I have an `ideas_test.rb` file with 2 tests

```
test "create new idea" do
end
test "that Ideas are loaded in the index" do
end

```

When I run `rails test test/system/ideas_test.rb`, the 2nd test is executed first. Why is that?
Is there a way to force the order of tests?
Is the DB cleared between each Test?

Thanks in advance.
