To ensure seamless data exchange, _________ must be thoroughly tested when integrating a third-party API.
- Authentication
- Authorization
- Data Encryption
- Error Handling
In third-party API integration, it's crucial to test for error handling to ensure that the system can gracefully manage API limitations or failures. This includes handling unexpected responses or errors from the API and preventing potential data loss or system instability.
To maintain data consistency in microservices, _________ strategies are often employed.
- CQRS (Command Query Responsibility Segregation)
- Event Sourcing
- Load Balancing
- Saga
To maintain data consistency in microservices, Saga strategies are often employed. The Saga pattern helps manage distributed transactions by breaking them into a series of smaller, independent steps or compensating transactions. It ensures that the system remains consistent even when multiple microservices are involved in a transaction, and failures occur.
_________ testing in GraphQL is essential to verify that the API enforces proper access control to its data and operations.
- Authorization
- Performance
- Regression
- Unit
Authorization testing is crucial in GraphQL to ensure proper access control to data and operations. This involves checking if only authorized users can perform specific actions, helping to secure the API against unauthorized access.
In a scenario where an API must handle sensitive data, what OAuth strategies would you employ to maximize security?
- Choose OAuth 2.0 Implicit Flow
- Implement OAuth 2.0 Authorization Code Flow with PKCE
- Use OAuth 2.0 Resource Owner Password Credentials (ROPC) Flow
- Utilize OAuth 2.0 Client Credentials Flow
For handling sensitive data, the Authorization Code Flow with PKCE is recommended as it ensures secure exchange of authorization codes, reducing the risk of exposing sensitive information.
In a situation where an API dealing with large data sets experiences performance degradation, what would be your initial step in troubleshooting?
- Analyze API logs and identify bottlenecks
- Implement a content delivery network (CDN)
- Increase server resources such as CPU and RAM
- Optimize network bandwidth for data transmission
Analyzing API logs helps identify potential bottlenecks and performance issues. Increasing server resources, optimizing network bandwidth, and implementing CDNs are valid strategies but may not be the first step in troubleshooting. Understanding the specific issues from logs is crucial before taking corrective actions.
What is a common challenge faced when integrating API test automation into a continuous integration pipeline?
- Inadequate Test Data Management
- Lack of API Documentation
- Limited Test Case Reusability
- Overlapping Test Environments
Integrating API test automation into a continuous integration pipeline can be challenging due to the lack of proper API documentation. Without clear documentation, understanding and writing test cases become difficult.
_________ is a key tool in managing the deprecation of APIs by informing users of upcoming changes.
- Semantic Versioning
- Git Version Control
- Deprecation Warning
- API Documentation
The correct option is "c) Deprecation Warning." Deprecation warnings serve as a crucial tool for notifying users about upcoming changes in APIs, allowing them to adapt and make necessary adjustments to their code. These warnings help in smooth transitions and reduce unexpected disruptions.
Which protocol is primarily used for communication in REST APIs?
- FTP
- HTTP
- TCP
- UDP
REST APIs commonly use the HTTP protocol for communication. HTTP is a stateless protocol that allows communication between clients and servers, making it suitable for RESTful services.
In Agile teams, who is typically responsible for conducting API testing?
- Developers
- Product Owners
- QA/Testers
- Scrum Masters
In Agile teams, QA/Testers are typically responsible for conducting API testing. Developers focus on coding, Product Owners on defining user stories, and Scrum Masters on facilitating the Agile process. QA/Testers ensure the quality of the software by testing various aspects, including API functionality, performance, and security.
When testing APIs with numerical inputs, applying Boundary Value Analysis to _________ and _________ values can uncover hidden bugs.
- Minimum, Maximum
- Odd, Even
- Positive, Negative
- Zero, Non-zero
When dealing with numerical inputs in API testing, applying Boundary Value Analysis to the minimum and maximum values is crucial. This approach helps reveal hidden bugs that may arise at the edges of the accepted input range. By testing both the lower and upper bounds, testers can ensure the reliability and correctness of the API's numerical handling.
