Http client test code#

Let’s consider a class that performs HTTP requests: class M圜lass When a method performs only one request, it’s very convenient to use, but when the class performs many request and you want to make assertions on the requests it becomes a bit more complex. It already embeds a MockHttpClient and MockResponse to ease testing. Symfony/HttpClient is a powerful component to perform HTTP(s) requests.

Tasty tests (for me, anyhow) start with some Mocha and some Chai! With that singular addition, you can expect all kinds of things! But First, Mix In Some Chai(.js) SuperTest extends that basic (and wonderfully obvious) API with a singular.

Here's what SuperAgent code to send a POST request looks like (cribbing from their opening example): requestĪlert('yay got ' + JSON.stringify(res.body)) SuperTest is built on the fabulous Node and browser HTTP client called SuperAgent. So I ended up testing my test server via a thing called SuperTest. I needed to be sure curl and the browsers would get the correct output from my API, and I needed the ability to test it from 'across the Web' where the various intermediaries (proxies, coffee shops, etc.) might interfere. However, things quickly got bothersome as testing the internal Python API was only part of the puzzle. I sat down to write some Python, receive some HTTP requests, and return some JSON. To test the Web Annotation Protocol, I started by implementing it within the Web Platform Tests system frequently used to test browser-side JavaScript APIs specified by various W3C Working Groups. Unlike the code you're writing now, this protocol started its life as a specification and, as it has grown and changed, has been implemented to make sure the spec can do what it says it can. Recently, I've been working on testing the Web Annotation Protocol which was designed as part of the Web Annotation Working Group at the W3C. Making sure it's dependable and does what it promises is invaluable to giving others a solid foundation to build upon. External developers - including the browser-client team - depend on this surface to build their code on top of it. HTTP APIs are the web-level 'surface area' of your application. That outbound API needs at least as much love and attention (if not more!) than the internal, code-level APIs you write for yourself and friends. Congrats! However, at that layer, you are only writing tests for yourself, your teammates, or others consuming your code-level interfaces.īut what about your web-level interface? Your HTTP API is the interface you give others who depend on your code without even being able to see it (like the good ol', pre-open source days. You probably even write unit tests and measure the code coverage of your business logic.
