How does OAuth 2.0 differ from OAuth 1.0 in terms of API security?
- OAuth 1.0 uses signatures over tokens
- OAuth 1.0 uses tokens over signatures
- OAuth 2.0 uses signatures over tokens
- OAuth 2.0 uses tokens over signatures
OAuth 2.0 introduced a shift from signatures to tokens for better scalability and simplicity. It relies on access tokens rather than cryptographic signatures for security.
To assess the stability and reliability of an API, _________ testing is performed to determine how the API behaves under sustained use.
- Functional
- Integration
- Load
- Unit
Load testing is essential for evaluating the performance of an API under various levels of load. It helps identify bottlenecks and weaknesses in the system when subjected to sustained use and heavy loads.
In a CI/CD pipeline, API tests are often executed after the _________ stage.
- Build
- Deployment
- Planning
- Testing
In a CI/CD pipeline, API tests are typically executed after the Deployment stage. This is because, during the Deployment stage, the application is deployed to a testing environment, allowing for comprehensive API testing to ensure the proper integration of components. API tests at this stage help catch integration issues before they progress further in the pipeline.
RESTful APIs typically use _________ for data exchange, while SOAP APIs use _________.
- CSV
- JSON
- XML
- YAML
RESTful APIs commonly use JSON for data exchange, providing a lightweight and easy-to-read format. SOAP APIs, on the other hand, typically use XML for data exchange, which is more rigid and structured.
In complex test environments, what is a common challenge related to dependency management?
- Difficulty in version control of dependencies
- Incompatibility issues with different versions of dependencies
- Lack of documentation for dependencies
- Security vulnerabilities in dependencies
In complex test environments, managing dependencies becomes challenging due to potential incompatibility issues arising from different versions of dependencies. This can lead to runtime errors and affect the reliability of the testing environment.
For an API that needs to support third-party clients, what considerations are important when choosing an OAuth flow?
- Opt for OAuth 2.0 Authorization Code Flow with PKCE for a balance between security and usability
- Prefer OAuth 2.0 Client Credentials Flow for simplicity and efficiency
- Select OAuth 2.0 Authorization Code Flow for enhanced security
- Use OAuth 2.0 Implicit Flow for better user experience
Supporting third-party clients requires balancing security and usability, making OAuth 2.0 Authorization Code Flow with PKCE a suitable choice for enhanced security without compromising user experience.
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.
Faced with the need to test APIs with varying response times, what characteristic of an automation tool would be most effective?
- Code Reusability
- Data-Driven Testing
- Headless Browser Support
- Synchronization Mechanism
In situations where APIs exhibit varying response times, a crucial characteristic of an automation tool is its Synchronization Mechanism. This feature ensures that the automation script waits for the expected response, allowing the tool to handle dynamic response times effectively. It prevents false positives or negatives in test results by synchronizing actions with the application's state.
