### JavaDoc Requirements

All public classes and methods require JavaDoc with `@param`, `@return`, and `@throws` tags.

### Best Practices

**Null Safety:**
```java
public Suggester(final Client client, final SuggestSettings settings) {

   * exceptions thrown from the test do not cause this check to fail.
   */
  @RegisterExtension
  val noDataLeftBehind =
    AfterEachCallback { context: ExtensionContext ->
      if (context.executionException.isPresent) return@AfterEachCallback
      assertThat(data.readByteString().hex(), "Data not empty")
        .isEqualTo("")
    }

  // Mutually exclusive. Use the one corresponding to the peer whose behavior you wish to test.

│   ├── main.py
│   └── test_main.py
```

Let's say that now the file `main.py` with your **FastAPI** app has some other **path operations**.

It has a `GET` operation that could return an error.

It has a `POST` operation that could return several errors.

Both *path operations* require an `X-Token` header.
