poetry run pytest

You can also test the tap-openweathermap CLI interface directly using poetry run:

Testing with Meltano

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

Your project comes with a custom meltano.yml project file already created. Open the meltano.yml and follow any "TODO" items listed in the file.

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

# Install meltano
pipx install meltano
# Initialize meltano within this directory
cd tap-openweathermap
meltano install

Now you can test and orchestrate using Meltano:

# Test invocation:
meltano invoke tap-openweathermap --version
# OR run a test `elt` pipeline:
meltano elt tap-openweathermap target-jsonl
