iOS UI testing - picker wheel adjusting only swipes by one item

Question

I am trying to write a test for UIPickerView to pick certain values. I use picker.adjust(toPickerWheelValue: pickValue) to do so. But the problem is that for some reason this only swipes picker by one value.

For example on the gif you can see that initial value was 52, then I called picker.adjust(toPickerWheelValue: "15") and it became 51 instead of 15, then I called it again and it became 50:

So the pattern is that it only changes it by one value up or down closer to the desired value.

What is the problem here?

Answer 1

Referencing with initial value works for me. So my code looks like this:

app.pickerWheels["52"].adjust(toPickerWheelValue: "15")
