Laravel testing Failed asserting that two strings are equal

I am very new to testing, but have now found it essential to automate my testing.

I have a test that is working fine up until it gets to the link '/cart' it gets to the link '/cart' no problem, but any other link I try to click afterwards always ends up back at the cart.

here is my error after trying to navigate away from the cart.
