Require usage of expect_false(.) over expect_true(!.)
Source:R/expect_not_linter.R
expect_not_linter.Rd
testthat::expect_false()
exists specifically for testing that an output is
FALSE
. testthat::expect_true()
can also be used for such tests by
negating the output, but it is better to use the tailored function instead.
The reverse is also true -- use expect_false(A)
instead of
expect_true(!A)
.
