Retrieve the iOS Simulator UDID

[cosminstirbu]

Thanks for the help.

What I’ve ended up doing though is writing the following Java piece of code that clears the NSUserDefaults for all installed simulators (since I don’t run any tests in parallel on multiple simulators):

private void clearIosUserDefaults() {
    try {
        String user = System.getenv("USER");
        String removeUserDefaultsCommand = "find /Users/" + user + "/Library/Developer/CoreSimulator/Devices/ -path \"*/Preferences/com.mycompany.myapp.plist*\" -exec rm -rf {} \\;";
        String[] shellCommand = new String[] {"/bin/sh", "-c", removeUserDefaultsCommand };

        Runtime.getRuntime().exec(shellCommand);
    } catch (IOException e) {
        e.printStackTrace();
    }
}

So far locally everything works great, hopefully I won’t run into permissions issues when I run this on Jenkins.

I also have a method that launches the application with clear local data:

public void launchAppWithClearedData() {
    if (Platform.isOnIOS()) {
        clearIosUserDefaults();
    }

    getDriver().launchApp();
}

This is kind of related to a different question that I’ve asked last week:

Reset NSUserDefaults / SharedPreferences

Hello, Is there a way to clear NSUserDefaults / SharedPreferences? I know that you can call resetApp() but that restarts the simulator itself (at least on iOS) and that takes a long time. I am more interested in closing the application and clearing the NSUserDefaults / SharedPreferences before each test in order to make them run faster rather than calling resetApp() Thank you.

Now, using a @Before hook, all I do is call launchAppWithClearedData and my app always runs from a well know state for each test (scenario).
