Challenge 1: Write a Workflow for a Go Project — Possible Solution
====================================================================

name: CI

on: [push]

jobs:
  build-and-test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-go@v5
        with:
          go-version: '1.22'
      - run: go test ./...

WHY THIS WORKS
--------------
- on: [push] matches the challenge's requirement to trigger "on push" —
  the same trigger syntax used in this chapter's own Node.js example,
  just without also including pull_request since the challenge only
  asked for a push trigger.
- actions/checkout@v4 is still the FIRST step, exactly as this
  chapter's tip box insists — regardless of which language a project
  uses, every job starts on an empty runner, so the repo's Go source
  files need to be checked out before go test could possibly find
  anything to run.
- actions/setup-go@v5 with go-version: '1.22' is the direct Go
  equivalent of this chapter's actions/setup-node example — the
  chapter's own marketplace table lists setup-go alongside setup-node
  and setup-python as the same category of action (installing a
  specific language runtime version), just swapped for the language
  this challenge specifies.
- run: go test ./... is a plain shell command, correctly placed under
  run: (not uses:) since it's a direct command execution, not invoking
  a reusable marketplace action — matching this chapter's run-vs-uses
  distinction. The ./... pattern is Go's own convention (already
  covered in the Go testing course material) for running tests across
  every package in the module, not just the root package.
- This entire workflow follows the exact same four-step shape as the
  chapter's Node.js example (checkout → setup runtime → install/build
  as needed → run tests) — Go's tooling doesn't require a separate
  "install dependencies" step the way npm install does, since go test
  handles fetching needed modules itself, which is why this version has
  one fewer step than the Node.js original.
