Java Roadmap for SDET Superstars!

Java Roadmap for SDET Superstars!

Your ultimate journey to mastering Java for test automation!

Step 1: Java Basics – The Foundation

Learn the grammar of Java
📚✨

  • 🧮 Variables & Data Types (int, float, boolean)
  • ➕ Operators (+, -, *, /, %)
  • 🔁 Loops (for, while, do-while)
  • 🧠 Conditions (if-else, switch)
  • 📦 Arrays & Strings

Step 2: OOP – Think Like a Developer

  • 👪 Inheritance
  • 🎭 Polymorphism
  • 🧬 Abstraction & Interfaces
  • 🔐 Encapsulation

Step 3: Exception Handling – Be Ready for Chaos

Handle the unexpected like a pro!
🧨⚠️

  • try, catch, finally
  • throw and throws
  • 🚨 Custom Exceptions

Step 4: Collections – Organize Like a Boss

Work with lists, maps & sets like a data wizard
📦🪄

  • 🗃️ List, Set, Map
  • 🌀 ArrayList, HashMap, HashSet
  • 🔁 Iteration (for-each, iterator)
  • 🧠 Sorting & Filtering


Step 5: Java 8+ – Modern & Cool Features

Level up with Java 8 magic
⚡🧙‍♂️

  • 🌀 Lambda Expressions
  • 🌊 Streams API
  • ✅ Optional Class
  • ↪️ Method References
  • 🧩 Functional Interfaces

Step 6: File Handling – Read, Write, Repeat

Work with text, CSV, and properties files
📁✍️

  • 📖 FileReader, BufferedReader
  • ✍️ FileWriter, PrintWriter


Step 7: Threads – Think Parallel

When your tests want to multitask!
🧵⏱️

  • 🧵 Creating Threads
  • ⚙️ Runnable Interface
  • 🔒 Synchronization Basics

Step 8: Java Utilities – Handy Tools

🛠️🧰

  • 📏 Math, Arrays, Collections
  • 🔤 StringBuilder vs StringBuffer
  • 📅 Date, LocalDate, SimpleDateFormat

Step 9: Maven – Build It Up

Dependency management = peace of mind
⚙️🧩

  • 🛠️ pom.xml basics
  • 📦 Adding dependencies
  • 🧪 Running tests via Maven

Step 10: Unit Testing – Test Like a Tester

JUnit or TestNG = your new best friends
✅🧪

  • @Test, @Before, @After
  • 🧮 Assertions
  • 🧪 TestNG DataProviders
  • 🧩 Parameterized Tests

Step 11: Automation Framework Essentials

Build a real-world testing framework
🏗️📋

  • 🧱 Page Object Model (POM)
  • ⚙️ BasePage, DriverFactory
  • 📝 Logging with Log4j
  • 📊 Reporting (ExtentReports or Allure)

Step 12: Tool Integration – SDET Toolbox

Connect everything like a DevOps wizard
🧰🌐

  • 🕸️ Selenium WebDriver
  • 🐛 Cucumber for BDD
  • 🔌 REST Assured for APIs
  • ☁️ Jenkins for CI
  • 🐙 Git & GitHub

Step 13: Practice & Projects – Become a Rockstar

Practice > Theory!
🎯

  • ✔️ Build an end-to-end test automation project
  • 🧠 Solve coding challenges (LeetCode, HackerRank)
  • 🎤 Prepare for real-world SDET interview questions

Bonus (Optional Advanced Topics)

🚀

  • 🪞 Java Reflection
  • 🧵 Thread Pools
  • 🧪 Custom Annotations
  • 🏗️ Design Patterns (Factory, Singleton)
  • 🌱 Spring Boot (if backend testing interest)

Let’s Wrap It Up!

You're now ready to conquer the SDET world with Java
🎓✨

Keep coding. Keep testing. Keep growing.
