Which of the following is a valid assert statement in pytest?
Aassert x = 5
Bassert(x=5)
Cassert x equals 5
Dassert x == 5
Step-by-Step Solution
Solution:

  1. Step 1: Review correct assert syntax

    In pytest, assert is followed by a condition without parentheses or assignment.

  2. Step 2: Check each option

    assert x == 5 uses correct syntax. assert(x=5) uses assignment (=) inside parentheses, invalid. assert x = 5 uses assignment (=), invalid. assert x equals 5 uses invalid syntax.

  3. Final Answer:

    assert x == 5 -> Option D

  4. Quick Check:

    assert syntax = condition with == [OK]
Quick Trick: Use 'assert condition' with double equals for comparison [OK]
Common Mistakes:
MISTAKES
  • Using single equals instead of double
  • Adding unnecessary words
  • Using parentheses incorrectly
