Designing a Test Strategy for Serverless Applications

Serverless applications are cloud-native, highly distributed, event-driven, primarily asynchronous systems, typically composed of a mixture of business logic and managed infrastructure.

These attributes are all desirable when building and operating modern software applications that must be scalable, resilient and highly-available.

However, the test strategies and tools engineering teams applied to more traditional client-server applications are no longer fit-for-purpose.

It’s time to rethink the test pyramid, TDD and coverage. It’s time to move beyond pull requests, ephemeral environments, end-to-end tests.

This talk will explore how modern DevOps practices like, continuous delivery, observability and infrastructure-as-code can shape a serverless test strategy.

We will also look at techniques teams can use to design a test strategy to suit their own serverless workloads.
