Google Professional Cloud Developer Question 282
Single answerGoogle Cloud PlatformYou are developing a cloud-native application that uses Google Cloud Firestore as its database. To ensure the reliability of your application, you want to perform integration testing without incurring additional costs or modifying live data. How can you achieve this using Google Cloud's tools?
- A
Use the Firestore Emulator to simulate the Firestore environment locally for integration testing.
- B
Use a separate Firestore instance in a different project specifically for testing purposes.
- C
Directly use your production Firestore instance for integration testing but clean up test data afterward.
- D
Use a Google Cloud Storage bucket to simulate Firestore for integration testing.
Show answer and explanation
Correct answer: A
Explanation
The Firestore Emulator is part of the Google Cloud Emulator Suite and allows developers to perform integration testing locally by simulating the Firestore service. This avoids the risk of modifying live data, eliminates costs associated with testing in the cloud, and provides a controlled environment for testing. Using the emulator is the best practice for integration testing with Firestore.
- A. Correct.
Correct. The Firestore Emulator is designed to simulate the Firestore environment locally and is ideal for performing integration tests without affecting live data or incurring additional costs.
- B. Incorrect.
Incorrect. While using a separate Firestore instance might work, it would incur additional costs and could still lead to configuration or access issues. It is not the recommended approach for integration testing.
- C. Incorrect.
Incorrect. Using the production Firestore instance for testing is risky as it may impact live data and introduce security and reliability concerns during testing.
- D. Incorrect.
Incorrect. Google Cloud Storage is a different service and cannot simulate Firestore's NoSQL database capabilities. It is not suitable for testing Firestore integrations.
