A library to generate boundary condition values for your tests

Boundary data faker

To properly test boundary conditions of your form / entity, you need to generate quite a lot of data, which exceeds boundary conditions / values., _(*1)

Say, you have User entity with 2 required fields name and email, and 1 optional, which is age., _(*2)

The validation rules are:
- name
    - 3-20 chars long
- email
    - 5-50 chars long
    - a regular expression
- age
    - numeric
    - greater then 18

In order to have all cases, which must throw an exception covered, you need to manually create quite a big amount of data: - ['name' => '']
- ['name' => '12']
- ['name' => 'a string, which length is more than 20 chars'] - ['email' => '']
- ['email' => '1234']
- ['email' => 'a string, which length is more than 50 chars'] - ['age' => 'string'] - ['age' => 0], _(*3)
