add tests #84
Description
besides installing the app, there are currently no continuous integration tests
it would be useful to have at least one integration test that
- prefills the values from the default
- checks them
- adds to submission
- downloads submission
panel has a CI test setup that we could probably adapt https://github.com/holoviz/panel/blob/master/.github/workflows/test.yaml
P.S. also bokeh has an extensive test suite, e.g. tests look like https://github.com/bokeh/bokeh/pull/10495/files
