assert/check/test/ClosedBelow
Validation checks to test if a given object is closedbelow.
testClosedBelow(object, errormsg = "This is not a set closed below") checkClosedBelow(object, errormsg = "This is not a set closed below") assertClosedBelow(object, errormsg = "This is not a set closed below")
object |
object to test |
errormsg |
error message to overwrite default if check fails |
If check passes then assert returns object invisibly and test/check
return TRUE. If check fails, assert stops code with error, check returns
an error message as string, and test returns FALSE.
testClosedBelow(Interval$new(1, 10, type = "[]")) testClosedBelow(Interval$new(1, 10, type = "(]"))
