@MichaelChirico I am not sure which test this is referring to:

lintr/tests/testthat/test-with.R

Lines 17 to 18 in efacfea

	# TODO(michaelchirico): use plain expect_equal after waldo#133 makes it into a CRAN release
	# Here, the environment()s are different because factories use them.

That's the only TODO that remains related to the {waldo} update.

IINM that TODO's referring to this:

lintr/tests/testthat/test-with.R

Lines 26 to 27 in 5276c37

	expect_silent(result <- all.equal(linters_with_tags("default"), linters_with_defaults()))
	expect_true(result)

@MichaelChirico This should be ready for approval now.
