Unit Testing in AEM (thinking loud)


Unit testing is an art – an art that doesn’t need to be confined to boundaries drawn decades back. AEM has made unit testing even more tough with its evolution and people are still trying to find the best fit aka what will work for them.

This article tries to explain some of my thoughts and what ways i would like to tackle unit testing in AEM and it’s not traditional in any ways.

I dont think there is one right way of doing it and this is just a beginning….

High availability design


Of course, eventually with many fixes over time you will eradicate a lot of cases that led to failures but it would have taken you so long and the reputation that the brand holds do dear is already damaged. You can chose to design for High Availability or you can chose to be just like Indian Railways – always delayed and always cancelled – a perspective that will i don’t think will ever be fixed no matter what they do.

AEM Development Workflow – Part 3 (Coding Old School)


The journey was nothing but painful all along the way. It took me 5 hours to do what should have been a few minutes job. The Site developer had the code up and running in a HTML file in a browser and all I had to do was to make it work “as is” within CQ. It seemed like the Force of Nature were working against me and everything I did, had a problem in it. I finally got it up and running (the designs done match off as is still), but it was excruciating pain.

AEM Development Workflow – Part 2 (finding the problem)


The AEM workflow problem is not really an inefficiency in the handover of HTMLs to CQ developers but how we should have been writing the code to begin with. We start here by seeing where the problem starts and how the code has been written. Unfortunately, we do see the OOTB Code in AEM as provided by Adobe itself are not coded to solve the problem. When I speak with Adobe they make it clear that these are reference sites and are to used as “Self-learning” but little did they know at the time that people will take this a practice and convert this into a culture.

Tip: Using AEM Developer Tools for Eclipse


This is a key step, and unless you get all those dependencies and if your project is brand new your project will not compile. If you are using an existing project it may just work if you have added those dependencies, but from experience as we dont compile JSPs those dependencies will not kick in. The code still works on CQ server because those dependencies are available at runtime.

Thick Clients and CMS


Can a technology like Angular be used in the world of a CMS to solve the process problems where it just takes too long to get HTMLs from Site Developers into CQ’s templates and that too with a degree of quality that we are expected to deliver. This article lays down the foundation of what the challenges are and how it has started to impact our day to day life. The answer is not that simple, but at the looks of it, it seems we are using a technology to solve for a problem which is actually a people or a process problem. You can of course introduce a new component in the mix, but I still believe until people are ready to change, this new component wont do shit.

Caching Architecture (Adobe AEM) – Part 1


If you ever have designed or want to design a platform/site that needs to support some steep non-functional requirements like 1Billion hits, then you have to rever to using cache as a key part of the framework. How cache as we have known it back in the days is not longer just plugging in a library and start writing to it. There is a lot more to it when we talk in context of a Digital Media platform and how you deal with very high loads. This article will talk about principles that will help you design for
– Performance: Caching is a pattern that we employ to increase the overall performance the application by storing the (processed) data in a store that is a) closest to the consumer of the data and b) is accessible quickly
– Scalability: In cases when we need to make the same data-set available to various consumers of the system, caching as a pattern makes it possible for us to scale the systems much better. Caching as we discussed earlier allows us to have processed data which takes away the need to run the same processing time and again which facilitates scalability
– Availability: Building on similar principles as of scalability, caching allows us to put in place data in areas where systems/components can survive outages be it network or other components. While it may lead to surfacing stale data at points, the systems are still available to the end users.
