Compare Test Result Logs | Dataford Interview Questions

Implement a function to compare two versions of a test result log and identify added, removed, and changed entries.

Use compare_logs(old_log, new_log), where each log is a list of dictionaries with a unique id and a result value. Return a dictionary with added, removed, and changed lists. Preserve each log's input order. Added and removed lists contain complete entries. Each changed item contains id, before, and after entries. Treat an entry as changed when its result differs.

Constraints

0 <= len(old_log), len(new_log) <= 1000
Each entry is a dictionary containing a unique string id and a result value
An ID appears at most once in each log
Result values are strings
Output lists preserve the corresponding input log order

Function Signature

def compare_logs(old_log, new_log):
