Magento 2 Testing course

Increase your Magento 2 code quality by writing powerful tests

Increase your Magento 2 code quality by writing powerful tests

Whenever you have business critical code in a live environment, like with a webshop, it is vital to make sure that bugs don't end up in production. Even more important, you don't want bugs to occur twice. Testing is the key. However, to get started with testing, you will first of all need a bit guidance. Second, you also need to get used to the right flow. This training helps you to get into the habit of writing unit tests, integration tests and functional tests.

background

We gave you MageTestFest

In 2018, we organized MageTestFest for the first time - in Amersfoort, The Netherlands. Room to 180 developers, focused entirely on Magento testing, with big names like Sebastian Bergmann and Mathias Verraes. In 2019, we did it again - in Florence, Italy. And maybe, maybe, one day, we'll be back.

Requirements

Requirements

  • Magento 2 experience
  • Knowledge of Magento 2 OOP
  • Experience with PHP OOP

These are the options we give you

At your place or ours?

Everyone learns at her/his own pace. We provide both in-house training and public training throughout Europe - whatever suits your team best. When 3 or more developers are attending, a custom training is often more economical. Contact us for more details.

You'll get courseware

Every workshop is accompanied with official Yireo coursematerial. Attendees are sent a digital version of this material after the training. It contains slides, comments and references. Additionally, our GitHub repos contain numerous more code samples.

Online classrooms

Online trainings are also our training: Via Zoom or Google Hangout sessions, our teacher is able to connect with your team. The benefit here is that the team is able to connect from various places itself as well, timeframes are more flexible. Afterwards, a video recording will be shared with all attendees for reference.

Frequently Asked Questions

There is a minimum number of attendees listed. What does this mean?

When this course is organized in the form of a classroom-training, it is only held if there is a minimum number of attendees. This number is usually 4 but sometimes we bring this down to 2 or 3. This minimum number simply means that if a class is not "full", either you get a refund or your ticket is transferred to another date. With On-Demand courses (video courses), this number is not applicable.

Do you have any PPP discount available?

Yes, we do have a PPP (Purchasing Power Parity) discount available. Just enter `PPP` as a coupon code and the discount will be applied to your cart. We are using the Big Mac Index to recalculate prices. Note that - when ordering for a specific PPP rate - the country that you're entering in your billing address needs to match the exact country that you are visiting from (in other words: your IP needs to match the country you say you're from).
