Using fixtures with association

Question

I have been following along on the Ruby track and I'm trying to write a test where the status should be no more than 150 characters. The status table contain user_id that is linked to the user in user table. Is this the right way to do it?
The test past but is it passing for the right reasons?
in users.yml
cassandra:
  firstname: "Cassandra"
  lastname: "Contiago"
 email: "cassandra@yahoo.com"
  profile_name: "Cassie"
in statuses.yml
one:
  user: cassandra
  content: A super long status that is over 150 characters and should not be saved. I am learning how to code at the moment and it's incredibly hot to stay in front of the laptop but I will persevere.
in status.rb
...
validates :content, length: {maximum: 150}, allow_blank: true
...
in statustest.rb
require 'testhelper'
class StatusTest < ActiveSupport::TestCase
  test "a status should be no more than 150 characters" do 
    status = Status.new
    status.content = statuses(:one).content
assert !status.save
assert !status.errors[:content].empty?
  end
end

You should always check in the browser to make sure that the test actually achieved what you wanted it to. Also instead of typing out a random message like you did you could multiply a short string to achieve the length you want and could go into test/unit/status_test.rb and forget about fixtures for that one since it is a model test. Add the following:
```rb
   test "that a status's content is no more than 150 characters long" do 
        status = Status.new
        status.content = "H" * 151
    assert !status.save
    assert !status.errors[:content].empty?
end
```
Here when you multiply the string it repeats and joins the string by the amount of times it has been multiplied.
