Hi
I have a test that checks the length of a username
def test_name_length
users(:bob).name = "mo"
assert !users(:bob).save
assert_equal 1, users(:bob).errors.count
end
The format of the username is validated this way:
validates_format_of :name, :with => /^[[:alnum:]_-]{3,30}$/i
This test works… but when I use a name longer than 2 (the minimum
chars in the regex - 1) characters, a NoMethodError is raised:
- Error:
test_name_length(UserTest):
NoMethodError: You have a nil object when you didn’t expect it!
You might have expected an instance of Array.
The error occured while evaluating nil.+
