Trivia Bot Test Suite

Problem/Feature Description

Your team has built a context-aware trivia bot that adjusts its behavior based on the conversation history. The bot is smart enough to detect when a user has already asked about a particular category earlier in the session, and it tailors follow-up responses accordingly. It also enforces a rule: if a user asks a question about a banned topic, it raises a custom BannedTopicError exception rather than returning a reply.

A QA engineer needs a pytest test suite that covers the bot's history-aware behavior and its error handling. The engineer wants to verify: (a) that when conversation history is pre-loaded with some prior exchanges, the bot correctly reads that history and adjusts its next reply; (b) that when the bot raises BannedTopicError, the exception travels out of the turn-driving call unmodified so tests can catch it, and that the conversation remains inspectable afterwards — the failed turn should still be accessible; (c) that the full dialogue can be rendered as plain text for use in diagnostic output.

The bot adapter is a pure Python callable — no external services or API keys are needed.

Output Specification

Produce the following files in your working directory:

• trivia_bot.py — the bot adapter implementing the context-aware trivia logic and the BannedTopicError exception class
• test_trivia_bot.py — the pytest test suite covering the three scenarios described above
• results.txt — the output of running pytest -v test_trivia_bot.py, captured to this file

All tests should pass. The results.txt file should contain the full pytest output including individual test names and their pass/fail status.
