Integration Test Framework
The integration test framework for Antrea multi-cluster is mainly using envtest
which is provided by controller-runtime
. There is an online book
about kubebuilder that describes a few steps about how to configure envtest
for integration tests. envtest
supports using an existing cluster to run integration
test by setting a config USE_EXISTING_CLUSTER
. In Antrea multi-cluster, we choose to use
an existing cluster to run tests with a real control plane and dependent controllers
like Service, Endpoints controllers etc.
Running the Antrea Multi-cluster Integration tests
The tests must be run on an real Kubernetes cluster. At the moment, you can
simply run make test-integration
in antrea/multicluster
folder. It will
create a Kind cluster named antrea-integration-kind
and execute the integration
codes.
if you'd like to run the integration test in an existing Kubernetes cluster, you
can save your kubeconfig file as mc-integration-kubeconfig
in /tmp
directly,
the integration test codes will read the file /tmp/mc-integration-kubeconfig
by
default, then run below commands:
export KUBECONFIG=/tmp/mc-integration-kubeconfig
kubectl create namespace leader-ns
kubectl apply -f test/integration/cluster-admin.yml
go test -coverpkg=antrea.io/antrea/multicluster/controllers/multicluster/... -coverprofile=../.coverage/coverage-integration.txt -covermode=atomic -cover antrea.io/antrea/multicluster/test/integration/...
You should be able to see the overall results from terminal, if you'd like to
check more details, you can go check the file .coverage/coverage-integration.txt
