The use of _________ in API testing tools aids in simulating external system components during test automation.
- Dummy Modules
- Mock Objects
- Placeholder Entities
- Simulated Entities
Mock objects play a crucial role in API testing by simulating external system components. They help create controlled environments for testing, allowing developers to isolate and evaluate specific functionalities without relying on actual external systems.
When testing a newly released version of an API, how does updated documentation assist in identifying changes impacting existing test cases?
- Explains the history of the API
- Guides in identifying breaking changes and adapting test cases
- Helps testers understand changes in API endpoints
- Provides insights into potential security vulnerabilities
Updated documentation is crucial for identifying breaking changes that may impact existing test cases. It outlines modifications in endpoints, payload, or behavior, enabling testers to adapt and validate the application against the updated API. This helps maintain test accuracy and coverage.
When testing APIs with large data sets, focusing on ___________ is essential to prevent data corruption and loss.
- Authentication
- Authorization
- Data Integrity
- Encryption
Data integrity is crucial in API testing to prevent data corruption and loss. It ensures that the data remains accurate, consistent, and unaltered during various operations, enhancing the reliability of the API.
In the context of microservices, API versioning becomes challenging due to _________.
- Dependency Chains
- Distributed Data
- High Coupling
- Inter-Service Communication
Microservices pose challenges to API versioning due to issues like inter-service communication and high coupling, making it important to carefully plan versioning strategies.
In GraphQL, what is the purpose of an introspection query?
- It executes mutations
- It fetches all available queries
- It provides information about the schema
- It retrieves user data
An introspection query in GraphQL is used to get information about the schema itself. It helps developers understand the types, queries, and mutations available in the API. It is not intended for user data retrieval or mutation execution.
What is the benefit of involving testers in the code review process?
- Enhancing Code Quality
- Improving Test Efficiency
- Minimizing Bug Reports
- Reducing Development Time
Involving testers in the code review process brings diverse perspectives, helping identify defects and potential improvements early. Testers can focus on aspects related to testability, ensuring the code meets testing requirements, ultimately enhancing overall code quality.
How does versioning in RESTful APIs differ from that in GraphQL APIs?
- REST uses Header versioning, GraphQL uses Query versioning
- REST uses Query versioning, GraphQL uses Header versioning
- REST uses Schema Stitching, GraphQL uses URI versioning
- REST uses URI versioning, GraphQL uses Schema Stitching
The key difference lies in versioning approach. REST typically uses Query versioning, where version information is specified in the API request itself, while GraphQL often relies on Header versioning, where version details are included in the request headers. Understanding these distinctions is crucial for developers working with both RESTful and GraphQL APIs.
In a scenario where an API used by numerous external clients is being deprecated, what is the most critical factor to ensure a smooth transition?
- Communication and Documentation
- Gradual Transition Period with Clear Communication
- Immediate Discontinuation without Communication
- Rapid Deprecation without Notice
When deprecating an API, ensuring a gradual transition period with clear communication is crucial. This allows clients to adapt, update, and migrate smoothly, minimizing disruption and maintaining positive relationships. Immediate discontinuation can lead to chaos, and rapid deprecation without notice may create confusion. Effective communication is key to a successful transition.
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.
