Announcing RSS Proxy 1.0 - Automated Feed Generator

tl;dr: rss-proxy transforms almost any website into a feed, just with one click. RSS is the glue code for an open and free internet. It helps you build your own network of sources. Unfortunately some websites don’t support it at all or not in a way to fill your need. This is where rss-proxy comes to play. It is a simple middleware that transforms HTML to a feed. The user will choose a suggested feed from a collection of feeds that exist in a website of interest....

End to End Testing - Before You Get Started

A lot of articles have been written on the topic end-to-end testing. I won’t cover the basics here. In this post I want to draw your attention to some questions, you should answer before you start even looking for a framework. And.. start slow! Here is my story: In my last job I inherited the task to write end-to-end tests, so it was somehow easy to get started. We were using protractor, angular was still hot in these days....

Kontor CLI (2017 - Present)

If you are like me and try to keep looking for interesting ideas and concepts, you will at some point reach a point of information and cognitive overload. The internet is full of distractions and its difficult to keep the focus for some time, even harder to stay focused on a topic for a longer period like weeks. I was looking for an automated way to keep following interesting people/sites archive them and while avoiding all the distractions Hence, I am implementing a little cli tool that handles web sources in a general way, which in most cases are pure RSS feeds, in the complex cases JSON or HTML corpora, that I have to map to a proper format....

Automate the UI-test Automation

Test automation especially ui test automation is like a huge jenga tower, everything is always about to collapse. How can we rely on them? Only run stable tests (stability) Keep the execution time low (performance) Only run the important tests for first feedback (performance) Loosly coupled with the code under test (maintenance) A test should have a maintainer that is required to fix it (maintenance) A failing test should express what functionality has been broken, ideally in a way even non-tech people can understand (maintenance) ...

Principles of Luhmann's Zettelkasten

Write (small) notes, using note sequences to develop an idea or topic Where possible or necessary (i.e., if an idea can be considered as “start” of a new note sequence, but does fit into the current linear argumentation), branch off a new idea-path Check if similar topic or “story line” has been written down elsewhere; if yes, add manual links / references Identify relevant notes that function as “starting” point and tag these notes (from Daniel Lüdecke [2] ) https://vimeo....

Perceptual Diff Testing

One goal of successful testing is decoupling the tests from the code under test, with the goal to reduce the need for maintenance of the test code, when changing the actual code. Perceptual Differences (pdiff) is one approach to achieve that goal. Enriched with protractor, its possible to compare screenshots within a flow. "...

Developer Dashboards

( I already had some thoughts on that topic ). Goal Get a better overview of future/pending/past work and keep it. “If you want a developer to do something, e.g. establish a high test coverage, make it easy with sane reasons” What? Pre-Deployment Feature Branches, consisting of PRs Build (Test) Reports Static Code Analysis (Report?) Build Status green/yellow/red Human Code Analysis (Code Reviews) Post-Deployment Monitoring Active (Alerts) Passive Configuration Feature Flags?...
