easy api tests code example

Example 1: api testing approach

Write suitable test cases for the APIs and use testing techniques 
like exploratory testing, boundary value analysis, positive and negative 
testing for understanding the functionality.

• Verify the calls with combination of two or more value added parameters.
• Define the scope and basic functionality of the API program.
• Define the accurate input parameters.
• Test case execution and comparison of the results with expected results.
• Determining API behavior under conditions like the connection with files,
etc.

- There are different types of output observed of an API also:

The main consideration is returning correct results under any type of 
conditions. Mainly, the output or results observed of an API are divided 
into three sections as follows:
• Returning the result status values as ‘Pass’ or ‘Fail’.
• Result as data or any specific information.
• An event where the call to any API function will initiate the call to 
another API function

Example 2: what to test in api

Request Payload has
ENDPOINT (Specific URL where we send our requests to a certain web service. )
METHOD (Get•Post•Put•Patch•Delete)
HEADERS(Represents the metadata of request
or response. Like basically we can verify
the object type we are sending etc  )
PARAMETERS(Parameters are to specifiying 
even more about the request we are sending 
like what specific resources needs to be returned etc.)
BODY(Body is where we sent or received the request we made)
For the repsonse 
Basically we are checking response body
to verify if request matches with response.
In the response we are verifying
(body, status code, header, response time,
 test structure of json against the given jsonSchema)
