The Ultimate Guide to Git & GitHub for QA Engineers

Blog banner

As a QA Engineer, knowing Git (version control) and GitHub (remote repository hosting) is not optional anymore. Modern QA workflows – whether manual or automation – rely on Git for:

  • Collaborating with developers & other testers
  • Maintaining test automation frameworks
  • Tracking changes in test scripts, data, and documentation
  • Rolling back safely when bugs are introduced
Tip for QAs: Treat your automation scripts, test cases, and configuration files just like code. Version control ensures no work is lost and every change is traceable.

Git Basics Every QA Must Know

Command What it does / Example
git clone <repo-url> Download a remote repo locally. Example: git clone https://github.com/org/repo.git
git status Check which files are staged, unstaged, or untracked.
git add . Stage all changes for commit. Use carefully – better to stage specific files during QA review.
git commit -m "msg" Save changes locally with a meaningful message. Example: git commit -m "Added login test cases"
git push origin <branch> Upload commits to the remote repo.
git pull origin main Fetch + merge changes from remote into your local branch.

Branching & Collaboration for QA

Branches are critical for QA engineers when testing new features or fixes:

  • git checkout -b feature/test-automation → Create & switch to a new branch
  • git merge feature/test-automation → Merge your test branch into main after review
  • git fetch origin → Get the latest branches without merging
QA Use Case: Always create a new branch for test cases (e.g., qa/test-bug-123) so you don’t break the main automation framework.

Advanced Git for QA Engineers

Command QA Perspective
git stash Temporarily save uncommitted changes when switching branches. Useful if you need to test another bug fix quickly.
git rebase main Re-apply your changes on top of the latest main branch (clean history). Ideal when preparing test scripts for PR review.
git log --oneline --graph See a visual history of commits. Great for tracking bug fix merges.
git revert <commit-id> Undo a specific commit safely (without rewriting history). Essential when a test script introduces failures.
git reset --hard HEAD~1 Discard the last commit completely. Use cautiously!

GitHub for QA Engineers

GitHub is more than just storing code – QAs use it for:

  • Pull Requests (PRs) → Review test scripts before merging
  • Issues → Log and track bugs directly linked with commits
  • Actions → Automate CI/CD pipelines (run automation tests on each commit)
  • Code Reviews → Ensure test automation follows standards
QA Workflow Example: 1. Pull latest automation framework → Create new branch → Add test cases → Push branch → Raise PR → Team reviews & merges.

Hands-On Practice for QAs

  1. Clone any public repo and explore git status, git log, git diff.
  2. Create a branch qa/test-login, add a dummy test file, commit & push.
  3. Simulate a bug: Change a file, stash it, switch branch, then re-apply stash.
  4. Rebase your test branch with main and resolve conflicts.
  5. Undo changes using git revert and git reset – see the difference.
  6. Raise a PR on GitHub and request review from a teammate.

Conclusion

As a QA Engineer, mastering Git & GitHub is not just about coding – it’s about collaboration, traceability, and quality. Whether you’re writing automation frameworks or reviewing test scripts, these skills ensure you stay aligned with modern software development practices.

Difference Between Smoke, Sanity & Regression Testing (With Examples)

Image
In software testing, terms like Smoke Testing , Sanity Testing , and Regression Testing are often used interchangeably, but they serve different purposes. Let’s dive into each type of testing with definitions, examples, and a clear comparison. What is Smoke Testing? Smoke Testing is a high-level test to check whether the major functionalities of an application are working after a new build or deployment. It’s often called a “Build Verification Test (BVT)” . Whenever a new build is received, some basic functionality of the application is verified. Purpose: To validate the stability of a build before proceeding to detailed testing. Performed on every new build release. To catch issue early on new build release. Example: Check if the application launches. Check if user login works. Check if main navigation is functional. Think of it as a basic health check before deeper diagnosis. What is Sanity Testing? San...

How Selenium Works for Web Automation

Image
Selenium is one of the most popular tools for web automation testing. It allows testers and developers to automate browsers for testing purposes or other repetitive tasks. To understand how Selenium works, we need to dive into its architecture and key components. What Is Selenium? Selenium is an open-source framework that automates web browsers. It supports multiple programming languages, including Java, Python, C#, and JavaScript, to write test scripts. Selenium is widely used for functional testing and supports all major browsers like Chrome, Firefox, Safari, Edge, and Internet Explorer. Selenium Components Selenium is not just a single tool; it’s a suite of tools designed to cater to different automation needs. Here are the core components: Selenium Component Details Selenium WebDriver Overview: Directly interacts with browsers via drivers to automate web applications. It supports multiple programming...
