Detox: Launch on Android fails - DEBUG: [DetoxServer.js/CANNOT_FORWARD] role=testee not connected, cannot fw action

[leugimmai]

Description

Currently as it stands my app builds fine and launches like normal when running react-native run-android. It is when I try to run the detox test is that things fail. The app will launch on my device shortly there after it just hangs and eventually crashes. I did the initial set up with android, and ran the detox-cli to add the e2e folder with tests as well.

Steps to Reproduce

Running: detox test -c debug

[lvmtam]

the same @leugimmai :(

[ZSeba]

same problem here 😢 .
Detox: 9.0.1
React Native: 0.56
Node: 10.9.0
Device: iPhone 7 Plus (ios simulator)
Xcode: 9.4.1
macOS: High Sierra

[noomorph]

I'll take a look in the next few days, so basically you are telling that the combination of Windows 10 + hardware device + debug mode does not work on detox. I'll check that too and get back to you.

Also, could you bump your detox version to 9? Anyway AFAIR the 8th version does not support RN 0.55 on Android.

[noomorph]

@leugimmai, could you submit crash details from adb logcat? @lvmtam, if you claim to have the same issue, you might send your crash log too.

[AntoineGrandchamp]

@noomorph I have the same problem.

[AntoineGrandchamp]

@noomorph Do you have any update on this ?

[noomorph]

@AntoineGrandchamp, thanks for submitting crash details. I believe that currently, the right person to contact will be @rotemmiz. He's most familiar with this part, though even now I can say that he will ask for more details. E.g. what kind of app do you have? Is it a greenfield or brownfield app? When do you load React Native?

Maybe you should get into Java debugger and see why it does not get a new reactContext... since anyway we don't have a public repository that reproduces your problem.

[noomorph]

Clarification. At the moment, the reason why this issue got a label accepted/bug is that detox does not print crash details and exit, though it should, in these situations. I firmly believe that the timeout mechanism of a test runner is the last resort, not the way to go. That's what is missing right now.

I got the same issue with API 18 on Android:

React Native: 0.56.1
Node: 8.12.0 (nvm)

It's working on API 19, not 18 !

I had the same problem with real devices, but I had no problem with emulators.

Hi, Just curious, is your packager server running in bg? When I run detox test, it does not launch the packager server and my app crashes, but when I launch the server, my tests execute properly.

It seems there is an issue with getting the current ReactContext

[mentormategeorgirusev]

@leugimmai @lvmtam @ZSeba @AntoineGrandchamp @selvakumardreams @rawqing
Has any one of you guys, found a solution/workaround?

[mentormategeorgirusev]

@rotemmiz - I've found the exact reason - react native navigation.
As a part of the set up of the navigation, the mainActivity extend is different.
See Android step 5
react-native-navigation guide

As for Detox we have
Not working
public class MainActivity extends NavigationActivity implements PermissionAwareActivity{
Working
public class MainActivity extends ReactActivity implements PermissionAwareActivity{

I'm playing with ReactNativeSupport.java, and trying to replace the interfaces, but to no avail.
Are you planing to make any changes in order to support apps with react-native-navigation?

[rotemmiz]

RNN uses Detox for its E2E suite, It is supported from the very beginning.
You need to further investigate

[mentormategeorgirusev]

@rotemmiz - that was helpful, I've played with RNN test app.
If I got it correctly, Detox will have no problems for android apps, using RectContext API
Unfortunately we are using redux, and we are not planing to migrate (we are close to release).

Is there a way to run Detox on app with redux?
If you have any test project, it will be very helpful.

[rotemmiz]

Detox does not understand JavaScript at all, it only monitors threads, native modules and native UI hierarchy. Redux has nothing to do with it.

[mentormategeorgirusev]

@rotemmiz you are absolutely right. I've managed to run the detox for android via fix in MainApplication.java

I know it is not relevant for detox, yet I'll share it here, so anyone with similar issue could save some time
MainApplication.java

Make sure you Override the getReactNativeHost() with the host you've created

public class MainApplication extends NavigationApplication implements ReactApplication {

    protected NavigationReactNativeHost mNavigationReactNativeHost = null;

//This is what Detox is shooting for
    @Override
    public ReactNativeHost getReactNativeHost() {
        return mNavigationReactNativeHost;
    }


//When creating ReactGateway, keep the host and reuse is in getReactNativeHost()
    @Override
    protected ReactGateway createReactGateway() {
      mNavigationReactNativeHost = new NavigationReactNativeHost(this, isDebug(), createAdditionalReactPackages()) {
          @Override
          protected String getJSMainModuleName() {
          return "index";
          }
      };
    return new ReactGateway(this, isDebug(), mNavigationReactNativeHost);
    }
}
