使用NSPredicate在XCUITest中的单元格中搜索

Question

Ive been using XCUITest to perform some UI Automation. I have a collection of cells on a page, and want to return the ones that contain a label

Setting a breakpoint and typing in

po app.cells

returns

Output: {
      Cell 0x6080003603c0: traits: 8589934592, {{162.9, 184.6}, {916.5, 83.6}},  label: 'reminder same title, description, 4.38 pm'

I understand that an easier way would be to have accessibility identifiers associated with the Cells that have labels, but Im unsure of how to structure a NSPredicate query in order to probe the Cells collection and only return the Cells containing a label.

Answer 1

This should give you all the cells whose label is not nil

let predicate = NSPredicate(format: "label != nil")
let cells = XCUIApplication().cells.matching(predicate)
