no commentsThe best way to avoid regressions and get fast feedback during development is automated testing. Especially if you’re testing manually by speaking to your voice app. The logic of your voice app is implemented in a webhook called a fulfillment. Since fulfillments are regular JSON APIs they are tested using existing technology.
May 8th, 2019Whenever I give or facilitate an EventStorming training or workshop people always ask me, what is inside your suitcase? What are the essential items I need to do a successful EventStorming? Most importantly what do I need to buy! So in this post, I will give you the EventStorming tools that are in my flight case and where you can buy it!
May 6th, 2019At some point in your application’s lifecycle, there might come a time when you need to start scaling your data storage. If you are storing media files or other blobs that have no relations between them, you can easily add storage capacity to solve the problem. For (semi-)structured data in a database however, scaling is a whole different story. Simply adding database instances is not enough. You will need to reconsider the usage patterns and decide what solution solves the problem you have. If your database is hitting resource limits because it is accessed very frequently, adding an asynchronous read replica might be the way to go. If the size of the data is the issue and lookups become very slow, you might consider sharding your database.
April 30th, 2019Over recent years, a tool called EventStorming became one of the go-to techniques for Domain-Driven Design consultants to collaboratively explore complex business domains at customers. Since consultants travel a lot from company to company helping with their questions about approaching software delivery this poses a small 1st world problem; How can we still comfortably travel while still carrying the required equipment to do an EventStorming at the customer (without breaking our back or needing a personal fitness coach). This was exactly the conversation we, Maxime Sanglan-Charlier and Kenny Baas-Schwegler, had during DDD Europe 2019. In this post, Maxime and Kenny will share their quest in finding the perfect EventStorming backpack.
April 29th, 2019This blog is part of a series about comparing Cypress and TestCafé.
In part 1 (link) I introduced both of the frameworks with some examples of how they work, epic features and more.
In this part of the series, I will give you a straight-forward comparison of the 2 frameworks which hopefully will help you in your quest to find the best framework that suites your ambitions.

April 15th, 2019The asynchronous workflow pattern, also known as the publish-subscribe pattern, is an architecture pattern which is typically used to asynchronously perform resource intensive and time consuming tasks. To separate the request from the task itself we can use a queue where the sender puts messages that another service can pick up.
This pattern is a subset of the CQRS (Command-Query Responsibility Segregation) pattern. CQRS defines a clear separation of a command and query model [MF-CQRS], while the asynchronous workflow pattern only defines a command model without caring how the result of a command is being read.
April 12th, 2019In my whitepaper I wrote about different types of testing and what to consider when choosing a test automation strategy. More than a few readers asked how to put this advice into practice, and a good friend inspired me to write another blog post about it.
DevOps teams automate everything. When you’re getting started with test automation, it’s important to wonder why someone would want to automate tests. And what is testing, anyway? This article describes what testing is and what parts of that process can be automated. Fortunately, there’s no way test automation will eliminate manual testing; it will just make that process more efficient.
April 9th, 2019AWS recently announced the possibility to send control plane logs from their managed Kubernetes service (EKS) to CloudWatch. Amongst those logs are the API server audit events, which provide an important security trail regarding interactions with your EKS cluster
Sysdig Falco is an open-source CNCF project that is specifically designed to monitor the behavior of containers and applications. Besides monitoring container run-time behavior, it can also inspect the Kubernetes audit events for non-compliant interactions based on a predefined set of rules.
Wouldn’t it be nice if you could automatically monitor your EKS audit events with Falco? In this blog post we will show you how to make this work.
April 3rd, 2019At Xebia we focus on building the right thing the right way. To do so we need to continuously receive feedback on the quality of our code. As such, a testframework that supports our way of working is paramount to success.
In this article we will have a look at Cypress and TestCafé CLI.
