How do I figure the ID of an item in my fixtures file using minitest?

Question

I'm using Rails 5 with minitest. How do I know, in my test file, what the ID of one of my the items in my fixtures file is? I have the following schema

  create_table "lines", force: :cascade do |t|
    t.string  "route_long_name"
    t.string  "name"
    t.integer "system_type"
    t.string  "color"
    t.string  "onestop_id"
    t.string  "vehicle_type"
    t.string  "wheelchair_accessible"
    t.string  "bikes_allowed"
    t.index ["onestop_id"], name: "index_lines_on_onestop_id"
    t.index ["route_long_name"], name: "index_lines_on_route_long_name"
  end

Then in my test/fixtures/lines.yml, I create this fixture

one:
  id: "1"
  name: "line1"
  color: "green"

So in my minitest test, I try this

  test "get show page with valid line id" do
    test_line_id = "1"
    line = Line.find_by_id(test_line_id)
    puts "inspect1: #{line.inspect}"
    assert_not_nil line

    get line_url(line)
    line = assigns(:line)
    puts "inspect2 #{line.inspect}"
    assert_equal test_line_id, line.id
    assert_response :success
  end

But the line

 assert_equal test_line_id, line.id

dies with teh error

Expected: "1"
  Actual: "980190962"

So how do I figure out the ID of teh item in my fixtures file?

You don't need to do it that way.

If all you want is to make sure you are getting the URL for a valid line... then you can just get any line at all. You don't need to get it by id eg:

 test "get show page with valid line id" do
    # Get any line - it doesn't matter which
    line = Line.first
    assert_not_nil line

    get line_url(line)
    line = assigns(:line)
    assert_equal test_line_id, line.id
    assert_response :success
  end
