Summary

Jenkins CI is used by Web QA to run automated tests. The production instance is publicly accessible and can be found here. Details of the setup and administration are available on our internal Mana page. We also have a staging instance for adhoc jobs and experimentation. This is secured behind Mozilla VPN, and can be found here. Documentation for the staging instance is also available on Mana.

Known Issues

• None

Troubleshooting

Try enabling verbose PIP output to determine if installation of Python packages is causing issues.

PIP index is unavailable

We use the main PyPI (Python Package Index) for installing Python packages. If this experiences issues then we can enable use of PIP mirrors.

PIP installation is slow

If Python packages are slow to install you should check that PIP mirrors are not enabled. If not, it may be that the main PyPI mirror is slow to respond.
