Google Professional Cloud Developer Question 265
Select 4Google Cloud PlatformYou are developing a cloud-native application on Google Cloud and want to ensure your application is thoroughly tested before deployment. Which approaches should you prioritize to validate the functionality and performance of your application in a cloud environment?
- A
Unit tests to verify individual components of your code in isolation.
- B
Integration tests to verify interactions between different services in your application.
- C
Load testing to assess how your application behaves under high traffic scenarios.
- D
End-to-end (E2E) tests to simulate real-world user interactions across the entire application.
- E
Skipping tests during Continuous Integration/Continuous Deployment (CI/CD) pipelines to save time.
Show answer and explanation
Correct answers: A, B, C, D
Explanation
Testing in a cloud environment involves multiple layers to ensure the application is reliable, performant, and user-friendly. Unit tests validate individual code components, integration tests check service interactions, load tests ensure scalability, and end-to-end tests verify the overall user experience. Skipping tests compromises the quality and stability of your application, especially in automated CI/CD pipelines.
- A. Correct.
Unit tests are essential for ensuring that individual components of your application work correctly in isolation. They are a fundamental part of testing.
- B. Correct.
Integration tests are necessary to validate how different services in your application interact and function together, which is critical in a distributed cloud environment.
- C. Correct.
Load testing is crucial to understand how your application performs under heavy traffic and ensures it can handle real-world usage at scale.
- D. Correct.
End-to-end tests help simulate the user journey across the application, providing confidence that the overall system works as expected.
- E. Incorrect.
Skipping tests during CI/CD pipelines is a bad practice that can lead to undetected bugs and reduced confidence in your deployment.
