unit testing - Rails 4: Why do fixtures make this test fail? -

i have test below , if there fixtures model fails total_unapproved , new_total being equal instead of new_total being 1 less. if remove loading fixtures in test_helper.rb or comment them out runs expect.

here's class function sets approvals true. works.

def inviterequest.approve_invites(number)   inv_reqs = inviterequest.where("approved = ?", false).first(number)   inv_reqs.each |inv_req|     inv_req.approved = true     inv_req.save     inv_req.send_approved_email   end end 

here's test calls above function.

require 'test_helper'  class inviterequesttest < activesupport::testcase    test "class method approve_invites(number) should approve 'number' inviterequests"     # ensure there @ least 1 instance     inv_req = inviterequest.create(email: "hobojoe@test.com")      # set inviterequests.approved false     inviterequest.all.each {|r| r.approved = false; r.save}     total_unapproved = inviterequest.where("approved = ?", false).count     rails.logger.info "\nunapproved before: #{total_unapproved}"     inviterequest.approve_invites(1)     new_total = inviterequest.where("approved = ?", false).count     rails.logger.info "unapproved after: #{new_total}\n"      assert_equal total_unapproved - 1, new_total   end  end 

any idea why? i'm not using fixtures in other tests maybe someday.

my fixtures weren't valid , changing them fixed problem. i'm still not sure how things failing though. fixtures looked this:

one:   email: mystring  two:   email: mystring 

this fail uniqueness validation , not save i'm not sure why newly created model wouldn't have 'approved' set true , still saved since it's correct.

anyway, changing fixtures fixed things.

one:   email: someguy@example.com  two:   email: somegirl@example.com
