Example

check_that() takes an object you want to check, and a number of checks to run against the object. A check is usually a function that takes the object as the first argument and returns a boolean value of whether the check passed (TRUE) or failed (FALSE).

results <- mtcars %>%
  check_that(
    is.data.frame, # this should PASS
    is.character,  # this should FAIL
  )

print(results)
#> -- RESULTS ------------------------------------------------- [2] --
