Which HTTP method is commonly used to retrieve data from a server?
- DELETE
- GET
- POST
- PUT
The HTTP method "GET" is commonly used to retrieve data from a server. When a client sends a GET request, it is asking the server to send back a representation of a specified resource. This method is considered safe and idempotent, meaning multiple identical requests should have the same effect as a single request.
In API testing, the focus is more on _________, whereas unit testing is concerned primarily with the functionality of individual units.
- Business logic
- Data formats and protocols
- Database queries
- User interfaces
API testing involves testing the Application Programming Interface to ensure proper communication between different software components. It focuses on data formats, protocols, and interactions, unlike unit testing that primarily deals with the functionality of isolated units.
How does GraphQL handle data fetching from multiple resources?
- Relies on WebSockets
- Requires Multiple Endpoints
- Uses a Third-party Library
- Utilizes a Single Request
GraphQL allows clients to request data from multiple resources in a single query, reducing the need for multiple requests. This feature improves efficiency and minimizes over-fetching or under-fetching of data.
In a microservices architecture, what role does an API Gateway typically play?
- Facilitating communication between microservices
- Handling user authentication
- Managing database transactions
- Serving as a central monitoring tool
In a microservices architecture, an API Gateway acts as a central entry point for managing communication between microservices. It handles tasks such as routing, load balancing, and authentication, facilitating seamless communication between different services.
For APIs with a large number of input parameters, Equivalence Partitioning helps in reducing the test cases by focusing on _________.
- Specific input values
- Input value ranges
- Random input values
- All input values
Equivalence Partitioning is a testing technique where input data is divided into groups, or partitions, to reduce the number of test cases. In the context of APIs with many parameters, using input value ranges (Option b) allows us to cover different scenarios without testing each individual value, thus optimizing test case count.
Considering a scenario where an API undergoes frequent changes, what is a key challenge in maintaining the relevance and accuracy of automated tests?
- Ensuring backward compatibility with older API versions
- Handling increased testing time due to frequent changes
- Identifying and managing obsolete test cases effectively
- Updating test scripts promptly after each API change
In a scenario with frequent API changes, identifying and managing obsolete test cases is a key challenge. This involves regularly reviewing and updating test scripts to ensure they reflect the current API behavior, preventing outdated tests from providing inaccurate results.
_________ testing is essential for validating the interactions between different system modules, which is not the focus of unit testing.
- End-to-end
- Performance
- Regression
- Security
End-to-end testing validates the complete flow of a system, including interactions between different modules. This is crucial for ensuring that all components work together seamlessly, addressing concerns that are beyond the scope of unit testing.
When deprecating an API, it's essential to provide a(n) _________ for users to transition smoothly.
- Deprecated Handler
- Deprecated Notice
- Migration Guide
- Obsolete Warning
When deprecating an API, providing a Migration Guide is crucial. It includes detailed instructions, examples, and recommendations for users to transition smoothly to newer versions without disruptions. This ensures a seamless and informed migration process.
What is the significance of monitoring and logging in CI/CD pipelines with respect to API testing?
- Debugging Code Issues in Production
- Enhancing Code Readability and Maintainability
- Ensuring Compliance with Coding Standards
- Identifying Bottlenecks and Performance Issues
Monitoring and logging in CI/CD pipelines help identify issues early, allowing for quick resolution and improved reliability of API tests in production.
In Agile, API testing should align with the principle of _________ to maintain a sustainable pace of development.
- Continuous Integration
- Incremental development
- Just-In-Time Testing
- Test-driven development
Aligning API testing with Continuous Integration in Agile ensures that testing is an integral part of the development process. It promotes early detection of issues, facilitates rapid feedback, and contributes to a sustainable pace of development by automating the testing process within the development workflow.
