[Internal] Skip integration tests on docs-only changes

[mgyucht]

Changes

Currently, integration tests run on every PR. This takes a considerable amount of time, up to around an hour and 15 minutes. When a change only affects the docs/ directory, there is no need to run integration tests, as that directory only includes the public documentation and user guides. Thus, integration tests can be skipped.

Tests

• make test run locally
• relevant change in docs/ folder
• covered with integration tests in internal/acceptance
• relevant acceptance tests are passing
• using Go SDK

There is an action to that does the grep for you.

      - uses: dorny/paths-filter@v3
        id: changes
        with:
          filters: |
            integration_tests_required:
              - '**/*'
              - '!docs/**'

needs: [changes]
if: '{{ needs.changes.outputs.integration_tests_required == "true" }}'

Actually, this won't work in the merge queue. If the "need" job is skipped, this will be skipped too (even with the "if" condition). You can use always() to ensure it runs. Also, use the output
if: always() && (github.event_name == 'merge_group' || needs.check-integration-test-changes.outputs.integration_tests_required == 'true')

It's an output, not an env.
Define the output and set an id for the job

jobs:
  changes:
    runs-on: ubuntu-latest
    outputs:  <----
      integration_tests_required: ${{ steps.filter.outputs.integration_tests_required }}
    steps:
      - uses: actions/checkout@v4
      
      - uses: dorny/paths-filter@v3
        id: filter <----
        with:
          filters: |
            integration_tests_required:
              - '!**/*.md'
