In the ever-evolving world of API development, MuleSoft emerges as a key player, offering immense potential for robust and reliable integrations. Drawing from diverse projects and collaborations, I’ve identified common API testing challenges that transcend industries. Let’s explore these challenges, enriched with real-world examples, and then apply them to the specific context of an Online Banking API.

Addressing Common API Testing Challenges

Imagine an attempt to place an order with a negative quantity—neglecting such tests could expose vulnerabilities. This lesson underscores the importance of testing beyond the expected, ensuring resilience in the face of unconventional inputs.
