Extend the test helper to treat types.untyped.DataPipe like DataStub by calling load() on actualValue before comparing.

Replace the old SKIP_PYNWB_COMPATIBILITY_TEST_FOR_TUTORIALS env var with SKIP_PYNWB_TESTS across tests and nwbtest.m, and update +tests/nwbtest.default.env.
Update CI workflow matrix keys and usage in prepare_release.yml, run_tests.yml, and configurations/matlab_release_matrix_strategy.yml to use the new key (matrix.skip-pynwb-tests) and wire the MATLAB setenv accordingly.
Move conditional installation of pynwb into the workflows (install pynwb only when skip-pynwb-tests == '0') and remove the direct git+ dependency from +tests/requirements.txt (update comment to reflect conditional installs).
Also add TestTags = {'UsesPython'} to PyNWBIOTest.
These changes centralize the CI control of pynwb installation and standardize the skip variable name.

checking if this class attribute trips up docs build
Move TestTags to methods blocks. Check if that fixes issue with sphinx build of docs
…nore-nwbinspector-subject-checks-in-tutorialtests
Install pynwb and nwbinspector from PyPI stable releases in the main test workflow so CI only fails due to matnwb regressions. Add a separate weekly workflow that tests against the dev branches to catch upstream incompatibilities early without blocking PRs. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Added more details in comments Removed unused vars NWB_TEST_DEBUG, GITHUB_TOKEN Added PYNWB_REPO_DIR
Replace custom venv/download/GitHub API infrastructure with a simple
approach: read tutorial files from PYNWB_REPO_DIR env var pointing to
a pre-cloned pynwb repo, and run them against the system Python. The
CI workflows are now responsible for cloning the repo and setting the
env var. TestTags = {'UsesPython'} added so the tag selector in the
dev workflow picks up these tests, and SKIP_PYNWB_TESTS correctly
excludes them on older MATLAB releases.

Covers prerequisites, running tests via nwbtest() and the MATLAB unit testing framework, Python dependency setup, environment variable configuration, and test authoring conventions. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
actions/checkout requires path to be within the workspace directory. Use path: pynwb-repo (inside workspace) instead of ../pynwb-repo. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Suppress output
Suppress warning that happens due to wrong values in the file's version attribute in the source schemas for v 2.2.0 and 2.6.0
Added section about setting up dynamically loaded filters
Move test tags to methods block, as testtags in classdef breaks the sphinx/docs build

Have you thought about the dimension ordering issue? I think Zarr will be in C order, not F order |
