* No longer runs e2e tests inside of Saucelabs because Chrome is also installed on Travis CI and we should keep Saucelabs available for other browsers that don't run inside of Dockers or Travis.
* Updates the Saucelabs Connect Tunnel to the most recent version that seems to include a major bug fix that should improve tunnel stability
* Changes the CircleCI resource class to the `xlarge` (similar as in angular/angular). This should speed up the Bazel builds due to more CPU threads and more RAM.
* No longer just runs the tests against the first browser of a test platform (travis, saucelabs, browserstack)
* Stability is more valuable than speed (runs sequentially on CI now)
* Update Saucelabs Connect
* Remove unused spec reporter
* Update from Edge 14 to Edge 17
* Fix pixel deviations in Edge 17
* Changes the wait timeout for Saucelabs and Browserstack from 2 minutes to 1 minute. This is possible now because if the timeout fails we still re-try to create a connection a second time.
* The logfile output should be printed if the tunnel connection can't be established. The logging is also useful to see the update message from Saucelabs for example.
* Updates the version of Sauce Connect to avoid potential flakes within the Saucelabs tunnels
* Fixes the invalid path for the `deploy-dashboard` script that runs in the deploy build stage
* Suppresses normal log messages from Saucelabs Conect. Error messages will still show up (In a follow-up PR the normal stdout will be printed together with the stdout on CI failures)
* No longer suppresses the whole Browserstack Tunnel execution. Stderr output will be printed if present. (In a follow-up stdout will be printed as well on CI failures)
* Switches to best-practice variable referencing in Bash
* Updates the saucelabs tunnel binaries to fix CI flakiness for unit tests and protractor.
From what we experience, older versions of Saucelabs tend to cause flakiness immediately (See `master` branch)
