Writing Test Driven Apps with http4k

TOPIC Testing HTTP services can be a painful and challenging process for developers: tests are often slow running, involve complicated (or coupled) setup, rely on unreliable third party dependencies, or deal with complicated outputs.

In this talk, we demonstrate how the http4k library leverages its “Server as a Function” roots to enable writing apps which can be test-driven at all levels of the Testing Pyramid, using a set of tools derived from decades of experience testing backend applications to make many of the above issues go away.
