"langgraph test" doesn't work with latest langgraph

[junan-trustarc]

Checked other resources

• I added a very descriptive title to this issue.
• I searched the LangGraph/LangChain documentation with the integrated search.
• I used the GitHub search to find a similar question and didn't find it.
• I am sure that this is a bug in LangGraph/LangChain rather than my code.
• I am sure this is better as an issue rather than a GitHub discussion, since this is a LangGraph bug and not a design question.

Description

"langgraph up" is working however "langgraph test" complains with dependencies, could you update constraints.txt to make it working? thanks.
