TL;DR

In the above image, you can see the Elixir Espec testing framework in action. Framework (in test setup code) creates testing HTTP connection (this is conn structure). Check is expect function, where we check, does conn resp_body (HTML page) contains project structure name. The project is created using insert_project() the helper, where project.name is set using the Elixir Faker library. We use Faker’s name function that returns a random name.

That test randomly failed, and I know that problem was with the project name attribute.
