Testing with headless browser (Zombie.js + Jasmine)

I was planning to post this article a few weeks ago, but today I finally finished the examples and I can't wait to share it. We all know that the testing is a big part of our daily tasks and we should use every existing tool to make our lives easier. I really like test driven development and once I found the concept of the headless browsing I started to think that we can automate every single aspect of the testing. In this post I'll show you how to use Nodejs to test a simple php site.

Extending Jasmine (BDD framework for testing)

Don't get me wrong, Jasmine is a wonderful framework. I'm using it for testing JavaScript in both places - front-end (in browser) and back-end (Nodejs). However, the client side has some disadvantages, which I just fixed. I hope that someday these changes will be moved to the official version (or at least I'll make a pull request very soon).

Unit test your client-side JavaScript

I don’t think that we have to discuss the importance of having tests. That’s not something that we add to the project in addition. That’s something that the project is based on. And because testing is so important we have bunch of tools in our disposal. We all know (I hope) how to test our back-end code. However, once we move to the front-end is a bit different. At the moment we are working on a big single page application and testing is one of our main focuses. In this article you will see how to unit test our client-side JavaScript.

JavaScript's reduce could be really helpful

I love using functions like map, filter or reduce. They are an important part of my arsenal and I simply can’t stop using them. Today I had to solve an interesting problem and I ended up using reduce.

Miss Piggy - a test runner for Puppeteer

These days I did (again) a bunch of changes in Google tag manager. This time however was more of a refactoring exercise. So, I had to prove that the tags that were placed before the refactoring exist after the refactoring. And what we programmers do in such cases - we write tests.

Using web dev skills to test web dev skills

Last year or so, I worked on a platform where I would publish video courses. The first one is on web fundamentals (in Bulgarian), and it's almost ready. You can check it out here. But this article is not about that. It's about a platform feature I built - an in-house validator to exercise the gained HTML, CSS, and JavaScript knowledge. After each lesson, I give a task to the students, and they can work on it right in the browser. The small application became an inspiration for another project - iloveweb.dev. So, I decided to share how the validation works.
