API testing is integration testing
of API's which checks the functionality , performance & security aspects of API's.
As GUI test is difficult to
maintain and requires a considerable amount of period, API has evolved as
primary testing of application logic.
API to be tested are those which
are developed by development team or third party API's which we would consume
in our project.
API testing involves:
- Calling the API
with different parameter values
- API boundary
performed by API i.e. updating database, calling other API
Popular API which are used are REST
implement in JSON format, which we will be looking during the course. Rest has
become most popular because it is light
and easy to maintain.
Rest-assured is library developed
by Jaway which is best open source library specially designed to automated Rest
API. It also supports
XML and JSON Request/Responses.
No need of any tool when you need
to automate API, simple coding skills will let you perfect automation of API,
will be taught during the course.
- Request can be
easily prepared and send over internet
- Assertions in
- Clean code
which is easy to be maintained
