Called runs accept deployment and credential inputs, derive target URLs, and check out the workflow repository and commit. Direct runs retain their existing behavior. The README documents this interface. ChangesReusable functional workflow
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to This change enables cross-repository functional-test execution and explicitly checks out the workflow source. If the calling repository cannot grant the required read access, the test job may fail before tests run; the PR is otherwise mergeable with explicit owner awareness of this bounded permission risk.

EduIDE-deployment's deploy-e2e.yml calls this workflow with an `environment` input and KEYCLOAK_USER / KEYCLOAK_PWD secrets, but the workflow declared only push and pull_request triggers. A call into a workflow with no workflow_call trigger fails while the run is being parsed, so every Deploy e2e run went red with no jobs listed at all. Add the workflow_call trigger with the input and secrets the caller actually sends, and derive LANDINGPAGE_URL from the input when called, falling back to vars.LANDINGPAGE_URL for this repository's own runs. In EduIDE-deployment the environment name under environments/ is the landing page hostname for every environment, so https://<environment> is the URL the Playwright suite expects. Checkout has to name the repository as well: inside a called workflow the github context describes the caller, so a bare checkout would clone EduIDE-deployment and there would be no test suite on disk.

`runs-on: [self-hosted, e2e-test]` matched no registered runner, so every run since 2026-08-27 15:13 sat queued - nine of them, including plain pushes to main on workflows nobody had touched. The repository has no self-hosted runners of its own, and the only ones in the organisation are two ARC scale sets on the student cluster (`arc-buildkit-*-stud-amd64`). An ARC scale-set runner is addressed by its scale set name and never carries the `self-hosted` label, so that label combination cannot ever match. `ubuntu-latest` is enough: the environments under test are reachable from the public internet, which Let's Encrypt proves every time it validates their certificates over HTTP-01, so the suite needs no cluster access. `ARTEMIS_URL` is now an optional `artemis_url` input, because different environments front different Artemis instances and the caller is the only thing that knows which. It falls back to the repository variable when the workflow is triggered directly, so existing behaviour is unchanged.

The bug
EduIDE/EduIDE-deployment/.github/workflows/deploy-e2e.ymlends its pipeline with:functional-tests.ymlonmaindeclared only:No
workflow_calltrigger, no inputs, no secret declarations. Auses:job pointing at a workflow that cannot be called fails while the run is being parsed, before any job is created.That matches what
Deploy e2ehas been doing: it failed on every push run - 22:04, 22:54, 23:50 and 03:10 on 2026-08-27 - each time with no jobs listed. A failing test suite produces a failed job; an unparseable workflow produces no jobs at all.What changed
.github/workflows/functional-tests.ymlAdded a
workflow_calltrigger declaring exactly what the caller sends: a requiredenvironmentstring input and requiredKEYCLOAK_USER/KEYCLOAK_PWDsecrets.pushandpull_requestare untouched, so this repository's own CI keeps running as before.LANDINGPAGE_URLnow comes from the input when called and fromvars.LANDINGPAGE_URLotherwise:The
inputscontext is empty forpush/pull_request, so direct runs take the old path unchanged.varsin a called workflow resolves against the caller's repository, which is why the fallback alone would not have worked - EduIDE-deployment has noLANDINGPAGE_URLvariable.ARTEMIS_USER/ARTEMIS_PWDare declared as optional secrets. A called workflow can only read secrets it declares, and the caller has no Artemis credentials. Thefunctionalproject matches*.functional.spec.tsand*.ide.spec.tsonly, so it never reaches the Artemis fixtures ortests/artemis/*.integration.spec.ts; leaving them empty for a called run is fine, and declaring them keeps direct runs identical.Checkout now names the repository explicitly. Inside a called workflow the
githubcontext describes the caller, soactions/checkoutwith norepository:would have cloned EduIDE-deployment andnpm ciwould have found nopackage.json. It uses GitHub's documented recipe for a reusable workflow checking out its own source, gated on the input so direct runs are byte-for-byte the old behaviour:README.mddocuments the reusable entry point, the meaning ofenvironment, and the optional Artemis secrets.Why
https://<environment>is the right URLThe Playwright suite consumes
LANDINGPAGE_URLas a full base URL -playwright.config.tsfeeds it tobaseURL,fixtures/utils/global-setup.tsthrows when it is unset, andfixtures/theia.fixture.tsnavigates to it directly. So the hostname input has to be turned into a URL.In EduIDE-deployment the landing page hostname is
values.yaml'shosts.configuration.landing + "." + baseHost, and that equals the directory name underenvironments/for all eight environments (e2e+eduide.student.k8s.aet.cit.tum.de=e2e.eduide.student.k8s.aet.cit.tum.de, and so on).deploy.ymlbuilds its own deployment URL the same way:echo "url=https://${{ steps.env.outputs.landing }}".Caller / callee contract, checked field by field
environmentenvironment(string, required)KEYCLOAK_USER,KEYCLOAK_PWDKEYCLOAK_USER(required),KEYCLOAK_PWD(required),ARTEMIS_USER(optional),ARTEMIS_PWD(optional)Every required input and secret is supplied, and the caller sends nothing the callee does not declare. Verified by reading both files with
yqrather than by eye.Validation
actionlint 1.7.12reports three things, all reviewed:label "e2e-test" is unknown- pre-existing, and the self-hosted runner label is deliberately unchanged. actionlint cannot know custom labels without anactionlint.yaml.property "workflow_repository" / "workflow_sha" is not defined in object typefor thejobcontext - actionlint's context model has not caught up. Both are documentedjobcontext properties and GitHub's docs use exactly this pair as the example of a reusable workflow checking out its own code.No other findings. The secret-related errors actionlint raised on an earlier draft (undeclared
ARTEMIS_*in a workflow with an explicitsecrets:block) are what led to declaring them as optional.Not verified here
runs-on: [self-hosted, e2e-test]means this PR's own functional run needs the self-hosted runner. The cross-repo call itself can only be proven by aDeploy e2erun in EduIDE-deployment after this merges.🤖 Generated with Claude Code
