GitHub Actions Workflow Patterns

When to Use

Implement testing, matrix builds, artifact preparation or an explicitly authorized deployment workflow for an existing repository.

Inputs

Inspect the repository's actual scripts, lockfile, supported runtimes, required check names and release policy. Read resources/implementation-playbook.md and references/common-workflows.md before choosing job boundaries.

Test Workflow

This Node example assumes the target repository declares npm test and supports Node 22. Adapt the runtime and command to the actual project. The pinned action revisions are explicit review inputs; verify them before adopting or updating the template.
