rails strange unit test fails

I try to run this simplest unit test:

   test "the truth" do
     assert true
   end

like this:

ruby -Itest test/unit/my_model_test.rb

(there is the only one test in the file, and actually in the whole site)

it fails with this message:

ActiveRecord::RecordNotUnique: SQLite3::ConstraintException: column email is not unique: INSERT INTO "users"... [some values to insert here]

now I do have a table named "users" but other than that I have never asked to do any tests on it nor do I even have such tests. Where does this error come from? How do I run just my test?

EDIT: the "users" table comes from the devise gem if that helps

Quote from http://guides.rubyonrails.org/testing.html

Rails by default automatically loads all fixtures from the test/fixtures folder for your unit and functional test. Loading involves three steps:

  • Remove any existing data from the table corresponding to the fixture
  • Load the fixture data into the table
  • Dump the fixture data into a variable in case you want to access it directly

So I think you need to check those fixtures. Also I suggest you to read that tutorial. It is very well written.
