In API caching, _________ is used to specify how long the response should be considered fresh.
- Cache-Control
- ETag
- Expires
- Last-Modified
In API caching, the "Expires" header is used to specify the date and time until which the cached response is considered fresh. It helps clients determine whether the cached data can still be used or if a new request to the server is required.
Mocking APIs is particularly useful in a __________ environment where the real API is not yet available or is undergoing changes.
- Development
- Production
- Staging
- Testing
In a testing environment, when the real API is not accessible or is undergoing changes, mocking APIs help simulate the expected behavior. This ensures that the application can be tested thoroughly without relying on the actual API.
When testing an API Gateway, what is the importance of evaluating its ability to handle service discovery?
- Fault Tolerance and Error Handling
- Scalability and Performance
- Security and Authentication
- Service Registration and Dynamic Routing
In API Gateway testing, evaluating the ability to handle service discovery is crucial as it ensures dynamic routing and efficient communication among services. This includes service registration and dynamic routing mechanisms.
Which aspect of an API is most crucial to consider when applying Boundary Value Analysis?
- API documentation completeness
- Error handling in the API
- Input values near the boundary limits
- Output values near the boundary limits
In Boundary Value Analysis, the emphasis is on testing input values near the boundary limits. This is critical as these values are more likely to expose errors or unexpected behavior in the API.
The evaluation of _________ is a key aspect of API testing, contrasting with the more isolated approach of unit testing.
- Contracts
- Dependencies
- Integration
- Responses
Detailed In API testing, the evaluation of contracts is crucial. Contracts define the expected interactions between different components of the system. API testing involves checking whether the API adheres to its defined contracts, ensuring proper communication and functionality. This is in contrast to unit testing, which often focuses on isolated components rather than their interactions.
How should error handling be approached when integrating a third-party API?
- Handle errors gracefully and provide meaningful feedback
- Ignore errors and log them for future analysis
- Propagate the errors to the end-user
- Retry the API call
Effective error handling is vital in API integrations. Handling errors gracefully and providing meaningful feedback to users helps in troubleshooting and resolving issues efficiently.
_________ plays a crucial role in API versioning, especially when deciding the lifecycle and deprecation policies for API versions.
- Authorization
- Configuration
- Documentation
- Metadata
Documentation is crucial in API versioning as it provides clear information about the API, including its lifecycle and deprecation policies, aiding developers in understanding changes.
In GraphQL, what is the role of a Schema?
- Define the data structure and types
- Execute queries
- Handle HTTP requests
- Store data in the database
A Schema in GraphQL defines the types of data that can be queried and the relationships between them. It serves as a contract between the client and server, specifying the structure of the API.
In API automation scripts, _________ are used to validate the response and ensure it meets certain criteria.
- Assertions
- Functions
- Loops
- Variables
In API automation, assertions are crucial for validating the response received from the API. They allow you to set criteria and ensure that the API response aligns with the expected results. This helps in verifying the correctness of the API behavior.
SOAP APIs enforce a strict _______ which is essential for enterprise-level web services.
- Language
- Protocol
- Schema
- Style
SOAP APIs enforce a strict schema, defining the structure of data exchanged between systems. This strict structure is crucial for enterprise-level web services, ensuring consistency and reliability in data communication.
