100 Interview Questions for Automation Technologist

  1. What is your experience with different automation frameworks (e.g., Selenium, Appium, Cypress, Robot Framework)?

    • Answer: I have extensive experience with Selenium WebDriver, utilizing Java and Python bindings for web application automation. I'm also proficient in Appium for mobile testing (both iOS and Android), and have worked with Cypress for its speed and ease of use in frontend testing. My experience with Robot Framework is primarily in creating and maintaining test cases for integration testing, leveraging its keyword-driven approach for maintainability. I understand the strengths and weaknesses of each framework and can choose the most appropriate one based on project requirements.

  2. Describe your experience with CI/CD pipelines.

    • Answer: I have significant experience integrating automated tests into CI/CD pipelines using tools like Jenkins, GitLab CI, and Azure DevOps. I'm comfortable setting up pipelines, configuring triggers, managing build processes, and deploying artifacts. I understand the importance of continuous integration and continuous delivery for faster feedback loops and quicker releases. My experience includes setting up automated test execution as part of the pipeline, generating reports, and integrating with monitoring tools for improved visibility.

  3. How do you handle flaky tests?

    • Answer: Flaky tests are a major concern. My approach involves a multi-pronged strategy: First, I thoroughly investigate the root cause. Is it due to timing issues, race conditions, environmental factors (network, database), or poorly written test code? I use debugging tools and logging extensively. Second, I improve the test code itself, making it more robust and less reliant on timing. I might incorporate explicit waits, retries with backoff, and better error handling. Finally, I might implement strategies to isolate and identify flaky tests using tools that track test history and stability metrics, allowing for focused remediation efforts.

  4. Explain your understanding of different testing types (unit, integration, system, end-to-end).

    • Answer: Unit testing focuses on individual components or modules of the application, ensuring they function correctly in isolation. Integration testing verifies the interaction between different modules. System testing evaluates the entire system as a whole, ensuring all components work together as expected. End-to-end testing simulates real-world user scenarios, testing the entire application flow from start to finish. I understand the importance of each level of testing and how they contribute to a comprehensive testing strategy.
