What is the difference between API testing and rest API testing?

As an experienced tutor registered on UrbanPro.com specializing in API & Web Service Testing Training, I understand the importance of clarifying the distinction between API testing and REST API testing. Let's explore the key differences to help you make an informed decision when seeking the best online coaching.

API Testing

• Definition: API testing, or Application Programming Interface testing, involves validating the functionality, reliability, performance, and security of an application's APIs.
• Scope: Encompasses testing different types of APIs, including SOAP, REST, and other web services.
• Approach: Focuses on the broader spectrum of API testing without emphasizing a specific protocol.
• Use Cases: Applicable to a variety of API types, making it versatile for testing diverse applications.

REST API Testing

• Definition: REST API testing specifically targets APIs adhering to the principles of Representational State Transfer (REST).
• Scope: Concentrates on testing APIs that follow RESTful architecture.
• Approach: Emphasizes testing methods, status codes, and the stateless nature of RESTful APIs.
• Use Cases: Ideal for applications that rely on RESTful APIs, such as web and mobile applications utilizing HTTP as a communication protocol.

Key Differences

1. Protocol Emphasis:

   • API Testing: Encompasses testing various API types, not limited to any specific protocol.
   • REST API Testing: Specifically focuses on APIs following REST principles and utilizing HTTP.

2. Scope of Testing:

   • API Testing: Broad in scope, applicable to SOAP, REST, and other web service APIs.
   • REST API Testing: Narrower focus, concentrating on RESTful APIs and their specific characteristics.

3. Testing Methods:

   • API Testing: Covers a wide range of testing methods applicable to different API types.
   • REST API Testing: Emphasizes testing methods, status codes, and statelessness characteristic of RESTful APIs.

Why Choose Specialized Coaching?
