Complete the code to identify the main challenge in end-to-end testing of microservices.
The biggest challenge in end-to-end testing microservices is [1].
Service dependencies cause complexity in end-to-end tests because multiple services must work together correctly.
Complete the code to describe a common strategy to isolate microservices during end-to-end testing.
A common strategy to isolate microservices is to use [1] to simulate dependent services.Service mocks simulate dependent services to isolate the service under test.
Fix the error in the statement about end-to-end test flakiness.
End-to-end tests are often flaky because of [1] in microservices communication.
Unreliable network conditions cause flakiness in tests due to timeouts or failures.
Fill both blanks to complete the sentence about test data management.
Managing [1] is hard because microservices have [2] data stores.
Test data management is difficult because each microservice often has its own independent data store.
Fill all three blanks to complete the sentence about test environment setup.
To reduce flakiness, tests should run in [1] environments with [2] services and [3] network conditions.
Isolated environments with mocked services and stable network conditions help reduce test flakiness.
