- while loop
Avoid memorizing solutions. Instead, practice solving them on paper to reinforce your understanding and improve problem-solving skills.
Theory Questions on OOP Concepts
Providing a four-dimensional answer to each OOP concept showcases your depth of knowledge and understanding:
- Theory: Explain the concept in detail.
- Selenium Usage: Example – WebDriver extends SearchContext
- Project Usage: Example – Testcases extends BaseHooks
- Java Usage: Example – List extends Collection
Selenium WebDriver Questions:
Key Areas to Focus On
- WebTable: How to handle dynamic web tables effectively.
- Switch Window Handles: Various methods (e.g., Set -> List -> get, iterator -> next, for-each -> title -> break).
- XPath Patterns: Using following and sibling.
Additional Learning
- ChromeOptions: Understand and explain its use, enhancing your capability to configure browser settings programmatically.
Framework Questions:
Common Framework Explanation
When asked to explain your framework, provide a detailed description of its daily execution process:
- Jenkins Job/Pipeline:
- Triggered at 10 PM IST, a Jenkins job or pipeline initiates the process.
- Git WebHook pulls the latest code to the Jenkins workspace, ensuring the most recent updates are included.
- Maven Goal (test):
- The Maven goal ‘test’ calls testng.xml, which organizes and runs the test cases.
- Executes test cases with TestNG annotations, automating the testing process.
- Browser Launch:
- WebDriver initiates the browser, setting the stage for automated testing.
- Data Handling:
- Data fetched from XLS files using Apache POI is passed to the Data Provider, ensuring data-driven testing.
- Test Execution:
- Each step is reported with snapshots via ExtentReports, providing detailed and visual feedback.
- Final Reporting:
- HTML report generated by Jenkins is shared through email, summarizing the test results.
Physical Structure of Framework
- Hooks: Setup and teardown actions.
- Tests: Actual test cases.
- Wrappers: Helper functions and utilities.
- Utils: Common utilities.
- Features: Specific functionalities tested.
By understanding and preparing for these aspects, you can navigate the interview process in service companies with confidence and clarity.
