Not enough info here, but try Emulator with API 27, does it work ?

After upgrading to Detox 8.0 I am also seeing my tests on Android timeout.

I don't have the best understanding of the entire Android connection process, but it looks like the first command is sent before the "isReady" command is received. Unfortunately I cannot provide a sample RN app since I am working with a client under NDA.

As you can see, the command that says look for element with text 'Log in' is executed after receiving the ready onMessage, but in 8.0.0 that command is executed before the ready onMessage.

Here are some sanitized sample logs:

Well, now that you can easily create logcat logs with artifacts manager, please provide them

[lalka-workco]

I cannot generate the new artifacts. When I try to use the --record-logs all flag I get the following error:

Since we are using Jest I used your example file from the Docs here

I'm not sure where the jasmine variable is coming from but I'm not sure we use that in our code, but removing that generates an error saying that line is required.

EDIT: My settings are a little different than @Papeone -- I am using RN 0.55.4, Node 9.2.0 and Nexus_5X_API_27 Emulator

[rotemmiz]

Does 0.55 works for you with Detox 7 ??
If these logs don't work, try using adb logcat and paste the log here.

Yes, I have Android running on 7.3.7 now on another branch. I attached one test run, let me know if this is helpful. The app builds and launches to the home screen, but the first action never takes place and it timeouts.

[ibaozi-cn]

I change detox version to 'v7.4.3'，It can run normally，Thanks @lalka-workco @rotemmiz

[noomorph]

@lalka-workco , @Papeone , I was thinking about it lately... Do you have launchApp: false somewhere in detox.init() method call?

[lalka-workco]

@noomorph Yes. It is in my init.js. I do not use the default because I need to set permissions for things like location and notifications.

// init.js

import detox from 'detox';

const config = require('../package.json').detox;

// Set the default test timeout of 120s
jest.setTimeout(120000);

beforeAll(async () => {
  await detox.init(config, { launchApp: false });
});

afterAll(async () => {
  await detox.cleanup();
});

[noomorph]

@lalka-workco , thanks much! I was fixing the other things around when a sudden realization struck me. It is indeed a bug in artifacts manager, and I already know where the problem is, and hopefully I'll get a fix for it released this week. Let's be in touch about this. Sorry for the inconveniences. 😊

UPD: created a dedicated issue to it: #856

[noomorph]

This issue thread is a duplicate of already existing issues, hereby I close it.

@Papeone had an issue described in: #831 (resolved in the unreleased yet ^8.0.1).
@lalka-workco had an issue described in: #856 (in progress).
