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
make test-integration in
antrea/multicluster folder. It will
create a Kind cluster named
antrea-integration and execute the integration
if you'd like to run the integration test in an existing Kubernetes cluster, you
can save your kubeconfig file as
the integration test codes will read the file
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
