"No devices are connected" when running a Flutter integration test

[mregnauld]

In my workflow, I want to run integration tests for my Flutter app, by running those scripts:

- name: Install pods
  script: |
    find . -name "Podfile" -execdir pod install \;
- name: Integration tests iOS
  script: |
    flutter emulators --launch apple_ios_simulator
    flutter -d iPhone test --machine > test-results/flutter.json integration_test --flavor free
  test_report: test-results/flutter.json

But for some reason, I got the following error:

No devices are connected. Ensure that `flutter doctor` shows at least one connected device

Build failed :|
Step 7 script `Integration tests iOS` exited with status code 1

What did I do wrong?

Thanks.

Checking

OK so after refreshing my page, the script actually crashed 30 minutes ago.

Also, it seems that it didn't work because of what I can see in the log: Invalid runtime: com.apple.CoreSimulator.SimRuntime.iOS-15-5, which seems normal since I can't see iOS 15.5 in the available iOS versions.
So I'll try with another version.

If you see the build, it failed the integration test steps with an error in 14s.
Could not find a command named "integration_test".

Maybe the UI Froze. Please refresh the page.

Please replace it with the appropriate test name from your flutter project.

what i shared was for reference purposes com.apple.CoreSimulator.SimRuntime.iOS-15-5
You can run the command xcrun simctl list, select the simulator, and replace it in the script.

OK so we're back to the original error: CocoaPods not installed or not in valid state.
Build ID: 63c7c75d749e3517e38e3e56

Also, I used integration_test for my integration tests for Android (since all my integration tests are in the integration_test directory), and it works perfectly...

Hi @mregnauld, The error is at install pods step as below.

Invalid `Podfile` file: /Users/builder/clone/ios/Flutter/Generated.xcconfig must exist. If you're running pod install manually, make sure flutter pub get is executed first.

You are missing the script flutter pub get
i suggest cross-checking your workflow once with one of our sample repo here and then re-run the build.

Let us know how it goes.

OK so this finally worked:

- name: Install pods
  script: |
    flutter pub get
    find . -name "Podfile" -execdir pod install \;
- name: Integration tests iOS
  script: |
    xcrun simctl shutdown all
    TEST_DEVICE=$(xcrun simctl create test-device com.apple.CoreSimulator.SimDeviceType.iPhone-11 com.apple.CoreSimulator.SimRuntime.iOS-16-2)
    xcrun simctl boot $TEST_DEVICE
    flutter -d $TEST_DEVICE test integration_test --flavor free

Also, very important, it works only if I use cocoapods: 1.11.3, and not cocoapods: 1.9.1.

Thanks @himesh-cm for your help!
