📄 Description

Adds comprehensive unit tests for #597 and PR #612.

Summary

This PR adds unit tests for the SystemMessage type support in the system_prompt parameter of create_deep_agent(). These tests are designed to work with PR #612 which implements the feature to align with langchain.agents.create_agent.

Tests Added

  • String system_prompt (existing behavior)
  • SystemMessage system_prompt (new behavior from #597)
  • None and default system_prompt
  • Complex content in SystemMessage
  • Empty string and empty SystemMessage content

All 7 tests pass when run on top of PR #612.

Note

This PR is based on the improve-create-deep-agent branch from PR #612 and should be reviewed/merged alongside it.

Related: #597, #612
