I can test the content after a redirection like this
assert "/url" = redir_path = redirected_to(conn, 302)
conn = get(recycle(conn), redir_path)
assert html_response(conn, 200) == "Content after redirection"
But I cannot add a param variable to the assert url like this:
id = 10
assert "/url/#{id}" = redir_path = redirected_to(conn, 302)
It complains with:
cannot invoke remote function id/0 inside match
So if I just define the path like this before using it:
url_path = "/url/%{id}"
assert url_path = redir_path = redirected_to(conn, 302)
warning: variable "url_path" is unused
?? unusued? is it being used inside the assert...
Not sure how to silence that warning or how to approach this.
The code is similar to Chris's response here:

warning: variable "url_path" is unused

No, it's not. Your assert will match any value because if you have a variable name on the LHS of a match, it matches any value and that variable gets assigned the value of the RHS.
In:
foo = 10
assert foo = 20
IO.inspect foo
the assert passes and foo is printed as 20.
If you just want to assert that that string equals the value returned by redirected_to/2, you can use ==:
assert "/url/#{id}" == redirected_to(conn, 302)
