[Xposed Framework Modules] rodken:
A/B testing of ADB Commads can be theorized as a randomized experiment using two or more variants of the same ADB (A and B). Variant A is the original and variant B through n each contain at least one element that is modified from the original. Before you can test, you might need something to test on.

There is also Multivariate testing is where you test more than one type of change at a time, looking for the impact of each change as well as potential synergies between the changes.

This thread is quite useful and is not exclusive to just one type of device.

Please read, proof-read and read a third time because some ADB Commands might not be sound and just, e.g., if you use Facebook, you can skip those commands.

These can be applied from your phone itself using Terminal ( recommend Termux app ) in which case "adb shell" won't be necessary.
