无法使用detox运行测试用例

Question

​

​

在使用detox运行测试用例时，我遇到了下面的错误。我已经安装了所有依赖项作为其中的一部分。

Can't find a simulator to match with " iPhone 6 ", run 'xcrun simctl list' to list your supported devices.

configuration="ios.sim.debug" artifactsLocation="artifacts/ios.sim.debug.2019-01-31 12-14-41Z" node_modules/.bin/jest "e2e" --config=e2e/config.json --maxWorkers=1 '--testNamePattern=^((?!:android:).)*$'

      It is advised to only state a device type, and not to state iOS version, e.g. "iPhone 7"

Answer 1

这是因为将package.json中detox配置中的模拟器设置为系统上没有的模拟器

"detox": {
    "configurations": {
      "ios.sim.debug": {
        "binaryPath": "ios/build/Build/Products/Debug-iphonesimulator/myapp.app",
        "build": "RN_SRC_EXT=e2e.js xcodebuild -workspace ios/myapp.xcworkspace -scheme myapp -configuration Debug -sdk iphonesimulator -derivedDataPath ios/build",
        "type": "ios.simulator",
        "name": "iPhone 7" // <- this is where you define your simulator
      }
    },

您应该在终端中运行xcrun simctl list，以查看哪些模拟器可用。然后在您的detox配置中使用其中一个可用配置。您可以将其更改为"iPhone 7"或"iPhone 8"

我们需要升级AppleSimUtils.如果您在升级check out here时遇到问题
