如何使用rpec在Rails測試環境中加載seed.rb？

Question

我有以下seeds.rb文件：

State.create  [ 
  {:name => "Alabama", :abbreviation => "AL" }, 
  {:name => "Alaska", :abbreviation => "AK" }, 
  {:name => "Arizona", :abbreviation => "AZ" }, 
  {:name => "Arkansas", :abbreviation => "AR" }, 
  {:name => "California", :abbreviation => "CA" }, 
  {:name => "Colorado", :abbreviation => "CO" }, 
  {:name => "Connecticut", :abbreviation => "CT" }, 
  {:name => "Delaware", :abbreviation => "DE" }, 
  {:name => "District Of Columbia", :abbreviation => "DC" }, 
  {:name => "Florida", :abbreviation => "FL" }, 
  {:name => "Georgia", :abbreviation => "GA" }, 
  {:name => "Hawaii", :abbreviation => "HI" }, 
  {:name => "Idaho", :abbreviation => "ID" }, 
  {:name => "Illinois", :abbreviation => "IL" }, 
  {:name => "Indiana", :abbreviation => "IN" }, 
  {:name => "Iowa", :abbreviation => "IA" }, 
  {:name => "Kansas", :abbreviation => "KS" }, 
  {:name => "Kentucky", :abbreviation => "KY" }, 
  {:name => "Louisiana", :abbreviation => "LA" }, 
  {:name => "Maine", :abbreviation => "ME" }, 
  {:name => "Maryland", :abbreviation => "MD" }, 
  {:name => "Massachusetts", :abbreviation => "MA" }, 
  {:name => "Michigan", :abbreviation => "MI" }, 
  {:name => "Minnesota", :abbreviation => "MN" }, 
  {:name => "Mississippi", :abbreviation => "MS" }, 
  {:name => "Missouri", :abbreviation => "MO" }, 
  {:name => "Montana", :abbreviation => "MT" }, 
  {:name => "Nebraska", :abbreviation => "NE" }, 
  {:name => "Nevada", :abbreviation => "NV" }, 
  {:name => "New Hampshire", :abbreviation => "NH" }, 
  {:name => "New Jersey", :abbreviation => "NJ" }, 
  {:name => "New Mexico", :abbreviation => "NM" }, 
  {:name => "New York", :abbreviation => "NY" }, 
  {:name => "North Carolina", :abbreviation => "NC" }, 
  {:name => "North Dakota", :abbreviation => "ND" }, 
  {:name => "Ohio", :abbreviation => "OH" }, 
  {:name => "Oklahoma", :abbreviation => "OK" }, 
  {:name => "Oregon", :abbreviation => "OR" }, 
  {:name => "Pennsylvania", :abbreviation => "PA" }, 
  {:name => "Rhode Island", :abbreviation => "RI" }, 
  {:name => "South Carolina", :abbreviation => "SC" }, 
  {:name => "South Dakota", :abbreviation => "SD" }, 
  {:name => "Tennessee", :abbreviation => "TN" }, 
  {:name => "Texas", :abbreviation => "TX" }, 
  {:name => "Utah", :abbreviation => "UT" }, 
  {:name => "Vermont", :abbreviation => "VT" }, 
  {:name => "Virginia", :abbreviation => "VA" }, 
  {:name => "Washington", :abbreviation => "WA" }, 
  {:name => "West Virginia", :abbreviation => "WV" }, 
  {:name => "Wisconsin", :abbreviation => "WI" }, 
  {:name => "Wyoming", :abbreviation => "WY"}
]

我可以使用rake db:seed命令將數據播種到開發環境中，但我對如何在測試環境中執行此操作感到困惑。 我正在使用rspec和rake test:prepare命令，但這只是設置一個空數據庫。

有沒有辦法在運行rake test:prepare時將數據只播種到測試環境中一次rake test:prepare ？

Answer 1

如果您只想在測試環境中運行rake db:seed ，則可以運行以下命令：

rake RAILS_ENV=test db:seed

實際上，您可以使用RAILS_ENV選項傳遞任何rails環境

Answer 2

我能夠添加......

load "#{Rails.root}/db/seeds.rb"

到我的spec / spec_helper.rb文件，每次運行測試時都會運行我的種子文件。

Answer 3

把它放在你的spec_helper中：

Rails.application.load_seed
