What is API testing for beginners?

API (application programming interface) testing is a sort of programming testing that performs check
legitimately at the API level. It is a piece of joining testing that decides if the APIs meet the analyzers' desires
for usefulness, unwavering quality, execution, and security. Not at all like UI testing, API testing is performed at t
he message layer without GUI.


Here are the fundamental tips that you have to know for API testing: 


1. Comprehend API requirements


Prior to testing your APIs, you have to address these inquiries to completely comprehend the API's
prerequisites: 
Knowing the reason for the API will set a firm establishment for you to well set up your test information for info
and yield. This progression likewise encourages you to characterize the check approach. For instance, for some
APIs, you will confirm the reactions against the database; and for some others, it is smarter to check the
reactions against different APIs.


2. Determine the API yield status 


The most widely recognized API yield you have to confirm in API testing is the reaction status code. 


Confirming if the reaction code equivalents to 200 or not to choose whether an API testing is passed or fizzled is
well-known to new API analyzers. This is anything but an off-base confirmation. In any case, it doesn't mirror all
test situations of the API.


3.  Focus on small functional APIs 


In a testing venture, there is in every case some APIs that are basic with just a couple of information sources,
for example, login API, get token API, wellbeing check API, and so forth. Notwithstanding, these APIs are vital
and are considered as the "entryway" to enter further APIs. Concentrating on these APIs before the others will
guarantee that the API servers, condition, and validation work appropriately.


4. Compose API endpoints 


A testing task may have a couple or even many APIs for testing. We exceptionally propose that you sort out
them into classifications for better test the executives. It makes one additional stride yet will altogether assist
you with making test situations with high inclusion and mix.


5. Chose a reasonable automation tool


A further advance to use the mechanization ability of API testing is picking the most appropriate apparatus or a
lot of reasonable devices from several choices in the market.
