3. ssh <USER.NAME>@cg-vm1.scilifelab.se
4. sudo -iu hiseq.clinical
5. ssh localhost
6. (optional) Find out which scout branch is currently deployed on cg-vm1: podman ps
7. Stop the service with current deployed branch: systemctl --user stop scout.target
8. Start the scout service with the branch to test: systemctl --user start scout@<this_branch>
9. Make sure the branch is deployed: systemctl --user status scout.target
10. After testing is done, repeat procedure at https://pax.scilifelab.se/, which will release the allocated resource (scout-stage) to be used for testing by other users.

Testing on hasta server (Clinical Genomics Stockholm)

Prepare for testing

1. ssh <USER.NAME>@hasta.scilifelab.se
2. Book your testing time using the Pax software. us; paxa -u <user> -s hasta -r scout-stage. You can also use the WSGI Pax app available at https://pax.scilifelab.se/.
3. (optional) Find out which scout branch is currently deployed on cg-vm1: conda activate S_scout; pip freeze | grep scout-browser
4. Deploy the branch to test: bash /home/proj/production/servers/resources/hasta.scilifelab.se/update-tool-stage.sh -e S_scout -t scout -b <this_branch>
5. Make sure the branch is deployed: us; scout --version
6. After testing is done, repeat the paxa procedure, which will release the allocated resource (scout-stage) to be used for testing by other users.
