Description

Expectation: is the object equivalent to a value? This expectation tests for equivalency: are two objects equal once their attributes have been removed.

is_equivalent_to(expected, label = NULL)
expect_equivalent(object, expected, info = NULL, label = NULL,
  expected.label = NULL)

Arguments

expected
