What is mean by API testing?
Application Programming InterfaceDefinition: API (Application Programming Interface) testing is a type of software testing that aims to determine whether the APIs that are developed meet expectations when it comes to functionality, performance, reliability and security for an application.
What is REST API example?
A REST API is a way for two computer systems to communicate over HTTP in a similar way to web browsers and servers. Sharing data between two or more systems has always been a fundamental requirement of software development. For example, consider buying motor insurance.
Which tool is best for API testing?

When should we do API testing?
API testing involves testing the application programming interfaces (APIs) directly and as part of integration testing to determine if they meet expectations for functionality, reliability, performance, and security. Since APIs lack a GUI, API testing is performed at the message layer.
What is REST API and how does it work?
APIs specify the way information passed across platforms is structured so that applications can exchange data and information. REST is an API architecture style. It stands for representational state transfer. REST specifies how data is presented to a client in a format that is convenient for the client.
Where is REST API used?
This is because REST is the most logical, efficient and widespread standard in the creation of APIs for Internet services. To give a simple definition, REST is any interface between systems using HTTP to obtain data and generate operations on those data in all possible formats, such as XML and JSON.
How do you test REST API?
For each API request, the test would need to take the following actions:Verify correct HTTP status code. … Verify response payload. … Verify response headers. … Verify correct application state. … Verify basic performance sanity.
Is API testing easy?
Therefore, API testing task is easy to be underestimated. … It is because the returned data have similar structures, but not the same in a testing project. It will be difficult to decide if you should verify the JSON/XML data key by key, or using object mapping to leverage the power of programming language.
What makes a good REST API?
Good REST APIs: are well-documented and reliable. use HTTP verbs as Fielding originally defined. support X-HTTP-METHOD-Override to accommodate picky proxies.
Why do we test API?
And API testing allows the tester to make requests that might not be allowed through the UI, which is crucial for exposing potential security flaws in an application. Because changes in software happen at such a rapid pace today, it’s important to have tests that provide fast feedback for developers and testers.
What are the types of API testing?

Validation testing is one of the last steps in the development process, but it is one of the more important tests that can be run. … Functional Testing. … UI Testing. … Load Testing. … Runtime/Error Detection. … Security Testing. … Penetration Testing. … Fuzz Testing.More items…•
What is the difference between API and Web services?
There you have it: an API is an interface that allows you to build on the data and functionality of another application, while a web service is a network-based resource that fulfills a specific task. Yes, there’s overlap between the two: all web services are APIs, but not all APIs are web services.

How does REST API work?
REST determines how the API looks like. It stands for “Representational State Transfer”. It is a set of rules that developers follow when they create their API. One of these rules states that you should be able to get a piece of data (called a resource) when you link to a specific URL.
What is API example?
An application-programming interface (API) is a set of programming instructions and standards for accessing a Web-based software application or Web tool. … For example, Amazon.com released its API so that Web site developers could more easily access Amazon’s product information.
What is difference between REST API and RESTful API?
What’s the difference between a REST API and a RESTful one? … The short answer is that REST stands for Representational State Transfer. It’s an architectural pattern for creating web services. A RESTful service is one that implements that pattern.
