Suddenly, every test in our Rails 4 app fails - ruby-on-rails-4

Question

My co-workers tell me these tests pass when they run them. But I just checked the code out from Bitbucket, and for me, the tests fail. I made sure that my machine has the same version as my co-workers:
Rails 4.2.4
Ruby 2.2.3
rake, version 10.4.2
After some pain with nokogiri, I was able to get "bundle install" to run.
But if I do this:
bin/rake test
Every test fails:
27 runs, 0 assertions, 0 failures, 27 errors, 0 skips
with an error that looks like this:
6) Error:
ProfilesControllerTest#test_#update:
NoMethodError: undefined method `type' for nil:NilClass
Error:
ProfilesControllerTest#test_#update:
NoMethodError: undefined method `each' for nil:NilClass
Here is an example of some failing code:
require 'test_helper'
class ProfilesControllerTest < ActionController::TestCase
test '#update' do
profile = profiles(:no_address_profile)
login(profile)
VCR.use_cassette('essex_street_ny') do
patch :update, profile: {address: '15 Essex street, New York, NY, USA', zipcode: '10002'}
end
updated_profile = Profile.find_by_user_id(profile.user_id)
assert_equal '15 Essex street, New York, NY, USA', updated_profile.address
assert_equal '10002', updated_profile.zipcode
assert_redirected_to root_path
end
test '#update with only zipcode' do
profile = profiles(:no_address_profile)
login(profile)
VCR.use_cassette('only_10002_zipcode') do
patch :update, profile: {zipcode: '10002'}
end
updated_profile = Profile.find_by_user_id(profile.user_id)
assert_equal '10002', updated_profile.zipcode
assert_redirected_to root_path
end
def login(profile)
session[:user_id] = profile.user_id
end
end
So what is really happening here?
UPDATE:
If I do :
rake db:fixtures:load
I get:
rake aborted!
NoMethodError: undefined method `type' for nil:NilClass

It sounds like you need to run migrations in your test environment. You can do that like so:
rake db:migrate RAILS_ENV=test
