In software engineering a concern is something that is responsible for a single 'side' of the functionality. This principle states that a given problem involves different kinds of concerns, which should be identified and separated to cope with. In short, separation of concerns is a guiding principal in software development centered on the idea that programs should have distinct sections, with each section being responsible for its own concern. The following list shows how to test each code module from our extended example: User interface and interactions: Use an Android UI instrumentation test. Full support for multi-dimensional separation of concerns opens the door to on-demand remodularization, allowing a developer to choose at any time the best modularization, based on any or all of the concerns, for the development task at hand.

Separation of Concerns (SoC) - is the process of breaking a computer program into distinct features that overlap in functionality as little as possible. design should provide two-dimensional separation of concerns [6] and a facility to make the two dimensions transferable. For example, program proving becomes much more feasible when details of sequencing and memory management are absent from the program. Every element of a software application - a component, a layer,a package,a class or a method should have one concern and implement it well. Horizontal separation of concerns is typically realized. A strange defect showed up, which would be almost impossible to reproduce back on our developer machine. We consequently pursue it at a level of abstraction much higher than programming, as done for example with aspect-oriented programming.
