How to write an e2e Test for runtime

Note: Require install git-lfs

We use git-lfs (Install by official website) to manage baseline images for e2e tests, so it's necessary to install it, ignore if already installed.

1. Create a case page in the e2e/case directory

You can refer to e2e/case/animator-play.ts.

2. Configure your e2e test in e2e/config.ts

The threshold is color difference threshold (from 0 to 1). Less more precise.

3. Debug your test cases:

Launch the Case page:

npm run e2e:case

After successfully launching the case page, run:

git lfs pull

Pull image from github, then run

npm run e2e:debug

Open the Cypress client for debugging. Cypress will capture screenshots of your case pages. Review the screenshots in e2e/downloads folder, store them in the e2e/fixtures/originImage directory if there are no issues, then rerun the test cases. If the test cases pass, the debugging is complete.

4. Run the complete e2e tests:

npm run e2e

Note: The e2e testing framework for this project is Cypress. For detailed usage instructions, please refer to https://www.cypress.io/.
