rest apit testing code example

Example 1: how do you do positive api testing

How I do positive testing in api, 
	- I send valid path and query parameters, 
	- valid headers, 
	- valid request body to valid url and verify that 
	- response status code is correct and 
	- response body is as expected
    
How I do negative testing in api,
	- I send invalid request parameters
	- or invalid headers
	- or invalid request json body and verify 
    that response status code is not 200 
	- and response body contains error message 
    (for example there are 100 employees numbered
    from 1 to 100 I send 101 as a parameter and I
    should be able see 404 Not Found 
    The requested resource was not found.)

Example 2: what need to verify in api testing

We will verify the accuracy of the data
Will see the HTTP status code
We will see the response time
Error codes in case API returns any error
Authorization would be check
Non-Functional testing such as 
performance testing, security testing.
