assert_not_in_array

We have an assertion in rails tests assert_in_array that is used to check if an element exists in an ar开发者_JAVA技巧ray. Is there any reverse assertion for it like assert_not_in_array?

There is no such assertion, however you could do this:

assert (not array.include? element)

You might be looking for refute_includes

 refute_includes array_of_user_ids, user.id

another method is using assert_not_includes

so expanding on the answer from @drhenner, one could use:

assert_not_includes array_of_user_ids, user.id
