REST APIs typically use _______ for data transfer, making them lightweight.

  • CSV
  • HTML
  • JSON
  • XML
REST APIs commonly use JSON (JavaScript Object Notation) for data transfer. JSON is lightweight, easy to read, and well-supported in modern web development. It allows for efficient communication between clients and servers in a RESTful architecture.

_________ in Postman refers to the feature that enables...

  • Automation
  • Monitors
  • Newman
  • Pre-request Scripts
"Pre-request Scripts" in Postman refer to the feature that enables automated testing of APIs through scripts. These scripts run before the actual request is sent, allowing you to set up conditions or modify parameters dynamically.

In API deprecation, what is the role of versioning control?

  • Ensures backward compatibility
  • Facilitates parallel API development
  • Improves API security
  • Manages the release cycle
Versioning control is crucial in API deprecation to facilitate parallel development. By maintaining different versions, developers can introduce changes gradually without disrupting existing clients. This allows for a smoother transition when deprecating older versions.

Which metric is commonly used to evaluate the performance of an API during testing?

  • Code Complexity
  • Code Duplication
  • Lines of Code
  • Response Time
Response time is a crucial metric in API performance testing. It measures the time taken by an API to respond to a request, reflecting its efficiency and speed. Monitoring response time helps ensure that the API meets performance expectations and delivers a satisfactory user experience. It is a key indicator of the overall health and performance of the API under different conditions.

In advanced API testing, automation scripts are used to simulate _________ to test the API's behavior under stress.

  • Concurrent user interactions
  • Large data payloads
  • Slow internet connections
  • Unexpected errors
Simulating concurrent user interactions is a key aspect of stress testing in API automation, helping assess the API's performance under heavy loads.

What role does data caching play in enhancing API performance for large data sets?

  • Causes data corruption
  • Enhances performance
  • Increases data transfer time
  • Slows down performance
Data caching in APIs improves performance by storing frequently accessed data, reducing the need for repeated data retrieval from the server.

Which type of API testing focuses on the behavior of the API under specific conditions?

  • Load Testing
  • Performance Testing
  • Scenario Testing
  • Security Testing
Scenario testing involves assessing the API's behavior under specific conditions or scenarios. This type of testing helps identify how the API responds to various inputs and situations.

For testing the resilience of an application, mock APIs can be used to simulate _________ conditions.

  • Ideal
  • Normal
  • Real-world
  • Stressful
Mock APIs provide a way to simulate real-world conditions, allowing developers to test how an application responds to various scenarios. Using mock APIs, one can replicate the actual conditions an application may encounter in production, including stress and load conditions.

In an Agile environment, how often should developers and testers meet to discuss progress and issues?

  • Daily
  • Monthly
  • Only during Sprint Planning
  • Weekly
In Agile, frequent collaboration is essential. Daily meetings between developers and testers help discuss progress, issues, and any necessary adjustments. This ensures continuous communication and adaptability throughout the Agile development process.

In API automation, what is the significance of using environment variables?

  • Enhances script security by hiding sensitive information
  • Facilitates script portability across different environments
  • Improves script execution speed through optimized variable storage
  • Simplifies the debugging process by isolating environment-specific issues
Using environment variables in API automation is significant for facilitating script portability across different environments. By storing configuration details, such as URLs or authentication tokens, in environment variables, scripts become more adaptable to various testing environments. This practice streamlines the process of executing scripts in different setups, enhancing the overall efficiency and maintainability of API automation tests.
