or (equivalent) ui5-test-runner --url http://localhost:8080/testsuite.qunit.html --browser-args --unsecure --browser-args -- --browser-args --disable-infobars

Implementation notes¶

When facing the error ERROR: Failed to set up Chrome r<version>!, you might consider defining the environment variable PUPPETEER_SKIP_DOWNLOAD=true, see the corresponding puppeteer issue.
To use with the puppeteer docker image, the runner must be configured to find the packages : --alternate-npm-path /home/pptruser/node_modules.
1️⃣ Screenshot feature is failing because of missing structuredClone API on Node.js 16. Since the problem is inside puppeteer (issue), the feature is turned off for this version.
2️⃣ firefox does not support scripting in puppeteer, see this issue.
