Using Pipelines to run Detox Tests for iOS

Question & Answer Pipelines
1

Hello!

Has anyone set up the bitrise pipelines to run their Detox tests? I am having trouble building the app in one stage and then using the intermediate file to then run the tests on that build in a different stage.

My ideal pipeline would be
Stage 1 - Workflow 1 -Build the app
Stage 2 - Workflow 1 - Pull the app from stage 1, and run test suite 1
- Workflow 2- Pull the app from stage 1, and run test suite 2
- Workflow 3- Pull the app from stage 1, and run test suite 3
etc etc

But right now while I deploy the app in stage 1 workflow 1, it is not being picked up in stage 2 at all
Here is an excerpt from my bitrise.yml with the relevant workflows

pipelines:
  build-and-run-e2e-tests:
    stages:
    - build-ios: {}
    - test-ios: {}

  test-ios:
    workflows:
    - run-e2e-accountNavigation: {}
    - run-e2e-appNavigation: {}
workflows:
  e2e-test-ios-build:
      steps:
      - activate-ssh-key@4:
          run_if: '{{getenv "SSH_RSA_PRIVATE_KEY" | ne ""}}'
      - git-clone@8.2: {}

      - script@1:

              npx detox test -c ios.sim.debug.ci e2e/accountNavigation.test.ts --record-videos failing --artifacts-location ./artifacts/detox_artifacts/
      - deploy-to-bitrise-io@2:
          run_if: .IsBuildFailed
          is_always_run: true
          inputs:
          - is_compress: "true"
    run-e2e-appNavigation:
      steps:
      - pull-intermediate-files@1:
          inputs:
          - artifact_sources: build_ios.e2e-test-ios-build
      - script@1:
          inputs:
          - content: |-
              npx detox test -c ios.sim.debug.ci e2e/appNavigation.test.ts --record-videos failing --artifacts-location ./artifacts/detox_artifacts/
      - deploy-to-bitrise-io@2:

          is_always_run: true
          inputs:
          - is_compress: "true"

The output for the from the Pull Intermediate Files step is

Hi micahdasMA,

I believe there is a typo in YML:
The stage is build-ios and in the pull-intermediate-file there is build_ios as stage with an underscore and not a dash.
Would you try to fix that and see if the rest of it works?

Thank you! I caught that and am now able to pull the app in the subsequent stages by using the environment variable process.env.BITRISE_TEST_BUNDLE_PATH, as my binaryPath for the app in .detoxrc.js

I am now having some issues getting the app to launch however.

Here is the relevant workflow

  run-e2e-appNavigation:
    before_run:
    - _pull_test_bundle
    steps:
    - activate-ssh-key@4:
        run_if: '{{getenv "SSH_RSA_PRIVATE_KEY" | ne ""}}'
    - git-clone@8.2: {}
    - cache-pull@2: {}
    - script@1:
        inputs:
        - content: |-
            brew tap wix/brew
            brew install applesimutils
    - script@1:
        inputs:
        - content: npx detox rebuild-framework-cache && npx detox test -c ios.sim.debug.ci
            e2e/appNavigation.test.ts --record-videos failing --artifacts-location
            ./artifacts/detox_artifacts/
    - deploy-to-bitrise-io@2:
        run_if: ".IsBuildFailed"
        is_always_run: true
        inputs:
        - is_compress: 'true'

I was able to see using remote access that the simulator is launching, but I get the error No Bundle URL present

I tried adding a step before to run the script react-native run ios but it takes a long time and is basically doing what was already dont in the first stage to build the app so there are not really any time savings

hey micahdasMA were you able to resolve the issue with “No Bundle URL present” when caching your Detox builds on Bitrise as we are also using Detox on Bitrise and facing same issue ?
