Registration of Kubernetes API objects

Definition of terms: API Object - This is anything that a Kubernetes cluster would know about, examples are Pods, Deployments, Services, DeploymentLists. It can be extended by Custom Resource Definitions (CRDs) GroupVersionKind (GVK) - This is the identifier of an API Object. eg Core/V1/Pod GroupVersionResource (GVR) - This is an identifier for one particular GVK pods.core.v1 Schema - This is an object that understands how to translate a Go struct into the GroupVersionKind for the API object that struct represents and back. This is used in the encoding and decoding process.

When you use Kubernetes types in a go program you will import somthing like "k8s.io/apimachinery/pkg/apis/core/v1". In that package it will have something to register that API's known types. This SchemaBuilder, and the schemas from other types are used by the kubernetes client (and th

- "go.opentelemetry.io/otel/sdk/metric/number"
sdk/metric/sdkinstrument
- "go.opentelemetry.io/otel/sdk/metric/number"
sdk/metric/aggregator/aggregation
- "go.opentelemetry.io/otel/sdk/metric/number"
- "go.opentelemetry.io/otel/sdk/metric/sdkinstrument"
sdk/metric/aggregator
"go.opentelemetry.io/otel/sdk/metric/aggregator/aggregation"

This is an example of how test data compares when using different levels of metricdatatest.AssertEqual.

Asserting at the `Metrics` level

var tt.want metricsdata.Metrics
var rm metricsdata.ResourceMetrics // This was from Collect()

require.Len(t, rm.ScopeMetrics, 1)
sm := rm.ScopeMetrics[0]

Metric Test Cases

This is a list of language independent test cases to help validate an SDK's behavior. It's intended to enumerate some of the interactions of different parts of the specification.
