Test Data Libraries for Elixir
The factory library ExMachina created by Thoughbot uses function names and generates an atom used to call factories. For example:

How to write test cases for databse related functions
The well known FactoryBot (FactoryGirl) from rails has a pretty good equivalent in Phoenix as ExMachina (https://github.com/thoughtbot/ex_machina) and does the job really well (thoughtbot is a pretty good and stable contributor too, so a nice Omakase plug-in!)

Test Data Libraries for Elixir
Faker generates sample data that looks realistic but is fake. So, instead of using a sequence like those provided by ExMachina or ExZample, we can use Faker to generate false but genuine-looking data:

How to write test cases for databse related functions
Generating the data structs for the views can be automated using libraries like Faker and Blacksmith - and honestly writing your own generators is a fun and easy exercise in really understanding your data and how it's manipulated (which I would argue is critical to writing clean software).
- Succinct naming
