The difference in his batting in Tests and LOIs clearly shows how LOI batting can be more challenging than Test batting in certain situations.
That is why the notion that Test cricket is harder than white ball cricket is false; it is actually different, and there several players who actually find batting in white ball cricket harder.
Faheem is one of those players. He melts like ice-cream when he has to cope with run rate pressure and field restrictions. In Test cricket, he has the luxury to bat at his own pace and does not have to worry about field restrictions.
Most important word in your post is 'in certain situations'
Not always. There are lot of other factors involved. We can never come to the conclusion whether test cricket is harder or ODis are.
