Update the Dockerfile to use the `$POETRY_HOME` argument to set the
Poetry home directory instead of adding Poetry to the PATH environment
variable.
Add instructions to the `CONTRIBUTING.md` file on how to run tests with
Docker.
Closes https://github.com/hwchase17/langchain/issues/2324
This makes it easy to run the tests locally. Some tests may not be able
to run in `Windows` environments, hence the need for a `Dockerfile`.
The new `Dockerfile` sets up a multi-stage build to install Poetry and
dependencies, and then copies the project code to a final image for
tests.
The `Makefile` has been updated to include a new 'docker_tests' target
that builds the Docker image and runs the `unit tests` inside a
container.
It would be beneficial to offer a local testing environment for
developers by enabling them to run a Docker image on their local
machines with the required dependencies, particularly for integration
tests. While this is not included in the current PR, it would be
straightforward to add in the future.
This pull request lacks documentation of the changes made at this
moment.
