Question

在遵循the basic instructions for setting up Detox作为我的简单示例项目并运行成功的detox build之后，detox test会产生以下输出，即使我的{{1 }}适用于iOS：

package.json

错误中提到的文件由安装过程提供，没有更改，并且具有以下内容：

{
  "name": "Learn",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "start": "node node_modules/react-native/local-cli/cli.js start",
    "test": "jest"
  },
  "dependencies": {
    "react": "16.4.1",
    "react-native": "0.56.0"
  },
  "devDependencies": {
    "babel-jest": "23.4.0",
    "babel-preset-react-native": "5.0.2",
    "detox": "^8.0.0",
    "jest": "^23.4.1",
    "react-test-renderer": "16.4.1"
  },
  "jest": {
    "preset": "react-native"
  },
  "detox": {
    "configurations": {
      "ios.sim.debug": {
        "binaryPath": "ios/build/Build/Products/Debug-iphonesimulator/Learn.app",
        "build": "xcodebuild -project ios/Learn.xcodeproj -scheme Learn -configuration Debug -sdk iphonesimulator -derivedDataPath ios/build",
        "type": "ios.simulator",
        "name": "iPhone 6"
      }
    },
    "test-runner": "jest"
  }
}

为什么排毒无法测试我的应用程序？

更新：当我遵循instructions below时，我得到：

首先，Detox没有运行android测试。只是因为正则表达式中的negative lookahead而已。

--testNamePattern='^((?!:android:).)*$'

这是我刚刚运行的一次成功的iOS测试的输出。

detox test
node_modules/.bin/jest e2e --config=e2e/config.json --maxWorkers=1 --testNamePattern='^((?!:android:).)*$'

关于您的测试未运行，当我将React-Native版本从0.55升级到0.56时，我遇到了这个问题。

我相信Babel会导致此问题，因为RN 0.56现在需要Babel 7。

在查看package.json时，您似乎应该添加到devDependencies

"@babel/core": "^7.0.0-beta.47", "babel-core": "^7.0.0-beta.47",

已在React-Native github页面上讨论了此问题。

对于运行Jest测试，我发现我还必须添加 "@babel/generator": "^7.0.0-beta.47"到我的devDependencies。

Answer 2

还要检查这个是否正确

您的测试模拟器设备的名称与您在 detox.config.js 中提到的 avdName 完全相同

未指定排毒时尝试运行Android测试
