Use this method to assert expected values of `stdout` and `stderr` after
running tabnanny.check() on given `dir` or `file` path. Because
tabnanny.check() captures exceptions and writes to `stdout` and
`stderr`, asserting standard outputs is the only way.

Because order of files returned by `os.lsdir()` is not fixed, verify the
existence of each output lines at `stdout` using `in` operator.
`verbose` mode of `tabnanny.verbose` asserts `stdout`.
