+## Fakes
+The `fake` package provides implementations for fake servers that can be used for testing.
+To create a fake server, declare an instance of the required fake server type(s).
+```go
+myFakeMetricsServer := fake.MetricsServer{}
+```
+Next, provide func implementations for the methods you wish to fake.
+The named return variables can be used to simplify return value construction.
+```go
+myFakeMetricsServer.List = func(ctx context.Context, resourceURI string, options *armmonitor.MetricsClientListOptions) (resp azfake.Responder[armmonitor.MetricsClientListResponse], errResp azfake.ErrorResponder) {
+	// TODO: resp.SetResponse(/* your fake armmonitor.MetricsClientListResponse response */)
+	return
+}
+```
+You connect the fake server to a client instance during construction through the optional transport.
+Use `NewTokenCredential()` from `azcore/fake` to obtain a fake credential.
+```go
+import azfake "github.com/Azure/azure-sdk-for-go/sdk/azcore/fake"
+client, err := armmonitor.NewClient("subscriptionID", azfake.NewTokenCredential(), &arm.ClientOptions{
+	ClientOptions: azcore.ClientOptions{
+		Transport: fake.NewMetricsServerTransport(&myFakeMetricsServer),
+	},
+})
+```
