Hey @wyrdforge, thanks for bringing this up! I am in fact able to replicate the issue and it looks like the syntax for this particular test is wrong. The test block should read like this:
test "it filters by age group", %{conn: conn} do
{:ok, view, _html} = live(conn, "/admin-dashboard")
params = %{"age_group_filter" => "18 and under"}
assert view
|> element("#age-group-form")
|> render_change(params) =~ "<title>2.00</title>"
end
Where [assert/1](https://hexdocs.pm/ex_unit/ExUnit.Assertions.html#assert/1) is called with the argument of the logical evaluation of pipeline_results =~ some_outcome. That is because the assert/`` function takes in an argument of some assertion, and our assertion should be “the resulting html from calling our pipeline does contain the given title element”.
The fix will be included in the next Beta release
