### test the sanity checks
### pretty obsessional doing this but I like it!

  ### sanity check 7
  ### if (length(fixYlim) != 1 | !is.logical(fixYlim)) {
  testthat::expect_error(plotBinconf(fixYlim = 1:3))
  testthat::expect_error(plotBinconf(fixYlim = "A"))
})

### there are no warnings to test
### I have not (as yet, perhaps never) created any test of the ggplot output
### feels too likely that it will change with tweaks of gpplot

### test comment:
### nothing to say!
