Test workflow (django/django-localflavor)
The Test workflow from django/django-localflavor, explained and optimized by Latchkey.
- D
- CI health grade
- 53/100
- Health score
- 3
- Jobs per trigger
- 4
- Fixes in the optimized version
In short
- CI health: D (needs work)
- The optimized version below points runs-on at Latchkey managed runners and adds run de-duplication, caching, and job timeouts.
What it does
This is the Test workflow from the django/django-localflavor repository, a real project running GitHub Actions. It is shown here with attribution under its BSD-3-Clause license.
Below, Latchkey shows a faster, safer version produced by its optimization engine.

What changed
- Run on Latchkey managed runners with one line (
runs-on), which apply the fixes below automatically and self-heal transient failures. Each Linux x64 job moves to the Latchkey size matching its vCPU count,latchkey-smallfor a standard 2 vCPU runner; macOS, Windows and arm64 jobs stay as written. - Cancel superseded runs when a branch or PR gets a newer push.
- Cache dependency installs on the setup step so they are served from cache.
- Add a job timeout so a hung step cannot burn hours of runner time.
What Latchkey heals here
This workflow has steps that commonly fail on transient issues (network, registries, flaky browsers). On Latchkey managed runners they are detected, retried, and self-healed instead of failing your build:
- Dependency installs
This workflow runs 3 jobs (8 with the matrix expanded) per trigger. All of them run on a standard GitHub-hosted Linux x64 runner, which in a private repository bills $0.006 a minute against $0.0025 on latchkey-small, 58% lower; in a public repository like this one they are free. Estimate the monthly difference with your own run counts.
Actions used in this workflow
- actions/checkout

Frequently asked questions
What does the Test workflow (django/django-localflavor) workflow do?
This is the Test workflow from the django/django-localflavor repository, a real project running GitHub Actions. It is shown here with attribution under its BSD-3-Clause license.
What CI health grade does this workflow get?
This Python workflow grades D. Paste your own workflow into the Latchkey grader to see its grade and the exact fixes.
How can I improve this Python workflow?
Add run de-duplication, caching, and job timeouts. Latchkey applies these automatically on managed runners when you point runs-on at Latchkey.
