Tests are run on GitHub Actions. The configuration for this is in :file:`.github/workflows`.

CI is set up with secrets for connecting to Vuforia. These variables include those from :file:`vuforia_secrets.env.example`.

To avoid hitting request quotas and to avoid conflicts when running multiple tests in parallel, we use multiple target databases.

CI builds use a different credentials file depending on the build configuration. Within a workflow, this avoids conflicts.

Create environment variable files for secrets:

$ mkdir -p ci_secrets
$ cp vuforia_secrets.env.example ci_secrets/vuforia_secrets_1.env
$ cp vuforia_secrets.env.example ci_secrets/vuforia_secrets_2.env
$ ...

Add Vuforia credentials for different target databases to the new files in the ci_secrets/ directory. Add at least as many credentials files as there are builds in the GitHub test matrix. All credentials files can share the same credentials for an inactive database.

Choose a passphrase for the secrets. In the GitHub repository > Settings > Secrets, add a secret with the name PASSPHRASE_FOR_VUFORIA_SECRETS and the chosen passphrase.

Add the encrypted secrets files to the repository:

$ tar cvf secrets.tar ci_secrets/
$ gpg --yes --batch --passphrase="${PASSPHRASE_FOR_VUFORIA_SECRETS}" --symmetric --cipher-algo AES256 secrets.tar
$ git add secrets.tar.gpg
$ git commit -m "Update secret archive"
$ git push
