def assert(arg = nil)
  arg = yield if block_given?
  assert_equal !!arg, true
end

#assert_equal(actual, expected) ⇒ Object

A basic assert helper that tests for Object equality. Tests for object equivalence rather than object identity since this is sufficient for most tests.

Parameters:

  • actual (Object) —

    The Object to compare.

  • expected (Object) —

    The expected value.
