visual-studio-mac - Xamarin.UITest 2.2.4 启动会话在第一次测试中失败
问题描述
由于我的 macOS 让我更新到 XCode 9.3，我不得不将 Xamarin.UITest 从 2.2.2 升级到 2.2.4。
问题是，当我运行所有测试时，每次第一个测试都失败并附加错误。我认为这不是测试问题，因为所有测试都可以在带有 XCode 9.2 和 Xamarin.UITest 2.2.2 的 macOS 上正确运行。此外，如果我删除该测试，那么下一个将成为第一个测试的测试将失败并出现相同的错误。
任何人都可以帮助我吗？非常感谢您！

解决方案
我使用一个脚本来启动模拟器并在执行测试之前等待——这似乎有助于解决这些问题。
如果您想在执行测试之前安装 .app 文件，还有一个可选的 .app 文件路径：
#!/bin/sh -
# Boots the iOS simulator using specified OS and simulator name
set -e
SIMULATOR_VERSION="${1:?You must pass an iOS version as the first argument}"
SIMULATOR_NAME="${2:?You must pass a simulator name as the second argument}"
OPTIONAL_APP_PATH="$3"
SIMULATOR_GUID="$(xcrun simctl list | grep -vi unavailable | sed -e "1,/^-- iOS $SIMULATOR_VERSION --\$/d" -e '/^-- .* --$/,$ d' | grep -E "^\s+$SIMULATOR_NAME \(" | sed -e 's/^[^(]*(//g' -e 's/).*//g' | tail -1)"
if [ -z "$SIMULATOR_GUID" ]; then
echo "ERROR: Could not find simulator GUID for $SIMULATOR_NAME" >&2
exit 123
fi
shutDownSimulator()
{
GUID=$1
echo "==> Shutting down simulator with GUID $GUID..."
if xcrun simctl shutdown "$GUID" ; then
sleep 10s
echo "==> Successfully shutdown desired simulator."
else
echo "==> Desired simulator is already in shutdown state."
fi
}
eraseSimulator()
{
GUID=$1
echo "==> Erasing..."
xcrun simctl erase "$GUID"
echo "==> Waiting for 30 seconds..."
sleep 30s
}
bootSimulator()
{
GUID=$1
echo "==> Booting..."
xcrun simctl boot "$GUID"
echo "==> Waiting for 30 seconds..."
sleep 30s
}
installOptionalAppFile()
{
GUID=$1
if [ -z "$OPTIONAL_APP_PATH" ] ; then
echo "==> No app file to install specified, continuing..."
else
if [ -e "$OPTIONAL_APP_PATH" ]
then
echo "==> Installing app file at $OPTIONAL_APP_PATH"
xcrun simctl install "$GUID" "$OPTIONAL_APP_PATH"
else
echo "==> App file was not found at path: $OPTIONAL_APP_PATH"
fi
fi
}
echo "==> Erasing and launching simulator with name: $SIMULATOR_NAME / iOS version: $SIMULATOR_VERSION / GUID: $SIMULATOR_GUID..."
shutDownSimulator "$SIMULATOR_GUID"
eraseSimulator "$SIMULATOR_GUID"
bootSimulator "$SIMULATOR_GUID"
echo "==> Launching Simulator app..."
open `xcode-select -p`/Applications/Simulator.app
echo "Waiting for simulator to boot for 120 seconds..."
sleep 120s
installOptionalAppFile "$SIMULATOR_GUID"
exit 0
2 分钟的等待时间可能太长了，但我这样做是为了以防我的一些 Mac Mini 有点旧
