ruby-on-rails - 如何在 Rails Capybara 测试中为几个 "scenarios"运行一次安装程序

Question

相关问题:how to run capybara commands once, then run some tests

如何设置 Capybara 测试以仅运行部分后台一次，并在那里为测试中的场景记录数据库。

请注意，我在测试之间使用 database_cleaner。是的，我有一些seed_tables，但我想要一个范围不是全局的，而是一个集成测试文件。

feature "some feature" do
background do
 # set up some records that don't change between scenarios

 # set up some records that do change between scenarios
end

scenario "scenario 1" do
  # run tests
end

scenario "scenario 2" do
  # run tests
end
end

这是我对 database_cleaner.rb 的设置:

RSpec.configure do |config|
  config.add_setting(:seed_tables)
  config.seed_tables = %w(global_options shoot_types)

  config.before(:suite) do
    DatabaseCleaner.clean_with(:truncation, except: config.seed_tables)
  end

  config.before(:each) do
    DatabaseCleaner.strategy = :transaction
  end

  config.before(:each, js: true) do
    DatabaseCleaner.strategy = :truncation, {except: config.seed_tables}
  end

  config.before(:each) do
    DatabaseCleaner.start
  end

  config.after(:each) do
    DatabaseCleaner.clean
  end

end

如您所知 background是 before 的别名用于功能测试(请参阅 this )。因此，您可以使用:

background(:all) do
  # set up some records that don't change between scenarios
end

background(:each) do # or background
  # set up some records that do change between scenarios
end
