AppleScript vs. JavaScript vs. Radamsa vs. SlimerJS Comparison Chart

AppleScript is a scripting language created by Apple. It allows users to directly control scriptable Macintosh applications, as well as parts of macOS itself. You can create scripts, and sets of written instructions, to automate repetitive tasks, combine features from multiple scriptable applications, and create complex workflows. AppleScript 2.0 can use scripts developed for any version of AppleScript from 1.1 through 1.10.7, any scripting addition created for AppleScript 1.5 or later for macOS, and any scriptable application for Mac OS v7.1 or later. A scriptable application is one that can be controlled by a script. For AppleScript, that means being responsive to inter-application messages, called Apple events, sent when a script command targets the application. AppleScript itself provides a very small number of commands, but it provides a framework into which you can plug many task-specific commands, those provided by scriptable applications and scriptable parts of macOS.

Radamsa is a test case generator for robustness testing or fuzzer. It is typically used to test how well a program can withstand malformed and potentially malicious inputs. It works by reading sample files of valid data and generating interestingly different outputs from them. The main selling points of Radamsa are that it has already found a slew of bugs in programs that actually matter, it is easily scriptable, and, easy to get up and running. Fuzzing is one of the techniques to find unexpected behavior in programs. The idea is simply to subject the program to various kinds of inputs and see what happens. There are two parts to this process: getting the various kinds of inputs and how to see what happens. Radamsa is a solution to the first part, and the second part is typically a short shell script. Testers usually have a more or less vague idea of what should not happen, and they try to find out if this is so.
