How is the PATCH HTTP method different from PUT in terms of resource modification?
- It allows partial updates to a resource.
- It is only used for read operations.
- It is specific to deleting resources.
- It is used for complete resource replacement.
The PATCH method is used to apply partial modifications to a resource, while PUT is typically used for complete resource replacement. PATCH allows more granular updates without affecting the entire resource.
When designing a REST API, which HTTP method would you choose to ensure idempotence for updating existing resources?
- DELETE
- PATCH
- POST
- PUT
The PUT method should be chosen to ensure idempotence for updating existing resources in a REST API. PUT is used to update or create a resource at a specific URI, and sending the same request multiple times has the same effect as sending it once. PATCH is used for partial updates, POST for creating resources, and DELETE for deleting resources.
Which tool is commonly used for mocking APIs during development?
- JIRA API Mock
- Postman
- Swagger
- WireMock
WireMock is a popular tool for mocking APIs during development. It provides a simple and flexible way to simulate API responses, enabling efficient testing and development without relying on real API endpoints.
What role does contract testing play in microservices architecture?
- Ensures that microservices adhere to agreed-upon contracts
- Has no significant role in microservices architecture
- Validates the functionality of microservices
- Verifies microservices against a central database
Contract testing plays a crucial role in microservices architecture by ensuring that each microservice adheres to its agreed-upon contracts. This helps maintain consistency and reliability in communication between microservices, promoting a robust architecture.
In analyzing a security breach through API logs, what key factor should be scrutinized to prevent future incidents?
- Analyzing payload content for vulnerabilities
- Examining DNS resolution for suspicious activity
- Monitoring server response codes
- Reviewing access logs for unusual patterns
Scrutinizing payload content for vulnerabilities is crucial when analyzing API logs for a security breach. By examining the data exchanged, one can identify potential security loopholes or injection attacks. Understanding the payload content allows for targeted security measures to be implemented, preventing similar incidents in the future.
How does GraphQL handle versioning in comparison to REST APIs?
- Automatically through the schema
- By adding version information to the HTTP headers
- Through URL versioning
- Using query parameters
GraphQL handles versioning through the schema, avoiding the need for version information in URLs or headers. This is a key difference compared to REST APIs, where versioning might be managed through parameters or headers.
How should an organization handle client dependencies when deprecating an API?
- Ignore client dependencies as it's the client's responsibility to adapt.
- Inform clients with sufficient notice, provide alternatives, and offer support during the transition.
- Offer no support and let clients handle the deprecation independently.
- Suddenly deprecate the API without informing clients to speed up the transition.
When deprecating an API, it's crucial to communicate effectively with clients, giving them ample notice, providing alternative solutions, and offering support during the transition. Abruptly deprecating an API without proper communication can lead to disruptions and dissatisfaction among users.
How does an Agile team balance the need for comprehensive API testing with the time constraints of a sprint?
- Extend the sprint duration to accommodate testing
- Prioritize critical tests and conduct risk-based testing
- Sacrifice testing quality to meet sprint deadlines
- Skip testing and rely on user feedback
Agile teams navigate time constraints by prioritizing testing efforts. Conducting risk-based testing allows teams to focus on critical aspects, ensuring essential functionalities are thoroughly tested within the sprint's timeframe. This strategy aligns with Agile principles of adaptability and responsiveness to deliver valuable increments.
In a cross-functional team, the integration of _________ tools helps streamline the workflow between development and testing.
- Code Review
- Continuous Integration
- Unit Testing
- Version Control
Continuous Integration tools automate the process of integrating code changes, enabling frequent and automated builds. This integration streamlines the workflow between development and testing teams, ensuring that changes are tested promptly and efficiently.
What is the significance of Contract Testing in API development?
- Contract Testing ensures that APIs adhere to legal contracts.
- Contract Testing is only relevant for small-scale projects.
- Contract Testing verifies that different parts of an API work well together.
- It focuses on checking the compatibility and agreements between different services interacting through APIs.
