 Hi, I'm Kristoff Taylor, a senior engineer at Nurex. We're an Ember shop with a focus on sensitive medicine. We're most well known for selling birth control, STI testing, PrEP, and other sexual health services. We're currently rolling out a COVID-19 testing service. With such sensitive and important information that our software is dealing with, testing is very important to us. We've got a stack with Ember on the front end and Node on our back end. In service of our monolingual stack, we've decided to blaze a new trail and integrate the powerful Just-Expex library into our Mocha test runner and unify our front and back end testing. Just's testing framework has been gaining traction in the wider JavaScript world at a phenomenal pace. It provides some very powerful and deep partial object matching features that make testing complex JSON API data structures a breeze and straightforward to test. Just object matching syntax allows you to test for the general look and feel of an object without having to be exact in the ways that are irrelevant to the test at hand. CHI can achieve similar functionality with its extensive modifiers, but you lose the familiarity of the underlying object structure. Cure unit, meanwhile, is lacking in those convenience helpers to test for complex data relations. Just's-Expex library is a standalone assertion library that can be dropped into many test ecosystems and is easily extensible to add your own assertion helpers. As far as I know, we're the first ones to go all in and integrate Just's library into our Ember stack. If that sounds interesting to you, feel free to reach out to us to learn more about how we managed our integration. Thank you.
