如何使用模拟器在Mac上使Appium在移动网络自动化上工作

Question

I am a long time Windows user but have been tasked with figuring out mobile automation on MAC for my company.

I am using Windows with Visual Studio and C# to write my automation scripts. I am able to run locally against Chrome, Firefox, IE, & Android for web applications using selenium. I am attempting to run on a MacBook Pro I just received to run my selenium tests against Safari on the iOS simulators. This is my first time using a Mac so I'm not at all familiar with how things work on that platform. Once we get mobile web figured out I will need to be looking into native apps as well.

My setup on the Mac is:

• OS X El Capitan Version 10.11.3
• MacBook Pro (Retina, 15-inch)
• 2.5GHz Intel Core i7, 16GB DDR3
• AMD Radeon R9 M370X 2048MB
• Xcode 7.2.1 (7C1002) with Apple Developer License (with all available Simulators downloaded)
• Appium 1.4.13 (Draco) installed from dmg downloaded from Appium.io.

When I run Appium Doctor I get the following:

I am not too concerned that Android isn't working as I never plan to run android from this machine.

This is the output of my instruments which I understand is just a list of the simulators:

My test script uses the following:

public static DesiredCapabilities GetiOS() {
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.SetCapability("browserName", "Safari");
capabilities.SetCapability("deviceName", "iPhone 6s");
capabilities.SetCapability("platformVersion", "9.2");
capabilities.SetCapability("platformName", "iOS");
return capabilities;
}

public static class DriverManager {
private static IOSDriver driver;
public static IOSDriver CurrentDriver { get { return driver; } set { driver = value; } }

    public static void SetDriver(DesiredCapabilities capabilities) {
        Uri serverUri = new Uri("http://192.168.1.8:4723/wd/hub");   // 192.168.1.8 is address for MacBook
        driver = new IOSDriver<IWebElement>(serverUri, capabilities, TimeSpan.FromSeconds(180));
        driver.Manage().Timeouts().ImplicitlyWait(TimeSpan.FromSeconds(5));
    }
}

I get the following output in Appium:

I have no idea where to go from here. It seems like it is trying to open a simulator with UDID B49CF332-0190-4F07-9BD5-3BDE2D3D170C but I have no idea where it is getting that from since it doesn't show up in my instruments output. I am using the default settings in the Appium GUI.

I really don't know where to turn from here. Any guidance would be greatly appreciated!

Answer 1

The real issue is this line: info: [debug] [INST STDERR] dyld: could not load inserted library '/Applications/Appium.app/Contents/Resources/node_modules/appium/submodules/appium-instruments/thirdparty/iwd7/InstrumentsShim.dylib' because no suitable image found.

There is a known fix for this.

1. Click the Apple logo to bring up IOS Settings
2. Select Advanced
3. Check "Use Native Instruments Library".
