Biggest sources of flaky tests (from our experience)

FactoryGirl

When using FactoryGirl to create records in tests, it is necessary to be aware that you are usually creating a lot more records than is obvious in the code. While this is usually harmless aside from slowing down tests, it is capable of creating some mind boggling flakiness. Some scenarios where this is probable are tests that count the number of records, tests that are expecting a certain record and assume that only it exists. Improperly set model level validations can also contribute to this.

Blizzard Software Engineering Reading

by Jay Baxter (circa 2009)

Associate developer

"This list is for people who want to become Associate Software Engineers at Blizzard. An associate should have skills at the level indicated by these books. Note that this is almost completely focused on C++ programming. This list is incomplete. I need a book on how to become a professional. I've listed several books that give examples of professional behavior, but not one on the actual training."

Running redis using upstart on Ubuntu

I've been trying to understand how to setup systems from the ground up on Ubuntu. I just installed redis onto the box and here's how I did it and some things to look out for.

To install:

class User < ActiveRecord::Base
  def forms
    Form.where(:company => company)
  end

  def find_form(id)
    forms.find(id)
  end
end

class User < ActiveRecord::Base
  def find_form(id)
    company.forms.find(id)
  end
end

  factory.attachment(:sample, "public/samples/sample.doc", "application/msword")
