Rspec 无法在现有 RailsApp 中执行简单规范

Question

我在 rails v4.0.9 中有现有的 RailsApp

我的团队使用一些 gem 开发并在文件夹 initializers 中配置多个文件

我需要使用 Rspec 构建测试框架，这是我的 Gemfile：

group :development, :test do
  gem "rspec-rails", "~> 3.1.0"
  gem "factory_girl_rails", "~> 4.4.1" , :require => false
end

group :test do
  gem "faker", "~> 1.4.3"
  gem "capybara", "~> 2.4.3"
  gem "database_cleaner", "~> 1.3.0"
  gem "launchy", "~> 2.4.2"
  gem "selenium-webdriver", "~> 2.43.0"
end

我刚刚尝试构建模型规范，模型名称是 cart，首先我输入了非常简单的规范，只是为了确保 Rspec 正常运行：

require 'rails_helper'

describe Cart do
    it "has a valid factory for Cart"
end

在spec/factories/cart.rb：

FactoryGirl.define do
    factory :cart do
        user_id { Faker::Number.number(3) }
    end
end

当我输入控制台 rspec spec/models/cart_spec.rb 时：

config/initializers/cassandra.rb:25:in `initialize': undefined method `[]' for nil:NilClass (NoMethodError)
    from config/initializers/cassandra.rb:59:in `new'
    from config/initializers/cassandra.rb:59:in `block in <top (required)>'
    from lib/cassandra_utils/connector.rb:13:in `configure'
    from config/initializers/cassandra.rb:58:in `<top (required)>'
    from .rvm/gems/ruby-2.1.5/gems/activesupport-4.0.9/lib/active_support/dependencies.rb:223:in `load'
    from .rvm/gems/ruby-2.1.5/gems/activesupport-4.0.9/lib/active_support/dependencies.rb:223:in `block in load'
    from .rvm/gems/ruby-2.1.5/gems/activesupport-4.0.9/lib/active_support/dependencies.rb:214:in `load_dependency'
    from .rvm/gems/ruby-2.1.5/gems/activesupport-4.0.9/lib/active_support/dependencies.rb:223:in `load'

我该如何解决这个问题？

谢谢

ENV['IC_CONTACT_POINTS']

返回 falsey 值，因此 cassandra_config['IC_CONTACT_POINTS'] 被评估。

cassandra_config 是 nil。修改它，你会没事的。
