In the realm of
serverless computing,
testing emerges as a cornerstone for ensuring the
reliability and
performance of
applications built upon this paradigm. With serverless applications structured as a collection of functions operating in managed environments, effective testing
strategies become imperative for identifying and addressing potential issues early in the development lifecycle. In this article, we delve into the comprehensive landscape of testing serverless applications, exploring key approaches such as unit testing, integration testing, and end-to-end testing. Additionally, we discuss essential strategies for mocking external services and dependencies, empowering developers to validate the functionality, reliability, and
scalability of their serverless applications with confidence.
