 ✅ If you're preparing for SDET roles , mastering these topics is a must: 1️⃣ OOPS Concepts: Understand Inheritance, Polymorphism, Abstraction, and Encapsulation. Real-world examples matter! 2️⃣ Collections Framework: Know List, Set, Map, and their implementations (ArrayList, HashMap, etc.). Don’t forget sorting and filtering using streams. 3️⃣ Exception Handling: Master try-catch, finally, custom exceptions, and best practices for error handling. 4️⃣ File Handling: Learn to read/write files using File, BufferedReader, BufferedWriter, and NIO. 5️⃣ Multithreading & Concurrency: Understand Thread, Runnable, ExecutorService, and synchronization techniques. 6️⃣ Java Streams & Lambda Expressions: Essential for writing clean and concise code during test automation. 7️⃣ Framework Integration: Learn how Java powers tools like Selenium, Rest Assured, and TestNG/Cucumber. 8️⃣ Design Patterns: Familiarize yourself with Singleton, Factory, and Page Object Model (POM) for test automation design. ✨ Bonus: Brush up on JVM Architecture, Garbage Collection, and Java 8+ Features (like Optional and Functional Interfaces).

Example: Input: arr = [2, 4, 1, 5, 3, 6] Output: 4 Explanation: The sorted array in descending order is [6, 5, 4, 3, 2, 1]. The third largest number is 4. 2. Given an array of strings, group the strings that are anagrams of each other. Example: Input: arr = ["eat", "tea", "tan", "ate", "nat", "bat"] Output: [["eat", "tea", "ate"], ["tan", "nat"], ["bat"]] Explanation: The groups of anagrams are ["eat", "tea", "ate"], ["tan", "nat"], and ["bat"]. 3. Given an array of integers, find the largest number that does not have any duplicates in the array. Example: Input: arr = [4, 3, 2, 7, 3, 4, 8] Output: 8 Explanation: The unique numbers are [2, 7, 8], and the largest among them is 8. ✅Follow Kushal Parikh for insightful content on Software Testing & don't forget to check out my topmate.io link: https://lnkd.in/dEDZxwwF 🚀 𝐔𝐥𝐭𝐢𝐦𝐚𝐭𝐞 𝐐𝐀/𝐒𝐃𝐄𝐓 𝐃𝐢𝐠𝐢𝐭𝐚𝐥 𝐊𝐢𝐭 https://lnkd.in/dYPWn5xE 🚀 𝐔𝐥𝐭𝐢𝐦𝐚𝐭𝐞 𝐐𝐀/𝐒𝐃𝐄𝐓 𝐈𝐧𝐭𝐞𝐫𝐯𝐢𝐞𝐰 𝐏𝐫𝐞𝐩𝐚𝐫𝐚𝐭𝐢𝐨𝐧 𝐊𝐢𝐭 https://lnkd.in/dskETMfb 🚀 𝐀𝐮𝐭𝐨𝐦𝐚𝐭𝐢𝐨𝐧 𝐓𝐞𝐬𝐭𝐢𝐧𝐠 𝐏𝐫𝐚𝐜𝐭𝐢𝐜𝐞 𝐖𝐞𝐛𝐬𝐢𝐭𝐞𝐬 https://lnkd.in/dBzp5RAy 🚀 𝐀𝐓𝐒 𝐑𝐞𝐬𝐮𝐦𝐞 𝐓𝐞𝐦𝐩𝐥𝐚𝐭𝐞𝐬 𝐊𝐢𝐭 https://lnkd.in/d3ywVEhS 𝐇𝐚𝐩𝐩𝐲 𝐓𝐞𝐬𝐭𝐢𝐧𝐠! 😎 #sdet #autoamtion #testing #qa #testers #testingcommunity

[Imp SDET Interview Question] How Would You Design a Test Script to Validate a Login Page? Ans: My approach for effective, reliable test coverage: 1. Identify Basic Elements First, I will focus on elements like username, password fields, and login button. It's critical to ensure each element is uniquely identifiable, using stable locators (like IDs or CSS selectors) that won’t change frequently. 2. Valid Inputs Scenario Enter valid credentials and verify that the login is successful. I will check for the landing page, confirming it loads as expected. I will also add assertions for any welcome messages or redirects that are supposed to happen post-login. 3. Negative Test Cases Next, I will introduce scenarios where incorrect credentials are used: Blank fields: Verify that trying to log in with empty fields triggers the right error messages. Invalid Username/Password Combinations: Check for scenarios like invalid usernames, correct username with an incorrect password, and so on. 4. Boundary and Edge Cases Testing with inputs on the boundary is essential. I will include tests for: Max and min length: Ensure username and password fields enforce length limits. Special characters: Ensure inputs with special characters behave as expected. 5. Security Checks Security is always a top priority. I will add scenarios to ensure: SQL Injection Protection: Validate that the app does not accept SQL-like inputs. Brute Force Protection: Test for account lockouts after multiple failed attempts. Session Management: Ensure the user session remains secure and consistent. 6. Usability and Accessibility I will finish by validating usability and accessibility, checking that error messages are clear, fields have descriptive labels, and the UI handles edge cases gracefully. #Testing #SDET #QA #LoginPage #Automation #Python #Selenium

💡 Mastering Java Exceptions: A Must-Know for Every QA & SDET 💡 As QA engineers and SDETs, understanding Java Exceptions is vital for debugging, writing robust automation frameworks, and ensuring clean error handling. Here’s a quick guide to Java Exceptions and why they matter: 📚 Types of Exceptions in Java: 🌟 Checked Exceptions 👉 Compile-time exceptions (e.g., IOException, SQLException). 👉 Must be handled using try-catch or throws. 👉 Ensures developers anticipate and manage potential issues. 🌟 Unchecked Exceptions 👉 Runtime exceptions (e.g., NullPointerException, ArrayIndexOutOfBoundsException). 👉 Caused by programming errors, often not explicitly handled. 🌟 Errors 👉 Critical issues (e.g., OutOfMemoryError, StackOverflowError). 👉 Typically indicate problems beyond application control. 🎯 Why QA & SDETs Should Master Exceptions ✨ Debugging Power: Trace failures effectively using stack traces. ✨ Framework Stability: Handle unexpected scenarios gracefully in test automation. ✨ Clean Code: Avoid "silent failures" by implementing meaningful exception handling. ✨ Custom Exceptions: Define and throw your own exceptions for better test feedback (e.g., TestDataNotFoundException). 🛠 Pro Tip: ☘️ Use finally blocks or try-with-resources for resource cleanup, and always log exceptions with meaningful messages to avoid debugging nightmares! ☘️ Understanding Java Exceptions is more than just theory—it’s your toolkit for building resilient automation frameworks that inspire confidence in your testing.

If yes how? 2) How do you make sure 3rd party APIs like payment gateways are integrated for Test Automation Framework? 3) Do you prefer to automate it using UI or API and Why? 4) Why did Amazon moved back to Monolithic architecture? Can you justify? 5) When should use LomBok for POJO classes instead of Builder Pattern? 6) How do you manage a CI/CD pipeline when high-priority scenarios fail during execution? 7) Write the code snippet for passing values 1 and 2 to the parameters val1 and val2 through the XML file. 8) If you are using Selenium WebDriver, How do you create a Test Automation Framework for a page having 700 unique webelements? 9) How to keep API Tests idempotent? 10) What happens when you write "new ChromeDriver();"? 11) Wrote a SQL Query using 3 Inner Joins (Data was given by the interviewer) 12) Explain the use and implementation of Response & Request Spec in RestAssured?

🚀 SDET/QA Basic API Testing - Interview Q&A ! 💻 🙋♂️ 📚 🛑 - Quick 2 Question & Answer- 2-Min Learnings 🛑DAY-5🛑 1️⃣ Difference Between 4XX & 5XX Error code ❓ - A 4xx code indicates an error caused by the user/Client, whereas 5xx codes tell the client that they did everything correctly and it's the server itself who caused the problem. - In simple word- 400 series indicate that error is there at Client side i.e. we are sending something wrong, Where as 500 series indicate that error is at server side(Server down/Malfunctioning) but we/client is sending correct data. 2️⃣ Difference Between 401 & 403 error code ? - 401 Unauthorized response should be used for missing or bad authentication, i.e. User/Client is UnAuthorized, He/Client doesn't have proper AuthToken/Authentication. - where as a 403 Forbidden response should be used afterwards, when the user is authenticated but isn’t authorized to perform the requested operation on the given resource. i.e. User/Client is Authorized, But doesn't have proper access for the given resource/file. 💼 Course Details: Learn to become expert in API Testing API Testing with Java - https://lnkd.in/dsdFq7R5 API Testing with Python - https://lnkd.in/dq8kEzgX #SDET #Learning #QA #Tester #Interview #SoftwareTesting #Testing #QALead #TestLead #Automation #softwareTestingClub #APIAutomation #SDETInterviewTips #SDE #QualityAssurance #ISTQB #CAREER #JOBINTERVIEW #ManualTesting #JobInterview #TestingInterview #APITestingJourney 🚀
