Then I should see 1 selected record

Assert the number of selected records, as the control panel reports it ("3 selected", .o_list_selection_box). With 0 the selection box must be gone.

Examples

Then I should see 1 selected record
And I should see 3 selected records
Then we should see 15 selected records
And I should see 0 selected records
Then we should see 2 selected records

Pattern

Then(/^(I |we )*should see (\d+) selected records?$/, …)
