cannot invoke remote function Phoenix.ConnTest.redirected_to/1 inside match

[nelsonic]

trying to follow the code on p.140 of Programming Phoenix book
and there's a test that checks that the page has been redirected to a given url.
but when we attempt to run the tests we see:

Looks like a typo on that test:
assert redirected_to(conn) = video_path(conn, :index) should be:
assert redirected_to(conn) == video_path(conn, :index)

@Danwhy thanks for confirming. 👍
