is_informative_error()
is a generic predicate that indicates
whether testthat users should explicitly test for an error
class. Since we no longer recommend you do that, this generic
has been deprecated.
is_informative_error(x, ...)
An error object.
These dots are for future extensions and must be empty.
A few classes are hard-coded as uninformative:
simpleError
rlang_error
unless a subclass is detected
Rcpp::eval_error
Rcpp::exception
