# Which issue does this PR close?
Closes #696
# Rationale for this change
This PR sets up a work flow to generate TPH-C 1Gb data set in CI, runs the
22 examples, and compares their results to the
known answer file. By adding this PR we improve the robustness of our test
suite.
# What changes are included in this PR?
This PR adds the following changes:
- Adds CI workflow to generate TPH-C data set and answer file. The results
are cached from run to run.
- Adds pytest file to run all 22 examples and compare them to the answer file
- Exposes substring operation that was missing. Sometime between 36.0.0 and
38.0.0 substr was performing the operation instead.
# Are there any user-facing changes?
`substring` function exposed in python.
# Additional context
This PR replaces https://github.com/apache/datafusion-python/pull/710 which
contains a lot of intermediate testing steps. This MR should be cleaner to
review.
