David Denton, Ivan Sanchez Writing test driven apps with http4k

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 3rd party dependencies, or deal with complicated outputs. In this talk, the speakers will demonstrate how the http4k library leverages its Server as a Function roots to enable writing apps which can be testdriven 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. This talk is about Kotlin HTTP server technologies and how to test them to overcome problems (slow, flakey tests, lack of reuse, The audience gets an intro to the Server as a Function concept and http4k, but also can take away a lot of knowledge about how to apply the solutions to those problems in a unique and original way.
