API Testing tutorials 1 - Idempotency, Safe, Cache and Versioning Concept

We are going to understand some of the important Concepts in rest API for sample example I have added a screenshot from Postman which is a popular API testing.

Concept in rest API

we are going to cover four important concepts like:

• Idempotency
• save
• cache 
• versioning

Let us understand the first concept idempotency:

Idempotent methods can be called multiple times with same input, and it produces same result.

example if we are having a get request and we are hitting it multiple times then we are going to get same result so what we can say get is idempotent.

I have talked about these concepts in detail in this video:

In Part 1 of the video we are going to discuss:

- What is GraphQL 

- Difference between GraphQL and Rest API 

- Advantage of GraphQL 

- How queries are fetched in GraphQL 

- Software Testing API Testing

 

A query language for your API

GraphQL is a query language for APIs and a runtime for fulfilling those queries with your existing data. GraphQL provides a complete and understandable description of the data in your API, gives clients the power to ask for exactly what they need and nothing more, makes it easier to evolve APIs over time, and enables powerful developer tools.
