  We introduce the TimeGym Forecasting Debugging Toolkit, a Python library for
testing and debugging time series forecasting pipelines. TimeGym simplifies the
testing forecasting pipeline by providing generic tests for forecasting
pipelines fresh out of the box. These tests are based on common modeling
challenges of time series. Our library enables forecasters to apply a
Test-Driven Development approach to forecast modeling, using specified oracles
to generate artificial data with noise.
