Here is my dashboard test:
/test/accessibility/apps/dashboard.ts
You can add it either to the same test file or as another test under

/kibana/test/accessibility/apps

The test can skip inspect mode as that is already been tested.

Dashboard Edit Mode :

• run a11y tests on Dashboard Edit mode in xpack
  Click on Edit pencil button on any sample data loaded, run a11y tests on edit mode main page -
  covering: a11y tests on edit visualization, clone panel, edit panel title, customize time range, inspect, create drilldown, full screen, replace panel, delete from dashboard.

Clicking on each of these options- will open other pops to make edits- will cover such test cases in other subsequent PRs.

I got two questions for you:

1. Can you please note down what are the differences between dashboard view mode and dashboard edit mode in the top menu. We will need tests for it.
2. "Clicking on each of these options- will open other pops to make edits- will cover such test cases in other subsequent PRs." - does this mean you won't be navigating back to dashboard app after going through these options or are you planning to cancel every edit action? Thanks!
