tox for piperider

Utilize tox to test the integration of dbt with various Python versions.

tox aims to automate and standardize testing in Python.

Usage

After installing tox, we can find the environment list by -l

$ tox -l
py38-dbt13
py39-dbt14
py39-dbt15
py39-dbt16
py310-dbt14
py310-dbt15
py310-dbt16
py311-dbt14
py311-dbt15
py311-dbt16

It will run tests in all environments if you are not pick up a specific environment

tox

You can run tests in a specific environment by -e

tox -e py38-dbt13

Run a chosen test case

We need to execute a selected test case for a deeper analysis. See this example:

========================================================================= short test summary info ==========================================================================
FAILED tests/test_dbt_util.py::TestRunner::test_load_dbt_resources - assert 1 == 2
========================================================== 1 failed, 91 passed, 12 skipped, 76 warnings in 5.39s ===========================================================
py38-dbt13: exit 1 (5.71 seconds) /Users/qrtt1/temp/piperider> pytest --color=yes pid=15609
.pkg: _exit> python /Users/qrtt1/temp/piperider/venv/lib/python3.10/site-packages/pyproject_api/_backend.py True setuptools.build_meta __legacy__
  py38-dbt13: FAIL code 1 (9.16=setup[3.44]+cmd[5.71] seconds)
  evaluation failed :( (9.32 seconds)

To execute, you can select:

  • A test file
  • A test suite
  • A specific test case

run a test file

tox -e py38-dbt13 -- tests/test_dbt_util.py

run a test suite

tox -e py38-dbt13 -- tests/test_dbt_util.py::TestRunner

run a test case

tox -e py38-dbt13 -- tests/test_dbt_util.py::TestRunner::test_load_dbt_resources
