Support caching for unit tests in Jest/Vitest (similar to Pytest implementation) #2043
Description
Feature request
We would like to request caching support for unit tests when using LangSmith with Jest/Vitest.
- Currently, caching appears to be implemented only for Pytest.
- No PRs or issues seem to exist for extending this to Jest/Vitest.
- Adding this would help reduce cost and improve efficiency when repeatedly running tests for AI agents.
Motivation
Running AI agent tests can be expensive and time-consuming. In Pytest, caching alleviates this by reusing previous results. Extending similar functionality to Jest/Vitest would:
- Make testing workflows more efficient.
- Reduce repeated costs during CI/CD pipelines.
Questions
- Is there any ongoing work to support this in Jest/Vitest?
- If not, would the maintainers be open to community contributions?
