Who This Roadmap Is For

This roadmap is designed for:

  • Complete beginners entering Automation Testing.
  • Manual Testers transitioning into Automation.
  • Freshers preparing for SDET interviews.
  • Study Time: Approximately 2 hours per day
  • Frequency: 6 days per week
  • Learners with prior Java or Manual Testing experience can skip directly to the appropriate month using the guide at the end of this article.

A Practical Expectation

There are no shortcuts to becoming an SDET.

Six months of consistent practice is far more valuable than rushing through tutorials in a few weeks. Every month in this roadmap ends with something you build, not something you simply read.

Month 1 — Testing Foundations

Why Start Here?

Automation is effective only when you understand software testing fundamentals. Every SDET interview begins with Manual Testing concepts.

Week Focus Area Tutorials
Week 1 Testing Basics, Manual vs Automation Manual & Automation Testing
Week 2 Testing Types, Defect Management Functional Testing TypesDefect & Bug Management
Week 3 SDLC, STLC, Agile & Documentation SDLC & STLCAgile Scrum for Testers
Week 4 Test Design Techniques & Jira Test Design TechniquesComplete Jira Guide

Month 1 Milestone

  • Create a complete Test Plan.
  • Write 20 real test cases.
  • Report at least 5 defects using a free Jira project.

Month 2 — Core Java

Why Java?

Java forms the foundation for Selenium, TestNG, REST Assured, and Automation Frameworks. Strong Java skills make framework development and interview discussions significantly easier.

Week Focus Area Tutorials
Week 1 Java Basics, JVM & Control Flow Java BasicsJVM Fundamentals
Week 2 Object-Oriented Programming Java OOP & Keywords
Week 3 Interfaces & Collections Interfaces in JavaCollections Framework
Week 4 Strings & Exception Handling Strings, Wrappers & Exceptions

Month 2 Milestone

Complete at least 20 Java Coding Programs from memory rather than copying solutions.

Month 3 — Selenium Fundamentals

Why Selenium?

Selenium remains one of the most requested automation skills in SDET job descriptions.

Week Focus Area Tutorials
Week 1 Selenium Architecture & First Script Selenium WebDriver Fundamentals
Week 2 Locators & XPath ⭐ Selenium Locators & XPath
Week 3 Waits & Synchronization ⭐ Selenium Waits & Synchronization
Week 4 Forms, Alerts, Frames & Windows Form ElementsAlerts, Frames & Windows

Areas Worth Extra Practice

Spend additional time mastering:

These topics appear in nearly every Selenium interview.

Month 3 Milestone

Automate an end-to-end e-commerce workflow:

  • Login
  • Product Search
  • Add to Cart
  • Checkout Flow

Month 4 — TestNG & Automation Framework

Why Framework Development?

Writing Selenium scripts is only the beginning. Building a maintainable automation framework is what interviewers expect from SDETs.

Week Focus Area Tutorials
Week 1 TestNG Essentials Annotations, Assertions & DataProvider
Week 2 Page Object Model Frameworks & Page Object Model
Week 3 Data-Driven Testing & Maven Apache POIMaven & CI/CD
Week 4 Build an End-to-End Framework E-Commerce Selenium Framework

Month 4 Milestone

Publish your own Automation Framework on GitHub featuring:

  • Page Object Model
  • TestNG
  • Configuration Management
  • Data-Driven Testing
  • Extent Reports

This becomes your primary portfolio project.

Month 5 — API Testing

Why API Testing?

Modern SDET roles involve extensive API automation because APIs are faster, more reliable, and easier to automate than UI workflows.

Week Focus Area Tutorials
Week 1 API Fundamentals, HTTP & Status Codes API FundamentalsHTTP Methods
Week 2 Postman Complete API Testing Guide
Week 3 REST Assured REST Assured Setup & Syntax
Week 4 Authentication, Schema Validation & API Framework Complete REST Assured Guide

Month 5 Milestone

Build and publish an API Automation Framework using a public demo API such as RESTful Booker or FakeStore.

Upload the project to GitHub.


Month 6 — CI/CD, SQL & Interview Preparation

Why Finish Here?

The final month connects all previous skills into a production-ready automation workflow.

Week Focus Area Tutorials
Week 1 Git & Jenkins Complete Git GuideComplete Jenkins Guide
Week 2 SQL for Testers Complete SQL Guide
Week 3 Java Coding Practice ⭐ Java Coding Programs Guide
Week 4 Mock Interviews & Job Applications Complete SDET Interview Guide

Month 6 Milestone

  • Execute your Automation Framework from Jenkins.
  • Configure automatic execution on every Git commit.
  • Apply for at least 20 SDET or Automation Testing roles.

Six-Month Learning Snapshot

Month Skills Learned Portfolio Outcome
Month 1 Manual Testing Fundamentals Test Plan & 20 Test Cases
Month 2 Core Java 20 Java Coding Programs
Month 3 Selenium Automation End-to-End Selenium Project
Month 4 TestNG & Framework Design Automation Framework on GitHub
Month 5 API Testing REST Assured API Framework
Month 6 Git, Jenkins, SQL & Interviews Jenkins Pipeline & Job Applications

Four Honest Warnings

1. Don't Skip Manual Testing

Automation without testing knowledge leads to poor automation design and weak interview performance.

2. Don't Skip Java

Weak Java skills eventually become the biggest obstacle when building frameworks or answering interview questions.

3. Build More Than You Watch

Projects demonstrate your skills far better than completed playlists.

Publish everything on GitHub.

4. Start Applying Early

Begin applying during Month 5 rather than waiting until everything feels perfect.

Real interviews are one of the fastest ways to improve.
