Testing with Meltano

Note: This target will work in any Singer environment and does not require Meltano. Examples here are for convenience and to streamline end-to-end orchestration scenarios.

Next, install Meltano (if you haven't already) and any needed plugins:

# Install meltano
pipx install meltano
# Initialize meltano within this directory
cd target-s3-polars
meltano install

Now you can test and orchestrate using Meltano:

# Test invocation:
meltano invoke target-s3-polars --version

# OR run a test ELT pipeline with the Smoke Test sample tap:
meltano run tap-smoke-test target-s3-polars
