#not_to_now(matcher) ⇒ Object Also known as: not_to, not_now_to, to_not, to_not_now

def not_to_now(matcher)
  RSpec::Matchers::BuiltIn::ChangeToValue.new(@change_details, negate(matcher)).from(matcher)
end

#to_now(matcher) ⇒ Object Also known as: now_to

Passes if matcher fails on the result of the change block before the expectation block and passes after.

In implementation, this is identical to

change {}.to eq { }`

is the same as

change {}.to_now eq(1)
change {}.from(negate(eq(1))).to(eq(1))

Examples:

expect({ @x = 1 }.to change { @x }.to_now eq 1
