How do i test for an entity relative to a player

Question

Im looking for a way to test if an entity is at a player's coordinates.
I've tried
/testfor @e[type=Shulker,name=Code] @a[r=1]

But it gives this
Data tag parsing failed: Invalid tag encountered, expected '{' as first char.

You should use /execute to have the command executed from the player rather than the command block:

/execute @a ~ ~ ~ /testfor @e[type=Shulker,name=Code,r=1]
