Test between describe '...' do ... end does not take into account the test

I have a test that looks like this:

class PageTest < ActiveSupport::TestCase

  describe "test" do
    test "should not save without attributes" do
      page = Page.new
      assert !page.save
    end
  end

end

When running the tests, I get 0 tests, 0 assertions. If I remove the describe "test" do, I get the 1 test, 1 assertions. So I have the feeling that the describe "..." do is actually making the test disappear.

What is going on here? What am I missing?

Looks like you're mixing up minitest specs and ActiveSupport::TestCase. If you check the rails guides on testing the test method is explained but it's not used with describe.

Rails adds a test method that takes a test name and a block. It generates a normal MiniTest::Unit test with method names prefixed with test_. So,

test "the truth" do
  assert true
end

acts as if you had written

def test_the_truth
  assert true
end

The describe syntax is explained in the minitest docs under the spec section and is used with it (and not test). Like so:

 describe "when asked about cheeseburgers" do
   it "must respond positively" do
     @meme.i_can_has_cheezburger?.must_equal "OHAI!"
   end
 end
