Use Faker::Lorem.word with caution

Flaky tests are tests that randomly fail. I think it was Oriol who linked an awesome post about them.

As you can imagine, I have flaky tests... and I want to resolve it. Reading some literature about it I've found this:

There are only 249 values in Faker::Lorem::Word collection, so there is a non-trivial chance of collision.

Combined with a uniqueness validation, this could be fatal. The solution is to use it with Factory Bot Sequences:

Instead of:

factory :user do
  name { Faker::Lorem.word }
end

Use:

factory :user do
  sequence(:name) { |n| "#{Faker::Lorem.word}-#{n}" }
end
