 At this point, you should be able to test locally.
 
+### A walkthrough
+
+1. Fork a test repo under [cachito-testing][] which uses the package manager you
+   need to test, and/or is otherwise related
+1. Clone the new fork to your local machine
+1. Create a new branch in the repo, named to reflect the purpose of your test(s)
+1. The goal here is to create what looks like a real
+   Go/Javascript/Python/whichever project, but simplified enough to *only* include
+   the required files which cachi2 needs to find and resolve dependencies
+1. Commit the test code, and push it to your fork in GitHub. Take note of the
+   commit hash.
+
+#### Testing your tests
+
+1. Add your pytest scenarios to the appropriate integration test source file
+   under 'cachi2/tests/integration'. You'll need to put the following in
+   `utils.TestParameters` for your test case
+
+   - `repo="https://github.com/cachito-testing/cachito-pip-without-deps.git"`  # this will be the name of the test repo you forked
+   - `ref="3fe2fc3cb8ffa36317cacbd9d356e35e17af2824"`  # this will be the commit hash noted previously
+   - `packages=({"path": ".", "type": "pip"},)`  # for pip, for example
+   - `check_vendor_checksums=False`  # or `True`, depending on the scenario
+
+1. In your local **cachi2** repo, make sure you have 'pytest' and 'jsonschema'
+  pip-installed in the cachi2 venv, so that you can run pytest without tox. Without
+  `tox`, it's **much** easier to run pytest with *only* your selected test
+  scanarios, and get useful, accessible logs
+1. Bonus: pip-install 'pytest-html' in the venv, and add (e.g.)
+   `--html=path_to_reports/pytest-report.html` to your `pytest` command line
+   for a very nicely formatted HTML report
+1. To summarize
+
+   - You're in the cachi2 repo directory
+   - Your test scenario's source is in 'tests/integration/test_foo.py'
+   - Your test scenario is called `test_foo_package`, and its pytest 'id' is
+     `foo_incorrect_checksum`
+
+1. Now run
+
+   ```bash
+   CACHI2_IMAGE=localhost/cachi2:latest pytest -rA -vvvv --confcutdir=tests/integration --log-cli-level=DEBUG tests/integration/test_foo.py::test_foo_package[foo_incorrect_checksum]
+   ```
+
+   which will run *only* 'tests/integration/test_foo.py::test_foo_package' with
+   it's "foo_incorrect_checksum" ID'd parameter set with a pre-built cachi2 container
+
 ## Running the test suite
 
 It's a good idea to run the whole cachi2 integration test suite, just to make
