RESTful Services

Our main motive will be to learn

·      What is Rest?

·      Why to use Rest??

·      What we do with Rest???

Connecting your machine to a web services or web server

Now What is web services, it is nothing but the dynamic server that provide you the information or data according to the need.

Web Server can also be thought as bunch of functions that always return some or the other value in json or xml format depending upon the parameter.

API is the process through which our device,local machine connect with the web server and we specify our requirement and in accordingly, we get a data.

Basically in REST API, we do basic CRUD operation on Resource.

·      Create-POST

·      Read-GET

·      Update-PUT

·      Delete-DELETE

REST is nothing but Representation of resource i.e data depending on the Request……

The Representation of resource will always be of two types……

·      JSON

·      XML

Now the url in REST api will always be made of three things.

If we skip any of the single thing, then it will be diffcult for us to handle the info

REST API endpoint url+API method+parameter

REST API endpoint url is the pointer which act as address of place where all the method are kept

Method is the unique function where a respective functionality is placed

Parameter is the thing that is needed to take the input.

Application Programming Interface is used everywhere.

Whether it is flight booking, stock market, mutual funds, weather detail, hotel detail and etc

So API is used everywhere and especially in Travel Transport and Hospitality i.e. TTH domain, it is must to have API implementation and it through testing is required.

API testing makes the code more reliable of the API

API testing occur at very initial level, level even when GUI is not created and application as a whole is not prepared.

When the development team has created the API, it deploy the API to server and tester can test the API with or without inputs.

These days, in AGILE world, we can’t wait for whole application to be developed.

Also, at the end GUI testing doesn’t cover all the things that need to be tested.

GUI testing doesn’t do the testing to that level at which API testing is done

API testing mainly test the business layer of the application.
It never get concerned with the look and feel of UI.It will always focus on the logic and output that particular functionality produces by giving the desired input
