SDET preguntas y respuestas de entrevista
Pregunta 6. What are the benefits of using version control systems in test automation?
Version control systems (e.g., Git) enable tracking changes, collaboration, and maintaining a history of the test automation code, making it easier to manage and roll back changes.
Example:
Using Git to track changes in test scripts and collaborate with team members.
Pregunta 7. Explain the concept of 'headless' browser testing.
Headless browser testing refers to running browser tests without a graphical user interface, which is useful for faster test execution, especially in continuous integration environments.
Example:
Running Selenium tests in headless mode without launching a visible browser window.
Pregunta 8. What is a mock object in testing, and how is it useful?
A mock object is a simulated object used to mimic the behavior of real objects in a controlled way. It helps isolate the code being tested and ensures that it interacts correctly with dependencies.
Example:
Creating a mock database object to simulate database interactions during unit testing.
Pregunta 9. How do you handle flaky tests in your test suite?
Addressing flaky tests involves identifying and fixing the root cause, introducing wait mechanisms, and implementing test retry strategies to improve test stability.
Example:
Setting up a retry mechanism for a test that occasionally fails due to timing issues.
Pregunta 10. What is Continuous Integration (CI) and how does it benefit test automation?
Continuous Integration is the practice of frequently integrating code changes into a shared repository, and it benefits test automation by ensuring that tests are run automatically whenever new code is committed, catching issues early in the development process.
Example:
Using Jenkins or Travis CI to trigger automated tests upon code commits.
