Can't run detox tests for the iOS native app

[katnem]

Description

I'm trying to run the detox tests for the example native iOS app and getting the following:
Error: Cannot find module 'babel-polyfill' ... Error: Command failed: node_modules/.bin/mocha e2e --opts e2e/mocha.opts --configuration ios.sim.release ...
I've installed the 'babel-polyfill', but now getting similar error for module 'npmlog'. Installing that module didn't help.

Node, Device, Xcode and macOS Versions

• Node: v8.4.0
• Device: iphone 7 plus (iOS 10.3)
• Xcode: 8.3.3
• macOS: 10.12.6

Our demo projects have not been maintained in quite a while, sadly. We will have to fix them at some point. Thanks for your report.

In the mean time, you can test it on your own app by following the documentation.

Hi @LeoNatan, I've browsed through the docs and didn't find any mention of dealing with native iOS apps. Say, if I'm managing dependencies via cocoapods, I can't even build with detox (CompileSwiftSources fails when external libs are encountered, e.g. Alamofire).
Is there any documentation I've missed?

@rotemmiz Can you please assist here? Thanks

@katnem Ifnypu have a native project, you shouldn’t bring Detox with CocoaPods. Build your project as you normally do. You should bring Detox using npm or yarn.

[LeoNatan]

Please know there is an active issue with swift which we intend to solve really soon.

[katnem]

@LeoNatan Yeah, I meant for the native stuff I use cocoapods and npm for detox. What I meant by building with detox was this: detox build --configuration ios.sim.release

[LeoNatan]

Are you sure you have provided the correct build command in package json? E.g, with CocoaPods, you should build the workspace and not just the project.

[katnem]

Right, I was building the project rather than workspace, so now able to build. No luck with the test bit (detox test --configuration ios.sim.release) though (same issue as described at the very beginning). My structure within e2e dir looks like this:
PageObjects init.js my_test.spec.js mocha.opts

[LeoNatan]

@katnem Hey, were you able to resolve your issue? Our Swift issue has been fixed since a while ago. Please try again.

Hi @LeoNatan , unfortunately, I don't have my old setup anymore to verify the issue. However, I've tried to run the tests for the example project that you have
[https://github.com/wix/detox/tree/master/examples/demo-native-ios] and have the same issue when running tests:
`detox test --configuration ios.sim.release
node_modules/.bin/mocha e2e --opts e2e/mocha.opts --configuration ios.sim.release
module.js:491
throw err;

Hey @katnem, I had the same issue, but it's already fixed by adding babel-polyfill. I did not get npmlog error.

Environment details:
Node: v8.0.0 ( which I think you give it try )
Device: iphone 7 (iOS 11.1)
Xcode: 9.1
macOS: 10.12.6

(EDIT)

• I realized that I was able to run the test of this exmple: detox/examples/demo-react-native

• For detox/test example I got npmlog error. same issue here.

Thanks guys. I will close this issue for now. Feel free to open a new issue if you hit this. I am still not sure whether a Detox issue or an environment mishap.
