PyTest - Writing Assertions

Given this code, which assertion correctly verifies that obj is not the same object as None in pytest?

obj = []

Aassert obj == None

Bassert obj != None

Cassert obj is None

Dassert obj is not None

Step-by-Step Solution

Solution:

Step 1: Understand identity vs equality with None
To check if obj is not the None object, use is not None.
Step 2: Eliminate incorrect options
!= None and == None check value equality, which is less precise; is None checks identity but is opposite of what is needed.
Final Answer:
assert obj is not None -> Option D
Quick Check:
Use 'is not None' for identity checks [OK]

Quick Trick: Use 'is not None' to check object is not None [OK]
