assert/check/test/Empty

Validation checks to test if a given object is empty.

testEmpty(object, errormsg = "This is not an empty set")

checkEmpty(object, errormsg = "This is not an empty set")

assertEmpty(object, errormsg = "This is not an empty set")

Arguments

object	object to test
errormsg	error message to overwrite default if check fails

Value

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.

Examples

testEmpty(Set$new())
#> [1] TRUE
testEmpty(Set$new(1))
#> [1] FALSE
