Testing Fundamentals - Testing Types and Levels

Which of the following is the correct way to describe regression testing?

Regression testing:

def regression_test(old_output, new_output):
    return old_output == new_output

AIt compares old and new outputs to detect changes

BIt trains a new model using old and new data

CIt visualizes differences between datasets

DIt deletes old test results before running new tests

Step-by-Step Solution

Solution:

Step 1: Analyze the function code
The function returns True if old_output equals new_output, meaning it compares outputs.
Step 2: Match function behavior to options
It compares old and new outputs to detect changes correctly states it compares outputs to detect changes; others describe unrelated actions.
Final Answer:
It compares old and new outputs to detect changes -> Option A
Quick Check:
Function compares outputs = It compares old and new outputs to detect changes [OK]

Quick Trick: Regression test checks if old and new outputs match exactly [OK]
