Selenium API Development & Integration 5

Question 1

In a Selenium test framework, what is the primary benefit of creating an 'API client helper class' for common API operations?

Accepted Answer

It centralizes API call logic for reuse and easier maintenance

Answer

An API client helper class centralizes repeated API call logic so changes to the API require updates in only one place rather than across all tests.

Question 2

When an API response contains paginated data, how should a Selenium test framework handle retrieving all records?

Accepted Answer

Implement a loop that calls the API repeatedly until no next-page token is returned

Answer

Handling pagination requires iterating through pages using continuation tokens or page numbers until the API indicates no more data remains.

Question 3

What is the role of an 'idempotency key' when making API calls within Selenium test automation?

Accepted Answer

It ensures that retrying a request does not create duplicate resources

Answer

An idempotency key lets a server recognize duplicate requests and return the original response without repeating the operation, preventing duplicate resource creation.

Question 4

Which assertion approach is most appropriate when a Selenium test validates that an API response contains a specific nested JSON field?

Accepted Answer

Use JSONPath expressions to extract and assert the specific field value

Answer

JSONPath expressions allow precise navigation and extraction of specific fields within nested JSON structures for targeted assertions.

Question 5

In API testing integrated with Selenium, what does 'rate limiting' mean and how should tests handle it?

Accepted Answer

Server-enforced request caps; tests should include retry logic with backoff when receiving 429 responses

Answer

Rate limiting restricts how many API requests a client can make in a time window; tests receiving HTTP 429 (Too Many Requests) should implement exponential backoff retry logic.
