This class can be used to figure what to test next when testing many factors.

It uses the multi-armed bandit algorithm to test several groups of factors and iteratively propose a new option to be tested as eventual the best.

The class can retrieve and store the values for the groups of factors to be tested using functions that can be overridden by sub-classes which can store and retrieve the values in any type of storage like files and databases.

When you need to test an application that has many factors influencing its behavior, it may be hard or even impossible to test it in all possible situations.

You need to decide which factors should be tested with greater priority to provide a basic set of relevant tests. However, it may still be hard to decide which factors are more important to test first.

This PHP class implements the multi-armed bandit algorithm to optimize testing processes by proposing successive sets of factors to test in each iteration.
