Don’t reduce dispatcher testing to an afterthought
Frankly speaking, dispatcher usually does not receive much attention when it comes to testing. In most cases configuration updates get inspected only on the go without any regression tests being triggered alongside.
Neglected dispatcher may lead to application issues that often slip through unnoticed across lower level environments and surface right after production deployment.
Overlooked dispatcher testing doesn’t come out of nowhere - it’s neither straightforward nor easy to implement a reliable test suite for it. Moreover, dispatcher is often not verbose enough and all its surroundings would have to be mocked out to test it in isolation.
This talk will describe various techniques (man-in-the-middle proxying, mocking strategies, configuration tricks, CI/CD pipeline examples, etc) to let you test and promote your dispatcher config with confidence.
