如何使用rpec在Rails测试环境中加载seed.rb？
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命令将数据播种到开发环境中，但我对如何在测试环境中执行此操作感到困惑。 我正在使用rspec和rake test:prepare命令，但这只是设置一个空数据库。
有没有办法在运行rake test:prepare时将数据只播种到测试环境中一次rake test:prepare ？
如果您只想在测试环境中运行rake db:seed ，则可以运行以下命令：
rake RAILS_ENV=test db:seed
实际上，您可以使用RAILS_ENV选项传递任何rails环境
我能够添加……
load "#{Rails.root}/db/seeds.rb"
到我的spec / spec_helper.rb文件，这会在每次运行测试时运行我的种子文件。
