Description

iOS simulator app doesn't launch when 'detox test' command executed

Detox --loglevel verbose output shows [DetoxServer.js/CANNOT_FORWARD]

[x] I have tested this issue on the latest Detox release and it still reproduces

Reproduction

Detox tests were last running in April with the following setup

{
  "main": "node_modules/expo/AppEntry.js",
  "scripts": {
    "start": "expo start",
    "android": "expo start --android",
    "ios": "expo start --ios",
    "eject": "expo eject",
    "test": "jest"
  },
  "dependencies": {
    "expo": "^37.0.0",
    "react-native": "https://github.com/expo/react-native/archive/sdk-37.0.0.tar.gz",
  },
  "devDependencies": {
    "detox": "^15.3.0",
    "detox-expo-helpers": "^0.6.0",
    "expo-detox-hook": "^1.0.10",
    "jest-expo": "^37.0.0",
    "metro-react-native-babel-preset": "^0.53.1",
    "react-native-testing-library": "^1.12.0",
    "react-test-renderer": "^16.12.0",
  },
  "jest": {
    "preset": "jest-expo",
    "transformIgnorePatterns": [
      "node_modules/(?!(jest-)?react-native|react-clone-referenced-element|@react-native-community|expo(nent)?|@expo(nent)?/.*|react-navigation|@react-navigation/.*|@unimodules/.*|unimodules|@sentry/.*|sentry-expo|native-base|react-native-multi-slider|@ptomasroos/.*)"
    ],
    "setupFilesAfterEnv": [
      "<rootDir>/unit_tests/setupTests.js"
    ],
    "testMatch": [
      "<rootDir>/unit_tests/**/*.test.js?(x)"
    ]
  },
  "detox": {
    "test-runner": "jest",
    "configurations": {
      "ios.sim": {
        "binaryPath": "<app_name>.app",
        "type": "ios.simulator",
        "name": "iPhone 11 Pro Max"
      }
    }
  }
}

They are now failing as described above with the following package.json

{
  "main": "node_modules/expo/AppEntry.js",
  "scripts": {
    "start": "expo start",
    "android": "expo start --android",
    "ios": "expo start --ios",
    "eject": "expo eject",
    "test": "jest"
  },
  "dependencies": {
    "expo": "^37.0.0",
    "react-native": "https://github.com/expo/react-native/archive/sdk-37.0.0.tar.gz",
  },
  "devDependencies": {
    "detox": "^17.4.5",
    "detox-expo-helpers": "^0.6.0",

    ],
    "setupFilesAfterEnv": [
      "<rootDir>/unit_tests/setupTests.js"
    ],
    "testMatch": [
      "<rootDir>/unit_tests/**/*.test.js?(x)"
    ]
  },
  "detox": {
    "test-runner": "jest",
    "configurations": {
      "ios.sim": {
        "binaryPath": "<app_name>.app",
        "type": "ios.simulator",
        "name": "iPhone 11 Pro Max"
      }
    }
  }
}

Expected behavior

Running detox test should open the app in the simulator and execute tests.

Environment (please complete the following information):

Detox: 17.4.5
React Native: 0.61
Node: v14.5.0
Device: iOS simulator iPhone 11 pro max
Xcode: 11.3.1 (Using expo for development)
iOS: 13.3
macOS: 10.14.4

Try adding ‘disableSynchroniztion’.

After running detox test, the test code seems to stall at ‘await device.disableSynchronization’ (a console log is never called on the next line of code)

Manually launch the Simulator app from Xcode and see what happens on screen.

LeoNatan on 5 Sep 2020

We're using expo, so our app isn't launched from XCode. We get a .app and then install on a sim from command line. Like so:

xcrun simctl install booted <APP_NAME>
xcrun simctl launch booted <BUNDLE_ID>

Running xcrun simctl launch booted <BUNDLE_ID> from terminal launches the app on the simulator as expected

bryanboyko on 5 Sep 2020

I didn't say "launch your app from Xcode", I said launch the Simulator app from Xcode. Your first line of the issue says "iOS simulator app doesn't launch when 'detox test' command executed". When Detox boots a simulator runtime without the Simulator app running, you won't see what's going on. So launch the Simulator app, then start your test from Detox and see what happens.

Expo has had many issues with Detox in the past. I fear we can't assist if this is an Expo issue.

LeoNatan on 5 Sep 2020

Sorry my mistake. I meant that when the simulator app is open, running detox test installs our app successfully onto the simulator, but then doesn't launch our app in the simulator.

Starting a simulator from XCode and then running detox test has the same result. Our app installs on the simulator app but fails to launch.

In this case it may not be an expo issue because we create a complete build of our app for the simulator, .app, as opposed to using the Exponent.app machanism, and then manually install it on a simulator.

This method for getting a .app and then running detox tests with it was working a number of months ago.

bryanboyko on 6 Sep 2020

So, just to make sure, the doesn’t launch at all? Or does it launch and then closes right away? After the app installs and tests fail, does the app launch correctly when you tap the icon in the simulator?

LeoNatan on 6 Sep 2020

The app doesn't launch at all.

If I run detox test with the simulator open and our app not open, wait 10-20 while the test is hanging, and then click to open our app, our app opens normally.

If I run `detox test with the simulator open and our app not open, and wait 6 minutes (not sure if this consistently takes so long, but I waited it out a couple times), the app launches and then the tests timeout after another few minutes.

If I open our app on the sim and then run detox rest, a black screen shows up.

Is there any way you can obtain an Xcode project? We have a guide you can then follow to try to debug.

LeoNatan on 7 Sep 2020

It may be possible if we eject, but we are trying to avoid that in order to keep the advantages Expo offers in streamlining the development process.

Is there any documentation for debugging detox tests when run directly on a .app?

bryanboyko on 7 Sep 2020

Can you just temporarily eject so you can debug?
If something is crashing very early on, it won't be possible to debug with a precompiled product.

LeoNatan on 7 Sep 2020

I have the same problem with a Debug configuration on iOS. I'm not using Expo and a test release build works.

detox[38024] ERROR: [cli.js] Error: Command failed: jest --config e2e/config.json --testNamePattern '^((?!:android:).)*$' --maxWorkers 2 e2e

App has not responded to the network requests below: (id = -1000) isReady: {}

jarnove on 23 Sep 2020

Same issue also here, release builds work fine but make it very tedious to write tests.

debug builds seem to get stuck synchronising

17.5.3 seems to have broken debug-synchronization, prior to that I got this log:

detox[30240] INFO:  [actions.js] Sync App State: Waiting for network requests to finish: (
    "http://localhost:8081/index.bundle?platform=ios&dev=true&minify=false"
)

but I can see from my js server that the request has completed

as a work around I've tried to blacklist localhost but that also doesnt seem to work

  async initDetox() {
    const getDetoxURLBlacklistRegexFromDomains = domains =>
      `(${domains.map(domain => `\\".*${domain}.*\\"`).join(',')})`;

    const detoxURLBlacklistRegex = getDetoxURLBlacklistRegexFromDomains(['localhost']);
    const instance = await this.detox.init(null, { launchApp: false, detoxURLBlacklistRegex });

    await instance.device.launchApp({ detoxEnableSynchronization: 0, detoxURLBlacklistRegex });

    return instance;
  }

launchApp just hangs.

If I then kill the test and launch the app manually it launches fine

+1. I am experiencing the same issue and have tried similar workarounds.

treymcmeans on 28 Sep 2020

Guys, please follow the “debugging in Xcode” guide to see what’s going on. If you are using Expo and are willing to do this step, we will close the issue. We explicitly do not support Expo because of issues like these.

LeoNatan on 28 Sep 2020

I will go over the guide now and report back. I'm not using Expo

treymcmeans on 28 Sep 2020

Thanks

LeoNatan on 28 Sep 2020

Thanks for pointing me to the Debugging in Xcode article @LeoNatan. After setting a few breakpoints, I was able to find the function that was hanging up the startup process.

Appears that the EarlGrey functions and that one would not cooperate, creating the hang. Ended up creating a new target with a preprocessor macro to skip that part of the startup code. All working now

treymcmeans on 28 Sep 2020

Can you go into more details please? Was it Earl Grey swizzling? We intend to remove EG completely soon, want to make sure what we use instead has as little swizzling conflicts as possible.

LeoNatan on 28 Sep 2020

@treymcmeans Your issue is probably not the same issue @bryanboyko has.

"Stuck on launch" is a generic symptom of all issues that cause a start up crash and hang. So anyone having "this" issue, please follow the guide and provide the information.

LeoNatan on 28 Sep 2020

@LeoNatan
I ran into the issue "Stuck on launch" after upgrade from v16 to v17.

I followed the “debugging in Xcode” guide. With Detox.framework linked. I can reproduce the issue with a Xcode run.

Here's the log from Xcode console after func webSocket(_ webSocket: WebSocket, didReceiveAction type: String, params: [String : Any], messageId: NSNumber) received "loginSuccess".
