You can add your own support for the absent not_change
matcher.
by John Norris
You can test that mutliple attributes of an object have changed like this:
expect do
req
sku.reload
end.to change(sku, :code)
.and change(sku, :price)
But you can’t do the opposite:
expect do
req
sku.reload
end.to not_change(sku, :code)
.and not_change(sku, :price)
What you can do is define not_change
to support this:
RSpec::Matchers.define_negated_matcher :not_change, :change
