Maven 3 Plugin API

 The API for Maven 3 plugins - composed of goals implemented by Mojos - development:

 * </p>
 *
 * @since 4.0.0
 */
@Experimental
@Immutable
public interface Artifact {
    /**
     * {@return a unique identifier for this artifact}
     * The identifier is composed of groupId, artifactId, extension, classifier, and version.
     *
     * @see ArtifactCoordinates#getId()
     */
    @Nonnull
    default String key() {
        String c = getClassifier();

and aggregate telemetry data. Istio's control plane provides an abstraction
layer over the underlying cluster management platform, such as Kubernetes.

Istio is composed of these components:

- **Envoy** - Sidecar proxies per microservice to handle ingress/egress traffic
   between services in the cluster and from a service to external

## Separating tests

In a real application, you probably would have your tests in a different file.

And your **FastAPI** application might also be composed of several files/modules, etc.

### **FastAPI** app file

Let's say you have a file structure as described in [Bigger Applications](bigger-applications.md){.internal-link target=_blank}:

```
.
├── app

    e.execute(runMe);
    fakePool.runAll();

    assertEquals(2, numCalls.get());
  }

  public void testInterrupt_beforeRunRestoresInterruption() throws Exception {
    // Run a task on the composed Executor that interrupts its thread (i.e. this thread).
    fakePool.execute(
        new Runnable() {
          @Override
          public void run() {
            Thread.currentThread().interrupt();
          }

    e.execute(runMe);
    fakePool.runAll();

    assertEquals(2, numCalls.get());
  }

  public void testInterrupt_beforeRunRestoresInterruption() throws Exception {
    // Run a task on the composed Executor that interrupts its thread (i.e. this thread).
    fakePool.execute(
        new Runnable() {
          @Override
          public void run() {
            Thread.currentThread().interrupt();
          }

The API docs use **Swagger UI** and **ReDoc**, and each of those need some JavaScript and CSS files.

By default, those files are served from a <abbr title="Content Delivery Network: A service, normally composed of several servers, that provides static files, like JavaScript and CSS. It's commonly used to serve those files from the server closer to the client, improving performance.">CDN</abbr>.

`OAuth2PasswordRequestForm` is a class dependency that declares a form body with:

* The `username`.
* The `password`.
* An optional `scope` field as a big string, composed of strings separated by spaces.
* An optional `grant_type`.

/// tip

The OAuth2 spec actually *requires* a field `grant_type` with a fixed value of `password`, but `OAuth2PasswordRequestForm` doesn't enforce it.
