### Description

The app contains an example of the Golden Master testing technique.

Below an article quote:

>  In computer programming, a **characterization test (also known as Golden Master Testing)** is a means to describe

(characterize) the actual behavior of an existing piece of software, and therefore protect existing behavior of

legacy code against unintended changes via automated testing. This term was coined by **Michael Feathers**...... When

creating a characterization test, one must observe what outputs occur for a given set of inputs. Given an

observation that the legacy code gives a certain output based on given inputs, then a test can be written that

asserts that the output of the legacy code matches the observed result for the given inputs.
