Moved flask-talisman here from requires-testing because this is used in our tests themselves, not in dash.testing.

beautifulsoup4 has stated it's about to drop Py2 support, so I set a preemptive upper bound for Py2 at the current version.

These tests would fail previously if run in tandem with the integration tests, because they import and register various other component packages. After this change, I can simply call pytest locally to run all the Python-based tests in this repo.
There's still one that fails locally for me: The iframe sandbox test rdif001 fails on its last line - it can't see the log error it's supposed to have. I'm not sure what's going on here but it seems we've run afoul of some sort of security restriction: in the Chrome devtools I can't even see the DOM inside the iframe (though I can interact with this DOM via Selenium).
Anyway this test still runs fine on CI, but if what I'm seeing is new behavior in the latest Chrome (v87) we may need to sort this out soon.

Moving from warning to warning+error.
Changing the iframe sandbox options to

- fixes the problem on Chrome 87
- fixes the warning on Chrome 89 but the error remains

In both Chrome 87 and 89 localStorage is not accessible from data URL but in 89 it's shown from the start. In both 87/89 running window.localStorage from the console gives

To be clear, the test requires that a warning is logged so we're not trying to "fix" all the warnings. I'm not sure it's really important that we test for these logs, the main thing is that the app still works and doesn't error out trying to access cookies. So the easy answer here would be to simply remove the log check. But the "full" solution I guess would be to serve a real container page with an iframe in it, rather than a data: url, and keep the check as is.
For reference this feature was introduced in #1080

Could we sanity test these flake8/pylint changes against the other core repos?

They have an annoying habit of changing their rules..

Good call - they may well need their own updates to .pylintrc files, or syntax updates. PRs coming.

plotly/dash-core-components#907, plotly/dash-html-components#171, plotly/dash-table#857 - All three, I started with this branch, got tests passing, then reverted to the dev branch of dash and tests still pass - All that was required (other than prohibiting the latest xlrd) was a couple of linting exclusions.

Fixes#1466 - loosens all
dash[testing]requirements to>=for better compatibility with outside projects.In addition I made two other changes:
dash[dev]requirements. I had thought that this was only used by us internally, on CI, but in fact it's required for building components, and as such is referenced in the component boilerplate. So we may need to revisit this.dash.testingand getting rid of the lastunitteststyle tests.Contributor Checklist
