This contains apparently enough changes to the current E2E test code to make it runnable against remote Kubernetes clusters. I was actually able to make the test passing against my AWS EKS based test clusters with these changes. You still need to trigger it manually from a local checkout of the ARC repo today. But this might be the foundation for automated E2E tests against major cloud providers.
* Cover ARC upgrade in E2E test
so that we can make it extra sure that you can upgrade the existing installation of ARC to the next and also (hopefully) it is backward-compatible, or at least it does not break immediately after upgrading.
* Consolidate E2E tests for RS and RD
* Fix E2E for RD to pass
* Add some comment in E2E for how to release disk consumed after dozens of test runs
Previously the E2E test suite covered only RunnerSet. This refactors the existing E2E test code to extract the common test structure into a `env` struct and its methods, and use it to write two very similar tests, one for RunnerSet and another for RunnerDeployment.
This enhances the E2E test suite introduced in #658 to also include the following steps:
- Install GitHub Actions workflow
- Trigger a workflow run via a git commit
- Verify the workflow run result
In the workflow, we use `kubectl create cm --from-literal` to create a configmap that contains an unique test ID. In the last step we obtain the configmap from within the E2E test and check the test ID to match the expected one.
To install a GitHub Actions workflow, we clone a GitHub repository denoted by the TEST_REPO envvar, progmatically generate a few files with some Go code, run `git-add`, `git-commit`, and then `git-push` to actually push the files to the repository. A single commit containing an updated workflow definition and an updated file seems to run a workflow derived to the definition introduced in the commit, which was a bit surpirising and useful behaviour.
At this point, the E2E test fully covers all the steps for a GitHub token based installation. We need to add scenarios for more deployment options, like GitHub App, RunnerDeployment, HRA, and so on. But each of them would worth another pull request.
This is the initial version of our E2E test suite which is currently a subset of the acceptance test suite reimplemented in Go.
To run it, pass `-run ^TestE2E$` to `go test`, without `-short`, like `go test -timeout 600s -run ^TestE2E$ github.com/actions-runner-controller/actions-runner-controller/test/e2e -v`.
`make test` is modified to pass `-short` to `go test` by default to skip E2E tests.
The biggest benefit of rewriting the acceptance test in Go turned out to be the fact that you can easily rerun each step- a go-test "subtest"- individually from your IDE, for faster turnaround. Both VS Code and IntelliJ IDEA/GoLand are known to work.
In the near future, we will add more steps to the suite, like actually git-comminting some Actions workflow and pushing some commit to trigger a workflow run, and verify the workflow and job run results, and finally run it on our `test` workflow to fully automated E2E testing. But that s another story.
