Current topic in my working life is refactoring. I try to find methods and patterns on how to design programs better just from the start. And I try to find ways to solve general refactoring issues. I was searching for sample code that was not mine. ...
Often, a seemingly small and simple task is actually a little bigger, the more and deeper you think of it, you sure have experienced this as well. Here's an example: Task: Select something from the last 24 hours (e.g. sales orders (VBAK) maybe to se...

The claim is that nobody ever does Test Driven Development in real ABAP life so I have volunteered to give it a go in my day job. Unbreakable I have never ever done TDD outside blogs. It works really well, but experimental programs are not real, ...
So where do we begin? All the way at the beginning of time! 13.8 billion years ago, the universe was created in what is indubiously known as The Big Bang. Well maybe we don't have to go that far back. Let's just start with where this HTML thing came...
At this stage people were always going to either love or hate the idea of unit testing. As the course progresses the subject matter gets more complicated and thus more and more divisive. This week’s subject was “Test Isolation”. Isolation Ward A...

I was going to comment on this blog https://blogs.sap.com/2018/04/05/opensap-abap-unit-testing-course-getting-lost-in-the-weeds/ but decided instead to write my own in response! There's a Russian card game call Durak. A great game, in many ways quit...
Having somehow made it to week 4 of the openSAP course about ABAP Unit Testing it becomes rather apparent that this is way above my still rather rudimentary grasp of ABAP OO - see my earlier post about those particular struggles. Heck, I'm still not ...
The dawn of mobile platforms ushered in a new era of user interaction with computer applications or computer programs. Yes, these software are being loosely referred to as "computer applications/programs," stemming from the stereotype : whether the a...

This blog summarizes some facts and rules regarding database objects managed by the AS ABAP. That should have been done long before. But recently it became more and more important, because there is an increasing tendency to access ABAP-managed databa...
There are only a few posts about CL_ABAP_TESTDOUBLE. I didn't find it so trivial to use, even tricky sometimes. Even Google returns only 14 results for "CL_ABAP_TESTDOUBLE". The most interesting information I could find is Prajul Meyana's ABAP Test D...

This week SAP picked a particularly thick wall to bang their heads against by advocating “pair programming” as an aid to unit testing and a generally good thing. Dilbert Pair Programming The first week in this course covered unit testing, which h...
What's it all about? This is just a short blog for me to share a solution to a common problem when you're dealing with large volumes of data, where you can't read it all at once from the database. An ancient curse upon these cursors! The old way of d...
As mentioned in my recent blog post about the openSAP ABAP Unit Testing course, and as the title of this post makes clear, I have a hard time wrapping my head around anything ABAP-OO (or should I say ABAP - oh, oh?): I've been in programming since 19...
