* Ensure `tm.network` is paired with `@pytest.mark.network`
* Refactored test (by downloading data directly) that is not testing networking specifically

hmm there is an included `teams.cvs` is that intentional? > hmm there is an included `teams.cvs` is that intentional?

Yes this is expected. It was the test I referenced as "Refactored test (by downloading data directly) that is not testing networking specifically" @meeseeksdev backport 1.4.x Owee, I'm MrMeeseeks, Look at me.

There seem to be a conflict, please backport manually. Here are approximate instructions:

1. Checkout backport branch and update it.

```
git checkout 1.4.x
git pull
```

2. Cherry pick the first parent branch of the this PR on top of the older branch:
```
git cherry-pick -m1 2dd75ca5e04a18db9d79d9bed01726b40b6268e9
```

3. You will likely have some merge/cherry-pick conflict here, fix them and commit:

```
git commit -am 'Backport PR #45732: TST: Ensure tm.network has pytest.mark.network'
```

4. Push to a named branch:

```
git push YOURFORK 1.4.x:auto-backport-of-pr-45732-on-1.4.x
```

5. Create a PR against branch 1.4.x, I would have named this PR:

> "Backport PR #45732 on branch 1.4.x (TST: Ensure tm.network has pytest.mark.network)"

And apply the correct labels and milestones.
