Detox: Error: Detox version 0.57 android

[krupanandkk]

I am getting "Couldn't find preset "module:metro-react-native-babel-preset" relative to directory" error. I am using react native version 0.57. And while testing I am getting this error.

IMPORTANT: And I have doubt how to run generated apk file using detox without running build command.

Detox is for iOS only. No support for future Android versions https://github.com/wix/detox/issues/608

[rotemmiz]

Detox is not for iOS only. It is supported on Android, we use it in multiple projects internally, and alos on other open source projects.
React native Navigation: https://jenkins-oss.wixpress.com/job/rnn-android-master/100/console
Detox's CI: https://jenkins-oss.wixpress.com/job/detox-android-56-master/

Official supported versions are here: https://github.com/wix/detox/blob/master/README.md#supported-react-native-versions

There is no issue we know about in RN57 on iOS, the e2e suite passes.
on Android, there's an issue with scroll actions on RN57, a fix is pending, and basically, that's the reason why the readme still states otherwise.

If you don't know an answer to a question, please do not give false information.

[rotemmiz]

Regarding the original question, it seems to be a compilation issue, and I think it's quite popular with projects who upgraded to RN57. Are you running Detox with Jest? Your configuration might be broken. I would also guess that if you'd run the same test with no Detox code in your tests, you will get the same error.

[dbanck]

I'm having the same issue.

Steps to reproduce:

1. Create a new react native app with react-native init
2. Run the app and see the welcome screen without any problems
3. Add detox as described in the introduction and run detox build
4. Running detox test will fail with the following output:

$ detox test

Now, while keeping the RN packager running, remove the following line from the .babelrc:

  "presets": ["module:metro-react-native-babel-preset"]

When I now run detox test the tests are working and passing.

If I make any changes to the JS code, I need to re-add the line to the .babelrc since the RN package can't recompile the code without it.

Edit 1
Might be related to https://github.com/facebook/metro/issues/242 and https://github.com/facebook/react-native/issues/21241

Edit 2
Updating the e2e/config.json with the following content works for now:

{
    "setupTestFrameworkScriptFile": "./init.js",
    "testEnvironment": "node",
    "transform": {
        "^.+\\.js$": "<rootDir>/../node_modules/react-native/jest/preprocessor.js"
    }
}
