Data import settings page's 3rd pane for Match Profiles: Header Caret Action

Purpose: To define the actions of the Header caret in the Data Import Settings Match Profiles header pane, except for the New action (UIDATIMP-138) and export action (UIDATIMP-174)

As a staff person
I want to be able to take actions on one or more Match Profile settings in my match profiles results list
So that I can easily work with these settings from the results list, rather than the individual match profile detail screen.

     • Header Actions
     • New match profile (preceded by the + icon) Note: see scenario 2 for the actions, same as UIDATIMP-138
     • Export selected (preceded by the down arrow icon, and followed by the number of match profiles) Note: no action for this button yet; see UIDATIMP-174
     • Select all (preceded by the select all icon)
     • Deselect all (preceded by the deselect all icon)
2. Scenario 2
   • Given the Header caret's New option
   • When a user clicks that
   • Open a create match profile screen and follow the same details as UIDATIMP-138
3. Scenario 3
   • Given the Header caret's Select all option
   • When a user clicks that
   • Then the checkboxes next to all match profiles should be checked
4. Scenario 4
   • Given the Header caret's Deselect all option
   • When a User clicks that

5. Scenario 5
   • Given the checkboxes next to each match profile in the 3rd pane
   • When a User checks or unchecks one or more of the individual rows' checkboxes
   • Then the checkbox at the top of the list should be unchecked (since not all of the rows are checked any more)
6. Scenario 6
   • Include standard automated testing coverage; add screenshot or other details to confirm test coverage is in place
