DSU

Introduction In a previous blog post, I delved into the use of Robot Framework for testing dynamic software updates. Although it worked reasonably well, a more sensible approach is to leverage tools readily available within the Erlang ecosystem. Consequently, this post will delve into the use of Common Test for testing dynamic software updates. Dynamic software updates Dynamic software update (DSU) refers to the process of updating parts of a program without halting its execution....

Introduction Dynamic software updates Dynamic software update (DSU) refers to the process of updating parts of a program without halting its execution. It enables running programs to be patched on-the-fly to add features or fix bugs. This capability is particularly crucial for applications that must consistently deliver reliable results. Examples of systems requiring dynamic software include: Banking applications Air traffic control systems Telecommunication systems Databases However, ensuring the correctness of a dynamic software update is challenging and complex....
