Instance Method Details

#devaluate(actual) ⇒ Array

Supports negative/converse assertion testing. This is also where magic happens.

Parameters:

• actual (Object) —

  the value returned from evaling the Assertion block

Returns:

• (Array) —

  response from either AssertionMacro#pass, AssertionMacro#fail or AssertionMacro#error

# File 'lib/riot/assertion_macros/empty.rb', line 22

def devaluate(actual)
  actual.empty? ? fail(expected_message(actual).to_not_be_empty) : pass(new_message.is_empty)
end

#evaluate(actual) ⇒ Array

Supports positive assertion testing. This is where magic happens.

Parameters:

• actual (Object) —

  the value returned from evaling the Assertion block

Returns:

• (Array) —

  response from either AssertionMacro#pass, AssertionMacro#fail or AssertionMacro#error

# File 'lib/riot/assertion_macros/empty.rb', line 17

def evaluate(actual)
  actual.empty? ? pass(new_message.is_empty) : fail(expected_message(actual).to_be_empty)
