4. INTRODUCTION
The acronym API stands for Application Programming Interface. APIs are programming
interfaces that connect applications to each other, a database, or a messaging system.
API test development and execution is the most important grey-box functional testing a
tester performs if the application(s) shares data, messaging, and relies on the input and
output of various API endpoints. API testing is performed to ensure API endpoints and
data sharing functions work as expected. API testing ensures connecting data feeds
are sending the data expected as well as how, when, and where expected. API testing
guards against data corruption in transit or sudden failures in database or endpoint
connectivity. API testing ensures your application functions perform as intended for
applications designed for web or mobile environments.
Testing APIs is an essential skill for the modern-day software tester. Mobile and web
applications use data continuously and share it amongst applications making the
software tester role more complex. Testing the API connections for an application is a
critical skill in today’s professional software tester job market.
