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.

Faced with a scenario where an API's response time increases under high load, what would be your first step to identify the bottleneck?

  • Analyzing network traffic
  • Checking database queries
  • Examining CPU and memory usage
  • Reviewing server logs
In scenarios of high load, CPU and memory usage are critical indicators of bottleneck. Analyzing these metrics can help identify resource constraints and optimize performance.

How does the integration of AI and ML in API testing tools enhance the test automation process?

  • Dynamic Test Scripting
  • Intelligent Test Data Generation
  • Predictive Analysis
  • Real-time Monitoring
The integration of AI and ML in API testing tools enhances the test automation process by enabling intelligent test data generation. AI and ML algorithms can analyze application behavior, user patterns, and historical data to generate realistic and diverse test data. This ensures more comprehensive test coverage and helps identify potential issues that may not be apparent with static test data. Predictive analysis allows the tool to anticipate potential areas of failure and prioritize test cases accordingly. While dynamic test scripting and real-time monitoring are valuable, they do not capture the breadth of benefits offered by AI and ML integration.

What is the importance of testing for Cross-Site Request Forgery (CSRF) in APIs?

  • Enhancing user authentication
  • Ensuring data confidentiality
  • Optimizing database performance
  • Protecting against unauthorized actions
Cross-Site Request Forgery (CSRF) in APIs involves protecting against unauthorized actions. CSRF attacks attempt to perform malicious actions on behalf of an authenticated user without their consent. Testing for CSRF helps ensure the security of API actions and protects users from unintended operations.

For effective monitoring, it is essential to track the _________ time of API responses in production.

  • Execution
  • Latency
  • Processing
  • Response
Monitoring the latency of API responses is crucial for identifying and addressing performance issues. Latency measures the time it takes for an API request to be processed and receive a response. By tracking latency, you can pinpoint bottlenecks and optimize your API for better performance.

Which level of software testing does API testing typically fall under?

  • Acceptance Testing
  • Integration Testing
  • System Testing
  • Unit Testing
API testing typically falls under the category of Integration Testing. It involves verifying that the different components or modules of a software application work together as expected when integrated. This ensures the seamless communication and interaction between various parts of the system, especially focusing on API endpoints.

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.
