  • Learn to debug and troubleshoot advanced Selenium errors.

Day 4: Understanding Test Automation Frameworks

• Key Topics to Cover:
  • What is a test automation framework?
  • Designing frameworks using Page Object Model (POM).
  • Integrating test frameworks with tools like TestNG, JUnit, or PyTest.
  • Reporting tools like Allure or Extent Reports.
• Action Plan:
  • Create a simple test framework with POM and TestNG.
  • Generate detailed reports for executed test cases.
  • Study how frameworks are structured and implemented in real projects, especially in Agile environments.

Day 5: Master API Testing and CI/CD Integration

  • Tools like Jenkins and Git for version control.
• Action Plan:
  • Write test cases for sample APIs using Postman or RestAssured.
  • Understand how CI/CD pipelines integrate with automation frameworks.
  • Set up a Jenkins job to execute automation test scripts.

Day 6: Preparing for Behavioral and Scenario-Based Questions

• Key Topics to Cover:
  • Common behavioral questions: "Tell me about a challenging project and how you handled it."
  • Scenario-based questions like "How would you automate a testing process from scratch?"
  • Problem-solving approaches in testing.
• Action Plan:
  • Prepare STAR (Situation, Task, Action, Result) responses for behavioral questions.
  • Review common automation testing scenarios and think through solutions.
  • Practice explaining your thought process clearly and confidently.

Day 7: Mock Interviews and Final Revision
