### Matrix Testing with go-version-file fallback
You can combine go-version with go-version-file in a matrix strategy to test across latest supported Go versions, and the minimal version specified in `go.mod` of your project.
```yaml
jobs:
test:
runs-on: ubuntu-latest
strategy:
matrix:
go-version: ['stable', 'oldstable', ''] # empty string to fall back on go-version-file
steps:
- uses: actions/checkout@v6
- uses: actions/setup-go@v6
with:
go-version: ${{ matrix.go-version }}
go-version-file: "go.mod" # this one is only used when go-version is not specified.
- run: go test ./...
```
