I found that many of my tests were failing on iPads. I’m running several types of iPads. For tests that do complete, many of the tests come back null. Here’s the percentage of tests that completed for several types of iPads.

{
    "ipad-3-001": {
        "success": 518,
        "fail": 92,
        "total": 610,
        "percent": 0.8491803278688524
    },
    "ipad-air-001": {
        "success": 481,
        "fail": 119,
        "total": 600,
        "percent": 0.8016666666666666
    },
    "ipad-mini-001": {
        "success": 605,
        "fail": 15,
        "total": 620,
        "percent": 0.9758064516129032
    },
    "ipad-mini-retina-001": {
        "success": 475,
        "fail": 115,
        "total": 590,
        "percent": 0.8050847457627118
    },
    "ipad-mini-retina-002": {
        "success": 466,
        "fail": 134,
        "total": 600,
        "percent": 0.7766666666666666
    }
}

Are there plans to replace these native agents with the nodejs/selenium driver?
