🧭 SDET Roadmap for Beginners: How to Start a Career in Testing + Coding


Want a job in tech but don’t know where to start? 🤔
SDET (Software Development Engineer in Test) is a great role if you enjoy problem-solving, quality, and a mix of coding + testing.
Here’s a beginner-friendly roadmap to help you understand and get started! 💼💻
👨💻 What is an SDET?
An SDET (Software Development Engineer in Test) is someone who:
✅ Writes code to test software automatically
✅ Makes sure apps/websites are working perfectly
✅ Knows a bit of programming, testing, and tools used by developers
✅ Helps catch bugs before users face them 🐞
🧭 SDET Roadmap (Step-by-Step)
🔹 1. Learn a Programming Language
Start with one easy language. Most popular:
Java ☕
Python 🐍
JavaScript 🌐
Learn:
Basics (variables, loops, conditions)
OOP (Object-Oriented Programming)
🧠 Tip: Free tutorials on YouTube or platforms like Udemy, GeeksforGeeks, W3Schools, etc.
🔹 2. Understand Software Testing Basics
You need to know what testing is!
Learn about:
📦 What is a bug?
🧪 Types of testing (manual, automation)
🔄 Software development life cycle (SDLC)
🔹 3. Try Manual Testing First 📝
Before you automate, try testing software manually.
You’ll learn:
Writing test cases
Finding and reporting bugs
Tools like Jira for bug tracking
🔹 4. Move to Automation Testing 🤖
Now, start writing code that tests automatically!
Learn:
🧪 Selenium – to test web apps
🧪 Postman – to test APIs
🧪 JUnit/TestNG – to run test scripts
🔹 5. Build a Testing Framework 🛠️
Once you’re confident, build your own test framework:
Use Page Object Model (POM)
Add logging & reports
Make it reusable
🔹 6. Learn Tools Developers Use 🧰
To work like a pro SDET, learn:
Git (track code changes)
Jenkins/GitHub Actions (run tests automatically)
SQL (to test data from databases)
🔹 7. Optional: Explore More!
Once you’re ready, try:
🚀 Performance Testing (JMeter)
🔒 Security Testing (OWASP ZAP)
