A small example of an implementation of a small domain model. The example
consists of three files. The first file HandlingSensitiveData contains the implementation of
the domain model. The second file HandlingSensitiveDataTest contains a PHPUnit test suite
demonstrating the handling of sensitive data.
The files contain comments about what is happening.
The PHPUnit tests can be run by changing to this directory and running:
$ phpunit .
PHPUnit 5.6.2 by Sebastian Bergmann.
