Automated testing strategy in Microservices - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the main goal of an automated testing strategy in microservices?

To ensure each microservice works correctly on its own and when integrated with others, catching bugs early and speeding up development.

beginner

Name the four common types of automated tests used in microservices.

Unit tests, Integration tests, Contract tests, and End-to-End tests.

intermediate

Why are contract tests important in a microservices automated testing strategy?

They verify that the communication between microservices follows agreed rules, preventing integration failures.

intermediate

What role does Continuous Integration (CI) play in automated testing for microservices?

CI automatically runs tests on new code changes to catch errors early and ensure code quality before deployment.

advanced

How can test data management improve automated testing in microservices?

By providing consistent, isolated, and realistic data for tests, it helps tests run reliably and independently.

Which test type focuses on testing a single microservice's internal logic?

A Unit test

B End-to-End test

C Contract test

D Load test

Unit tests check the smallest parts of code, like functions or methods, inside one microservice.

What does a contract test verify in microservices?

A User interface behavior

B Performance under load

C Database schema correctness

D Communication agreements between services

Contract tests ensure that microservices communicate using agreed formats and protocols.

Why is running automated tests in a CI pipeline beneficial?

A It requires manual test execution

B It catches bugs early and improves code quality

C It delays feedback on code changes

D It replaces the need for any manual testing

CI pipelines run tests automatically on code changes to find bugs quickly and maintain quality.

Which test type simulates real user scenarios across multiple microservices?

A Unit test

B Integration test

C End-to-End test

D Contract test

End-to-End tests check the whole system working together like a user would experience it.

What is a key challenge automated testing must address in microservices?

A Managing dependencies and data across services

B Avoiding any test automation

C Testing only one service at a time

D Ignoring service communication

Automated tests must handle dependencies and data sharing between microservices to be effective.

Explain the layers of automated testing you would implement for a microservices system and why each is important.

Think about testing from smallest parts to the whole system.

Describe how Continuous Integration supports an automated testing strategy in microservices.

Consider the role of automation in the development workflow.
