api testing tool code example

Example 1: api request tools

Tools to send API request
Postman -- Desktop client tool
Curl -- Command line client tool
RestAssured -- Java client library
SoapUI -- Desktop client tool

A lot of API documentation provide curl
command for example when we run the request and
Postman can easily import curl command without you
manually typing the whole part of the request.

Example 2: 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
