Module: Test::Unit::Attribute::ClassMethods (Ruby 2.7.5)

attribute(name, value, options={}, *method_names) click to toggle source

Set an attribute to test methods.

@overload attribute(name, value)

@example
  attribute :speed, :slow
  def test_my_slow_method
    self[:speed] # => :slow
  end

@param [Object] name the attribute name
@param [Object] value the attribute value
@return [void]

@overload attribute(name, value, *method_names)

@example
  def test_my_slow_method1
    self[:speed] # => :slow
  end

  attribute :speed, :slow, :test_my_slow_method1, :test_my_slow_method2

  def test_my_slow_method2
    self[:speed] # => :slow
  end

@param [Object] name the attribute name
@param [Object] value the attribute value
@param [Array<Symbol, String>] method_names the test method names set the attribute
@return [void]

@overload attribute(name, value, options)

@example
  attribute :speed, :slow, keep: true
  def test_my_slow_method1
    self[:speed] # => :slow
  end

  def test_my_slow_method2
    self[:speed] # => :slow
  end

@param [Object] name the attribute name
@param [Object] value the attribute value
@option options [Boolean] :keep whether or not to set attribute to following test methods
@return [void]

@overload attribute(name, value, options, *method_names)

@example
  def test_my_slow_method1
    self[:speed] # => :slow
  end

  # There are no valid options for now.
  attribute :speed, :slow, {}, :test_my_slow_method1

  def test_my_slow_method2
    self[:speed] # => nil
  end

@param [Object] name the attribute name
@param [Object] value the attribute value
@param [Hash] options ignored
@param [Array<Symbol, String>] method_names the test method names set the attribute
@return [void]
