Manual Testing to Automation Testing: 7 Proven Steps to Boost Your QA Career

11. Step 8: Learn Data-Driven Testing

Manual testers frequently test the same functionality with different data.

For example:

Username	Password	Expected Result
valid user	valid password	Login successful
invalid user	valid password	Error
valid user	invalid password	Error
blank	blank	Validation message

Instead of creating separate automation scripts for every scenario, you can use test data.

Conceptually:

Test Data
   ↓
Automation Script
   ↓
Execute Multiple Combinations
   ↓
Verify Results

This can save significant execution time.

12. Step 9: Learn API Testing

Once you are comfortable with UI automation, start learning API testing.

You don’t need to become an API expert immediately.

Start with:

• GET
• POST
• PUT
• PATCH
• DELETE
• Status codes
• Headers
• Request body
• Response body
• Authentication
• Assertions

For example:

Send Login API Request
        ↓
Receive Response
        ↓
Verify Status Code
        ↓
Verify Response

This will make your QA profile stronger.

13. Step 10: Learn Git and GitHub

Automation code needs version control.

That’s why Git and GitHub are important.

Learn basic commands such as:

git clone
git add
git commit
git push
git pull

You don’t need to learn every Git command.

Initially, understand:

Create project → Make changes → Commit → Push to GitHub

Your GitHub profile can then become a portfolio showing your automation work.

14. Step 11: Learn CI/CD Basics

You don’t need to become a DevOps engineer.

But as an automation tester, you should understand the basic idea.

For example:

Developer pushes code
        ↓
CI/CD Pipeline starts
        ↓
Automation Tests Execute
        ↓
Test Results Generated
        ↓
Team Gets Feedback

Tools you can explore later include:

• GitHub Actions
• Jenkins
• GitLab CI/CD
• Azure DevOps

Start with one.
