How to deal with test-debt

Albert Starreveld - October 17, 2019

A lack of automated tests slows a team down and makes it more complicated to release software. Especially, when you’re just getting started with continuous delivery, there is few test-automation, if any at all. Fixing it all in one go is too much work. So, how do you deal with that?

How to combine Behavior Driven Development and Scrum

Albert Starreveld - September 26, 2019

Going to production more often means less time to make sure new features don’t cause any trouble. Validating everything manually in a short amount of time seems impossible and prone to errors. Moving from waterfall to Scrum requires another approach: Functional tests that validate the software does what it’s supposed to do, automatically. That requires the process to change, too:

Configuring standard policies for all repositories in Azure Repos

Jesse Houwing - August 21, 2019

By default you can only configure policies on specific branches in Azure Repos. You access the policies through the Branch's [...] menu and set the policy from there. But if you're using a strict naming pattern for your branches (e.g. when using Release Flow or GitHub Flow), you may want to set a policy for all future Release Branches, or all Feature branches. Wouldn't it be nice if you could write these policies into law, that way you don't have to set them for every future branch.

Getting started with test-automation in your current project

Albert Starreveld - June 24, 2019

Releasing more often is easier said than done. The release frequency of a product depends on the time it takes to test it. Changing a line of code is easy. Testing that change is a lot more difficult. And it’s usually a bad idea to release untested software. Implementing test automation in an existing codebase can take serious effort. It does not only change the code, but it also changes the way of working. So where to get started?

The 5 unit testing guidelines

Albert Starreveld - June 24, 2019

A unit test is a small automated check. It checks a tiny bit of software. Unit tests can be written relatively easily and they run in a matter of milliseconds. In reality, unit tests are often far from small. They’re often hard to maintain and it’s hard to understand what the code that’s being tested was supposed to do when a test fails. As a result, unit testing becomes a costly exercise that slows down the team and the test-results doesn’t really prove much. These 5 guidelines help writing proper unit tests.

A simple, effective test automation strategy

Albert Starreveld - April 12, 2019

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.

Webservice Plan Scaling in Azure Machine Learning Studio

Rob Bos - February 27, 2019

I recently found that I had a web service plan running for my Machine Learning Studio (MLS) workspace in Azure. I was hosting some test webservices on it from a research session earlier on. The web service plan was not doing anything for me, but I did incur some costs running it. Since the default tier it picks during is already an S1, this can build up if you are paying the subscription yourself.

Sending Delivery information to VictorOps from Azure DevOps releases using Bash

Michiel van Oudheusden - September 27, 2018

When you are using an Incident Management alerting tool like Pagerduty or VictorOps, it might be beneficial to notice when your deployment system is performing an action. Like doing a release to your environment. Pretty useful to correlate with an incident coming in. VictorOps has an integration called Delivery Insights. Basically a specific endpoint where third-party tooling can send a specific payload to so it can record a release. VictorOps has GitHub integration, but their Azure DevOps (VSTS) integration is lacking. Luckily we can do this ourself.

Use Carter to create a simple HTTP API in ASPNET Core

Michiel van Oudheusden - September 26, 2018

Creating an HTTP API can be done in multiple ways, but if you are a .NET developer, you most likely will use the ASP.NET Web API framework. In previous versions, this was not always that obvious to use. The MVC framework and the Web API framework were actually two different systems. For example; action filters for one framework did not work for the other framework. With newer versions, this difference was solved by having one integrated system. However, there are other frameworks that allow you to do similar things. It is all a matter of taste what works best for you, your team and the project. In this post, Michiel will show you Carter.

As there is a lifetime on those tokens, we need to retrieve a new one each time we start a test. Luckily that is not too difficult in Runscope.
