advantages of api testing code example

Example 1: advantages of api

1-We can start testing process 
EARLY and the more bugs we
catch in API level testing,
the less bugs we will see on UI.
API level of application is
developed before the UI part.

2- API tests enable highly 
integrable tests, which is 
particularly useful if you
want to perform functional
GUI tests after API testing. 

3-In API testing,
data is exchanged
using XML or JSON.

4- Time Effective:
API testing usually is less time consuming
than functional GUI testing.

Example 2: benefits of api testing

We can start testing process EARLY and the more bugs we
catch in API level testing, the less bugs we will see on UI. API
level of application is developed before the UI part.

Test for Core Functionality: API testing provides access to
the application without a user interface.

Time Effective: API testing usually is less time consuming
than functional GUI testing. The web elements in GUI testing
must be polled, which makes the testing process slower

Language-Independent: In API testing, data is exchanged
using XML or JSON. These transfer modes are completely
language-independent

Easy Integration with GUI: API tests enable highly integrable
tests, which is particularly useful if you want to perform
functional GUI tests after API testing.
