How do I create a unittest for a servicelayer which uses the client?

[MartijnStraatman]

How do I mock the client in a proper way so I can unittest my dependent services?

For example

    private MixedOperation<io.clastix.capsule.v1beta1.Tenant,
    KubernetesResourceList<io.clastix.capsule.v1beta1.Tenant>, Resource<io.clastix.capsule.v1beta1.Tenant>> tenantClient() {
        return  kubernetesClient.resources(io.clastix.capsule.v1beta1.Tenant.class);
    }

If I call tenantClient I want to mock a response. For example a Tenant Resource or a list for resources?

I tried several things with Mockito. Maybe someone can help me a bit?

@MartijnStraatman : Have you tried Fabric8 Kubernetes Mock Server? You can see an example of mocking custom resource call here.

There is also an option of setting up test etcd/kubernetes apiserver environment using jenvtest . See blogpost

I did. The CRD's I am using is not something I have created myself. I am just wondering how I can test my own service logic against the kubernetes responses. So how can I intregrate the Fabric8 Kubernetes Mock Server in my unittest as the service layer will use that Mock Server?

You can read my blogpost to get some idea about this How to write tests with Fabric8 Kubernetes Client

Thx, worked!

Sorry, I didn't understand your question properly. What do you mean by this?
