b7567697b9e3460501156b2552efa1afad89d7a6/tests/test_integration.py#L61

I hope that helps!
