factory_girl_rails/factory_bot_rails RuntimeError: can't modify frozen Array - Gherkin factory_bot_rails

Having the same problem after changing to FactoryBot from FactoryGirl and factory_girl_rails to factory_bot_rails

NOTE: if you get this test error, the very first test error will give you more details on what's breaking.

In my case, just changed my factory field from password 123456 to password { 123456 } solved.

@nezirz there were some deprecations in factorybot 4.11, so you will want to upgrade to that version and deal with the warnings before upgrading to factorybot 5.0.

gem install rubocop-rspec and then rubocop --require rubocop-rspec --only FactoryBot/AttributeDefinedStatically --auto-correct

worked for me

@joshuaclayton nothing too useful, I'm afraid.

Here it is, in case it helps:

An error occurred while loading .<spec_path>_spec.rb.
Failure/Error: require File.expand_path("../../config/environment", __FILE__)

This is on Rails 5.2.1 and Ruby 2.5.1

I had the same problem when tried to upgrade fromrails 5.2.0 to 5.2.2.1using bundle update rails command, its also updated many other gems one of them was factorybot from 4.10.0 to 5.0.2 so solution was to downgrade to 4.10.0 by specifying the version number for factorybot to gem "factory_bot_rails", "~> 4.10.0"

@joshuaclayton - Fast response! There was a few, but we've since narrowed it down to this gem being bumped - eg; we took this upgrade out and everything was fine.

Failure/Error: require File.expand_path("../../config/environment", __FILE__)

FrozenError:
  can't modify frozen Array

# ./config/environment.rb:17:in `<top (required)>'
# ./spec/spec_helper.rb:14:in `<top (required)>'
# ./spec/<our_spec_file>_spec.rb:1:in `<top (required)>'

respectively:
-> Rails.application.initialize!
-> require File.expand_path("../../config/environment", __FILE__)
-> require 'spec_helper'

(Edit: tag)

Sorted! The problem was that the grep command given in the blog post to Replace All Constant References didn't actually change all the instances of FactoryGirl in the code base. After we found that and did a global change with Atom it all works fine. This is an example diff of one of the files missed by the grep that I had to manually change:

git diff spec/factories/activation_code.rb
diff --git a/spec/factories/activation_code.rb b/spec/factories/activation_code.rb
index 493f7942..8c727cb5 100644
--- a/spec/factories/activation_code.rb
+++ b/spec/factories/activation_code.rb
@@ -1,4 +1,4 @@
-FactoryGirl.define do
+FactoryBot.define do
   factory :activation_code do
     code { Faker::Lorem.characters(6) }
     code_valid { true }

Something like this grep looks like it fixes it: grep -rl 'FactoryGirl' ./ | xargs sed -i '' 's/FactoryGirl/FactoryBot/g'
