Upcoming test failure in R-devel #97
Description
R 4.6.0 will contain an enhanced summary.default() that produces a more useful summary for character vectors, see PR#16750. This change will soon be committed to R-devel, where 'network' will fail its checks from tests/testthat/test-i22-summary-character.R (added in #35), which essentially tests base R output (not actually any functionality of this package).
If you want to keep that test, it would probably be better to compare the output of calling the generic summary(x) for a character vector x before vs. after loading 'network' and test that they agree (so check that 'network' does not impose a different method). This is easier to test outside of 'testthat' (which already loads the package).
