Class Method Details

.expect(expected, file, line, &block) ⇒ Object

Wraps the creation of an Object or one of its sub-classes by dispatching #to_lookout_expected on the expected value and then calling

#expect on the result, passing the expanded path to the FILE

containing the expectation, the LINE in file on which the expectation is defined, and the BLOCK to evaluate for the actual result.

If #to_lookout_expected raises NoMethodError, the result will be an Object, so that at least something gets set up.

Parameters:

Returns:

  • (Object) —

    The result of calling expected#to_lookout_expected#expect(FILE, LINE, &BLOCK)
