OPIK-194 Sanity end-to-end tests - UI tests

[AndreiCautisanu]

Details

Setup a class structure for each page in the project to be expanded upon in the future as we add more flows and checks. Will try and keep all interactions with the pages themselves isolated in the Page classes to keep tests compact and readable.

Added tests to check creation of Traces and Spans via SDK, everything seems to work, will add the rest and re-test for any flakiness.

@ferc you can try and run these yourselves if you checkout the project branch, have python and Opik installed locally and do

cd tests/end_to_end
export PYTHONPATH='.'
pip install -r test_requirements.txt
pytest -s application_sanity/test_sanity.py --browser chromium --base-url http://localhost:5173 --setup-show --headed

Otherwise you can find a successful run on Actions here: https://github.com/comet-ml/opik/actions/runs/11216925985

Next commits

• small refactors to tests now that they work
• add tests for tags/metadata/scores
• add tests for database
• add tests for experiments

Don't merge until I've added the above and established when and how to run them at first, will add everything else and do a clean-up shortly
