The server used for testing on localhost has less optimizations (e.g. serves uncompressed files), so we need to wait longer the ServiceWorker to be loaded and registered to allow Lighthouse to reliably detect it, especially on slower environments (e.g. CI).

Encryption
Based on https://github.com/circleci/encrypted-files
In the CircleCI web UI, we have a secret variable called KEY
https://circleci.com/gh/angular/angular/edit#env-vars
which is only exposed to non-fork builds
(see "Pass secrets to builds from forked pull requests" under
https://circleci.com/gh/angular/angular/edit#advanced-settings)
We use this as a symmetric AES encryption key to encrypt tokens like a GitHub token that enables publishing snapshots.
To create the github_token file, we take this approach:
- Find the angular-builds:token in http://valentine
- Go inside the CircleCI default docker image so you use the same version of openssl as we will at runtime:
docker run --rm -it circleci/node:10.12 - echo "https://[token]:@github.com" > credentials
- openssl aes-256-cbc -e -in credentials -out .circleci/github_token -k $KEY
- If needed, base64-encode the result so you can copy-paste it out of docker:
base64 github_token
