By

  Once you're comfortable with basic Selenium functionalities, you can gradually explore and master advanced concepts to become proficient in Selenium automation testing.


Basic Concepts: Locators: Understanding how to locate elements on a web page using various locators such as ID, class name, CSS selector, XPath, etc.

WebDriver: Working with WebDriver to interact with web elements and perform actions like clicking buttons, entering text, etc.

Handling Alerts and Pop-ups: Dealing with alerts, confirmation dialogs, and pop-ups during test execution.

Synchronization: Understanding implicit and explicit waits to synchronize test execution with the web page's loading status.

Handling Frames and Windows: Switching between frames and managing multiple browser windows or tabs.

Handling Forms: Filling out and submitting web forms using Selenium.

Navigation: Navigating through different pages within a web application using Selenium commands. Advanced Concepts:

Page Object Model (POM): Implementing the POM design pattern to organize and maintain Selenium code for better readability, maintainability, and reusability.

TestNG or JUnit: Learning advanced testing frameworks like TestNG or JUnit for better test management, parallel execution, reporting, and parameterization.

Data-Driven Testing: Implementing data-driven testing approaches to run the same test with multiple sets of data, often using external data sources like Excel, CSV, or databases.

Cross-Browser Testing: Executing tests across multiple browsers (Chrome, Firefox, Safari, etc.) and platforms (Windows, macOS, Linux).

Parallel Execution: Running tests concurrently across multiple browsers or environments to reduce test execution time.

Handling Dynamic Elements: Dealing with dynamic elements on web pages whose attributes change dynamically during runtime.

Advanced Interactions: Performing complex interactions such as drag and drop, mouse hovering, keyboard actions, etc.

Browser Profiling: Utilizing browser profiling tools to analyse and optimize test execution performance.

Logging and Reporting: Implementing logging mechanisms and generating detailed test reports for better debugging and analysis.

Continuous Integration (CI) Integration: Integrating Selenium tests with CI tools like Jenkins, Travis CI, or CircleCI for automated test execution.


If Advanced or Basic, Tester should possess the Basic grasp of these followed concepts and acquire the Basic Foundational knowledge among following areas.

  1. Programming Language Proficiency: Ensure you have a good grasp of the programming language you're using with Selenium (commonly Java, Python, C#, or JavaScript). Understanding data types, control structures, functions/methods, and object-oriented programming concepts is essential.


  2. HTML, CSS, and DOM: Familiarize yourself with basic web technologies like HTML (Hypertext Markup Language) and CSS (Cascading Style Sheets). Understanding the Document Object Model (DOM) and how web elements are structured on a page is crucial for effective element identification and manipulation with Selenium.


  3. Web Technologies: Gain basic knowledge of web technologies and protocols such as HTTP/HTTPS, client-server architecture, web servers, and browsers. Understanding how web applications function at a high level will provide valuable context for Selenium automation.


  4. Browser Developer Tools: Learn how to use browser developer tools (e.g., Chrome DevTools, Firefox Developer Tools) to inspect web elements, analyse network traffic, debug JavaScript, and troubleshoot issues. This skill is invaluable for Selenium automation debugging and troubleshooting.


  5. Software Testing Fundamentals: Understand fundamental software testing concepts such as test planning, test case design, test execution, test automation strategies, and test result analysis. This knowledge will help you design effective Selenium tests and interpret their results accurately.


  6. Version Control Systems: Familiarize yourself with version control systems like Git and concepts such as repositories, commits, branches, and merges. Version control is essential for collaboration, code management, and tracking changes in your Selenium automation project.

  7. Debugging Techniques: Develop skills in debugging code, identifying and fixing errors, and troubleshooting issues. Being proficient in debugging will help you diagnose and resolve issues encountered during Selenium test development and execution.


  8. Community Resources and Documentation: Explore Selenium documentation, tutorials, forums, and online communities to learn from others, share experiences, and stay updated on best practices and emerging trends in Selenium automation.


  9. Project Management Skills: Develop project management skills such as task prioritization, time management, and collaboration. Effective project management ensures the successful implementation and maintenance of Selenium automation projects in real-world scenarios.

Had you to design test cases for a complex feature. What factors did Tester consider, and how did prioritize test scenarios?

  Take an instance as new application has integrated into existing applications(i,e., Running on real time )Customer want to integrate their application into third party vendors in order to let the customer order their needs through our created app itself. Factors Consisdered : Error Handling , Functional Requirements , Edge cases , Non-Functional Parameters . Transaction Flow Flow1: Customer Land on third party vendors app and start picking their items. Flow2 : Picked Items has to go Cart Page and can see number of items added by visually. Flow3: Once click to checkout , it will allow the user to input their card details and processing transaction. Flow4:Once Transactions done, newly created app show the details of the order and online tracking number . Prioritize scenerios based on the Business Emergency and needs ,well in briefly communicate to team members to identify the Critical paths and prioritize the that test suite first and Start  the execution based on what need to...

Static and Non-Static

By
  What is the purpose of the static keyword in Java? The static keyword is used to declare class-level variables and methods . They belong to the class rather than instances of the class and can be accessed using the class name. can we use the static keyword for package level access? In Java, the static keyword is not used for controlling access levels. The static keyword is primarily used to define class-level members, such as variables and methods, that are associated with the class itself rather than with instances of the class. The concept of access levels, on the other hand, is controlled by access modifiers. public class MyClass {     public static int publicStaticVariable = 10;     static int packagePrivateStaticVariable = 20; // package-private by default     private static int privateStaticVariable = 30; } To summarize, while static is used to define class-level members, access modifiers (public, protected,...

Pre conditions and Post conditions in Test Ng.

By
Pre conditions and PostConditions in Test Ng. Vision of Preconditions and Postconditions: 👉 Ensuring Test Isolation: By using preconditions and postconditions, you ensure that each test method is executed in isolation, with a clean and consistent state. 👉Promoting Reusability: Setup and teardown tasks defined in preconditions and postconditions can be reused across multiple test methods, promoting code reuse and reducing redundancy. 👉Maintainability: Clearly defined preconditions and postconditions enhance the maintainability of test code. Changes or additions to the setup and cleanup logic can be made centrally in these annotated methods. TestNG PreConditions and PostConditions flow.   Before Suite (once) Before Test (once for each <test> in the suite) Before Class (once for each class with test methods in the <test> ) Before Method (before each test method) Test method execution After Method (after each test method) After Class (after all test methods in ...
