_________ in versioning ensures that older versions of the API function correctly even after new versions are released.
- Backward Compatibility
- Endpoint
- Forward Compatibility
- Payload
Backward compatibility in versioning ensures that older versions of the API continue to function correctly even after new versions with updated features are released. This is crucial to prevent disruptions for existing clients using the API and promotes a smooth transition to newer versions.
What is Equivalence Partitioning in the context of API testing?
- A method for load testing APIs
- A method of dividing input values into groups to reduce test cases
- A process of debugging API endpoints
- A technique for analyzing API response times
Equivalence Partitioning is a testing technique where input values are divided into classes or partitions, allowing efficient testing of representative values from each class. It helps reduce the number of test cases while ensuring adequate coverage.
For a holistic view of API performance, integration of _________ data with monitoring tools is crucial.
- Business Intelligence Data
- Infrastructure Monitoring Data
- Security Audit Logs
- User Experience (UX) Metrics
Integrating infrastructure monitoring data with API performance tools is essential for a comprehensive view. It helps in identifying bottlenecks, optimizing resources, and ensuring overall system reliability.
How does Consumer-Driven Contract Testing benefit microservices API testing?
- Ensures Compatibility
- No Interaction with Providers
- Shared Consumer and Provider Contracts
- Validates Only Provider
Consumer-Driven Contract Testing involves shared contracts between consumers and providers, ensuring compatibility in APIs.
In DevOps, at which stage is API testing typically integrated?
- Deployment
- Development
- Planning
- Testing
In DevOps, API testing is typically integrated during the testing stage. This ensures that APIs are tested thoroughly before the application is deployed, helping to identify and fix issues early in the development lifecycle. Testing APIs at this stage contributes to the overall quality and reliability of the software.
In advanced API mocking, the concept of _________ is used to dynamically alter the mock responses based on the request data.
- Dynamic Mapping
- Fixed Data
- Immutable Results
- Static Responses
Advanced API mocking involves dynamic mapping, where mock responses are altered based on the input request data. This enables testers to create more sophisticated scenarios and closely mimic the behavior of real APIs that may produce different results based on input parameters.
What is the primary purpose of API testing?
- To ensure that APIs work as intended
- To test the database schema of the application
- To validate the performance of a web application
- To verify the functionality of the user interface
API testing primarily focuses on checking whether APIs function as expected, ensuring their reliability and correctness.
_________ is a key strategy in API testing that involves dividing input data into various partitions to reduce the number of test cases.
- Boundary Value Analysis
- Equivalence Partitioning
- Negative Testing
- Positive Testing
Boundary Value Analysis is a testing technique that involves selecting test cases at the boundaries of input partitions. It helps identify potential errors at the edges of input ranges, leading to more comprehensive testing.
Which type of testing typically requires more knowledge of the internal code structure?
- Acceptance testing
- Integration testing
- System testing
- Unit testing
Unit testing requires a deep understanding of the internal code structure as it involves testing individual functions or methods in isolation. Testers need to have knowledge of the code to create effective unit tests.
When encountering a scenario where a GraphQL query returns unexpected null fields, what aspect of the API should be primarily investigated?
- Data Fetching Mechanism
- Query Execution Engine
- Resolver Functions
- Schema Definition
In GraphQL, the query execution engine is responsible for executing the requested query and handling null fields. Investigating the query execution engine can help identify issues related to unexpected null fields.
