Hello,

I apologize in advance if my question is too basic. Are there any examples for using [Client mock](https://github.com/temporalio/sdk-go/blob/master/mocks/Client.go)? Specifically for setting custom return values and errors of the workflow when using `we.Get`?

```auto
we = client.GetWorkflow(workflowID)
var result interface{}
we.Get(ctx, &result)

```

Thanks.

You don’t really need to use the mocks package (we are considering removing it, see [Remove mocks package · Issue #61 · temporalio/sdk-go · GitHub](https://github.com/temporalio/sdk-go/issues/61)). Rather, it’s just an interface, use whatever your favorite approach is to mock an interface, be that a mocking lib you are used to or just impl the interface directly. For example (untested):

```nohighlight
type fakeClient struct { client.Client }

func (fakeClient) GetWorkflow(context.Context, string, string) client.WorkflowRun {
  return fakeWorkflowRun{}
}

type fakeWorkflowRun struct { client.WorkflowRun }

func (fakeWorkflowRun) Get(context.Context, interface{}) error {
  // Do whatever you want
  return nil
}

```
