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.

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

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

Now you can test and orchestrate using Meltano:

# Test invocation:
meltano invoke tap-looker --version

# OR run a test ELT pipeline:
meltano run tap-looker target-jsonl
