Instance Method Details
#assert_deprecated(deprecator, &block)
#assert_deprecated(match, deprecator, &block)
Asserts that a matching deprecation warning was emitted by the given deprecator during the execution of the yielded block.
assert_deprecated(/foo/, CustomDeprecator) do
CustomDeprecator.warn "foo should no longer be used"
end
The match
object may be a ::Regexp
, or ::String
appearing in the message.
assert_deprecated('foo', CustomDeprecator) do
CustomDeprecator.warn "foo should no longer be used"
end
If the match
is omitted (or explicitly nil
), any deprecation warning will match.
assert_deprecated(CustomDeprecator) do
CustomDeprecator.warn "foo should no longer be used"
end
