simctl + xcodebuild改变模拟器状态

Question

我正在尝试自动化我在项目中进行的功能测试。为此，我使用Jenkins并使用post-receive git hook运行测试任务。正确调用该作业，但在运行测试之前，我需要擦除模拟器以便测试应用程序的第一次启动。我做以下事情：

#!/bin/bash --login

# simulator we want
sim="iPhone 6"

# close the iOS simulator if open
echo "Trying to close iOS Simulator"
osascript -e 'tell app "iOS Simulator" to quit'

# find all booted devices
booted=( $(xcrun simctl list | sed -n 's/.*(\(.*\)) (Booted)/\1/p') )
if [ ${#booted[@]} != 0 ]; then
    echo 'Found the following booted devices:'
    for device in ${booted[@]}
    do
        echo $device
    done
else
    echo 'There are no booted devices, skipping'
fi

# shutdown all of them to be able to erase them
for device in ${booted[@]}
do
    echo "Trying to shutdown $device"
    xcrun simctl shutdown $device
    echo "Done"
done

# sanity check, all devices should be shutdown
booted=( $(xcrun simctl list | sed -n 's/.*(\(.*\)) (Booted)/\1/p') )
if [ ${#booted[@]} != 0 ]; then
    echo 'Even though we shut down all the devices, some devices are still booted:'
    for device in ${booted[@]}
    do
        echo $device
    done
    exit 1
fi  

# erase the device so we can test index page and tutorial
allDevices=( $(xcrun simctl list | sed -En 's/.* \((.*)\) \((Shutdown)\)/\1/p') )
for device in ${allDevices[@]}
do
    echo "Erasing device $device"
    xcrun simctl erase $device
    echo
done

# sanity check, all devices should be shutdown
booted=( $(xcrun simctl list | sed -n 's/.*(\(.*\)) (Booted)/\1/p') )
if [ ${#booted[@]} != 0 ]; then
    echo 'Even though we shut down all the devices, some devices are still booted:'
    for device in ${booted[@]}
    do
        echo $device
    done
    exit 1
fi

echo device list:
echo $(xcrun simctl list)

dev=( $(xcrun simctl list | sed -En 's/'"$sim"' \((.*)\) \((Shutdown)\)/\1/p') )
echo Booting the device $dev
xcrun simctl boot $dev

# clean is not good enough, need to remove DerivedData contents manually
rm -rf ~/Library/Developer/Xcode/DerivedData

/usr/local/bin/xctool -workspace MyApp.xcworkspace -scheme MyApp_QA2 clean

xcodebuild -workspace MyApp.xcworkspace -scheme MyApp_QA2 -destination 'platform=iOS Simulator,name=iPhone 6,OS=8.1' test | xcpretty -c -r html

当我运行这个时，我得到：

这些行负责启动：

dev=( $(xcrun simctl list | sed -En 's/'"$sim"' \((.*)\) \((Shutdown)\)/\1/p') )
echo Booting the device $dev
xcrun simctl boot $dev

所以，我评论他们，但随后构建失败了：

2015-03-10 09：56：13.036 xcodebuild [84840：4008451] [MT] iPhoneSimulator：无法连接到“com.apple.instruments.deviceservice.lockdown”（错误域= com.apple.CoreSimulator.SimError代码= 146 “无法在当前状态下查找：关闭”UserInfo = 0x7fbcb2f00af0 {NSLocalizedDescription =无法在当前状态下查找：关机}）

在我看来，像Xcode和simctl不能同意哪一个应该负责启动正确的SIM卡。有任何想法吗？

Answer 1

您可以使用xcrun instruments -w "iPhone 5 (8.4 Simulator)"启动模拟器并使用killall "iOS Simulator"关闭模拟器

Answer 2

在Xcode 6和Xcode 7中，Simulator.app负责引导它使用的设备。如果你使用simctl来启动设备，Simulator.app将无法在该状态下使用它，因为它将被启动到无头状态。
