Require usage of expect_type(x, type) over expect_equal(typeof(x), type)
Source:R/expect_type_linter.R
expect_type_linter.Rdtestthat::expect_type() exists specifically for testing the storage type
of objects. testthat::expect_equal(), testthat::expect_identical(), and
testthat::expect_true() can also be used for such tests,
but it is better to use the tailored function instead.
