實例公開方法

assert_class_method(method, content, &block)

宣告所提供的類別方法存在於所提供的內容中。此方法不會偵測 (class << self) 內的類別方法,只會偵測以「self.」開頭的類別方法。若提供區塊,則會產生方法的內容。

assert_migration "db/migrate/create_products.rb" do |migration|
  assert_class_method :up, migration do |up|
    assert_match(/create_table/, up)
  end
end
# File railties/lib/rails/generators/testing/assertions.rb, line 88
def assert_class_method(method, content, &block)
  assert_instance_method "self.#{method}", content, &block
end

assert_directory(relative, *contents)

別名為: assert_file

assert_field_default_value(attribute_type, value)

宣告所提供的屬性類型取得適當的預設值

assert_field_default_value :string, "MyString"
# File railties/lib/rails/generators/testing/assertions.rb, line 117
def assert_field_default_value(attribute_type, value)
  if value.nil?
    assert_nil(create_generated_attribute(attribute_type).default)
  else
    assert_equal(value, create_generated_attribute(attribute_type).default)
  end
end

assert_field_type(attribute_type, field_type)

宣告所提供的屬性類型正確定義到欄位類型

assert_field_type :date, :date_select
# File railties/lib/rails/generators/testing/assertions.rb, line 110
def assert_field_type(attribute_type, field_type)
  assert_equal(field_type, create_generated_attribute(attribute_type).field_type)
end

assert_file(relative, *contents)

宣告所提供的檔案存在。您需要提供絕對路徑或相對的路徑到組態好的目的地

assert_file "config/environment.rb"

您也可以提供額外的參數。如果參數是正規表示法,它會檢查正規表示法是否符合所提供的檔案內容。如果是字串,會將檔案與所提供的字串做比對。

assert_file "config/environment.rb", /initialize/

最後,若提供區塊,則會產生檔案內容

assert_file "app/controllers/products_controller.rb" do |controller|
  assert_instance_method :index, controller do |index|
    assert_match(/Product\.all/, index)
  end
end
也別名為: assert_directory
# File railties/lib/rails/generators/testing/assertions.rb, line 25
def assert_file(relative, *contents)
  absolute = File.expand_path(relative, destination_root)
  assert File.exist?(absolute), "Expected file #{relative.inspect} to exist, but does not"

  read = File.read(absolute) if block_given? || !contents.empty?
  assert_nothing_raised { yield read } if block_given?

  contents.each do |content|
    case content
    when String
      assert_equal content, read
    when Regexp
      assert_match content, read
    end
  end
end

assert_initializer(name, *contents, &block)

宣告所提供的初始值存在。您需要提供相對的路徑到「config/initializers/」目錄。

assert_initializer "mail_interceptors.rb"

您也可以提供額外的參數。如果參數是正規表示法,它會檢查正規表示法是否符合所提供的檔案內容。如果是字串,會將檔案與所提供的字串做比對。

assert_initializer "mail_interceptors.rb", /SandboxEmailInterceptor/

最後,若提供區塊,則會產生檔案內容

assert_initializer "mail_interceptors.rb" do |initializer|
  assert_match(/SandboxEmailInterceptor/, initializer)
end
# File railties/lib/rails/generators/testing/assertions.rb, line 141
def assert_initializer(name, *contents, &block)
  assert_file("config/initializers/#{name}", *contents, &block)
end

assert_instance_method(method, content)

斷言在提供的內容中存在所給予的方法。若給予區塊,它將會產生方法的內容。

assert_file "app/controllers/products_controller.rb" do |controller|
  assert_instance_method :index, controller do |index|
    assert_match(/Product\.all/, index)
  end
end
別名為:assert_method
# File railties/lib/rails/generators/testing/assertions.rb, line 100
def assert_instance_method(method, content)
  assert content =~ /(\s+)def #{method}(\(.+\))?(.*?)\n\1end/m, "Expected to have method #{method}"
  assert_nothing_raised { yield $3.strip } if block_given?
end

assert_method(method, content)

assert_migration(relative, *contents, &block)

斷言指定的遷移存在。您需要提供一個絕對路徑或相對應的配置目標路徑

assert_migration "db/migrate/create_products.rb"

本方法將操作指定的路徑並試著尋找與遷移名稱相符的任何遷移。例如,上面的呼叫會轉換為

assert_file "db/migrate/003_create_products.rb"

因此,assert_migration 會沿用 assert_file 的參數。

# File railties/lib/rails/generators/testing/assertions.rb, line 64
def assert_migration(relative, *contents, &block)
  file_name = migration_file_name(relative)
  assert file_name, "Expected migration #{relative} to exist, but was not found"
  assert_file file_name, *contents, &block
end

assert_no_directory(relative)

assert_no_file(relative)

斷言指定的檔案不存在。您需要提供一個絕對路徑或相對應的配置目標路徑

assert_no_file "config/random.rb"
# File railties/lib/rails/generators/testing/assertions.rb, line 47
def assert_no_file(relative)
  absolute = File.expand_path(relative, destination_root)
  assert !File.exist?(absolute), "Expected file #{relative.inspect} to not exist, but does"
end

assert_no_migration(relative)

斷言指定的遷移不存在。您需要提供一個絕對路徑或相對應的配置目標路徑

assert_no_migration "db/migrate/create_products.rb"
# File railties/lib/rails/generators/testing/assertions.rb, line 74
def assert_no_migration(relative)
  file_name = migration_file_name(relative)
  assert_nil file_name, "Expected migration #{relative} to not exist, but found #{file_name}"
end
