E2E tests

The directory contains E2E tests and test applications. Tests assume that Argo CD services are installed into argocd-e2e namespace or cluster in current context. One throw-away namespace argocd-e2e*** is created prior to tests execute. The throw-away namespace is used as a target namespace for test applications.

The test/e2e/testdata directory contains various Argo CD applications. Before test execution directory is copies into /tmp/argocd-e2e*** temp directory and used in tests as a git repository via file url: file:///tmp/argocd-e2e***.

Use the following steps to run tests locally:

1. (Do it once) Create namespace argocd-e2e and apply base manifests: kubectl create ns -n argocd-e2e && kustomize build test/manifests/base | kubectl apply -n argocd-e2e -f -
2. Change kubectl context namespace to argocd-e2e and start services using goreman start
3. Keep Argo CD services running and run tests using make test-e2e

The tests are executed by Argo Workflow defined at .argo-ci/ci.yaml. CI job The build argo cd image, deploy argo cd components into throw-away kubernetes cluster provisioned using k3s and run e2e tests against it.
