How to Use Codecov: Track Test Coverage with GitHub Actions in Your CI Pipeline (Step-by-Step Guide)

Welcome back to the channel! 🚀 In this video, we’ll dive deep into Codecov, a powerful tool for visualizing test coverage in your projects. You’ll learn:

1. What Codecov is and why it’s essential for modern software development.
2. How to integrate Codecov into your CI pipeline using GitHub Actions.
3. How to use the Codecov dashboard to monitor test coverage for your codebase and track it over time.

By the end of this tutorial, you’ll have a clear understanding of how to leverage Codecov to make data-driven decisions about your tests and improve your project’s quality.

What is Codecov?
Codecov is an industry-leading tool designed to help developers understand their test coverage. By integrating Codecov into your CI pipeline, you can monitor how much of your codebase is covered by tests, track changes over time, and ensure your code quality stays top-notch.

Here is the coverage.yaml file I created in the tutorial:

name: Test and upload coverage

on: [push, pull_request]

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-go@v5
        with:
          go-version: 'stable'
      - name: download dependencies
        run: go mod download
      - name: test and get coverage
        run: go test -race -coverprofile=coverage.txt -covermode=atomic ./...

      - name: upload coverage
        uses: codecov/codecov-action@v4
        with:
          token: ${{ secrets.CODECOV_TOKEN }}
