How does the concept of 'Shift Left' apply to API testing in CI/CD?
- Accelerating Test Execution
- Emphasizing Manual Testing in Later Stages
- Performing Testing Earlier in the Lifecycle
- Shifting Testing Responsibilities to Developers
'Shift Left' in API testing means involving developers earlier in the testing process, promoting collaboration, and finding defects sooner in the SDLC.
Ensuring _________ in API responses is vital when testing APIs designed to handle large volumes of data.
- Accuracy
- Consistency
- Integrity
- Redundancy
Ensuring integrity in API responses is vital when testing APIs designed to handle large volumes of data. Data integrity ensures that the data remains accurate and unaltered during transfer and processing.
To simulate external API dependencies in a controlled manner, _________ is often used in test environments.
- Mocking
- Polyfilling
- Shimming
- Transpiling
In test environments, "Mocking" is commonly used to simulate external API dependencies. Mocking allows developers to create controlled and predictable responses from external services during testing, ensuring that the application behaves as expected without relying on actual external APIs.
Testing for _________ involves ensuring that API responses are stored and retrieved correctly from the cache.
- Cache Eviction
- Cache Hit
- Cache Miss
- Cache Validation
Testing for "Cache Hit" involves ensuring that API responses are correctly retrieved from the cache when a request matches a cached resource. It verifies that the caching mechanism is working as intended.
What is the key advantage of using mock APIs in parallel development environments?
- Enhance collaboration among developers
- Ensure real-time data synchronization
- Minimize code documentation efforts
- Reduce dependencies on external systems
The primary advantage of mock APIs in parallel development is the reduction of dependencies on external systems. This independence allows developers to work simultaneously without waiting for external services, fostering efficient parallel development environments.
Accurate and up-to-date API documentation is vital for testers to understand the ________ and ________ required by different API endpoints.
- Endpoints, Parameters
- Inputs, Outputs
- Methods, Functions
- Requests, Responses
Testers must be aware of the endpoints and parameters required by different API endpoints to perform accurate testing. Endpoints define the specific locations or paths that the API serves, and parameters specify the necessary information for successful API calls. Accurate documentation ensures testers have the right insights for testing different aspects of the API.
How would you approach API testing in a DevOps environment where rapid releases are a priority?
- Automate testing processes to achieve continuous integration and continuous testing
- Conduct thorough manual testing before each release
- Rely on user feedback to identify issues after release
- Skip testing to expedite the release process
In a DevOps environment with a focus on rapid releases, automated testing is essential for achieving continuous integration and continuous testing. Automation ensures faster feedback on code changes, reduces the risk of defects, and accelerates the release cycle, aligning with the principles of DevOps.
In API test automation, what is a major challenge associated with handling external dependencies?
- Consistent availability of external resources
- Ensuring a stable testing environment
- Handling external dependencies asynchronously
- Limited impact of external dependencies
A major challenge is ensuring a stable testing environment by handling external dependencies. Test automation needs to account for the availability and stability of external resources, ensuring reliable and consistent test results.
In API performance testing, what does 'latency' refer to?
- Code Compilation Time
- Data Encryption
- Processing Speed
- Time Delay in Data Transmission
Latency in API performance testing refers to the time delay or lag in data transmission between the client and server. It represents the time taken for a request to travel from the client to the server and back, including the processing time. Minimizing latency is crucial for optimizing API performance and ensuring a prompt response to user requests, contributing to a smoother user experience.
When an API is deprecated, ensuring _________ compatibility is critical for maintaining user trust and minimizing disruption.
- Backward
- Forward
- Cross-browser
- Legacy
The correct option is "a) Backward." Ensuring backward compatibility means that the deprecated API continues to work seamlessly with existing code, preserving functionality for users who have not yet migrated to the updated version. This is essential for maintaining trust and minimizing disruptions during transitions.
