Why Is API Testing Different

Key Points

Presentation Abstract

This presentation describes the challenges unique to the testing of Application Programming Interfaces (APIs). We isolate and explain three problems/difficulties commonly encountered while testing APIs.

These problems are:
1)Parameter Selection
2)Parameter Combination
3)Call Sequencing

We then provide solutions to these challenges and through examples show how to build effective API test automation.
