Use MockWebServer the same way that you use mocking frameworks like
[Mockito](https://github.com/mockito/mockito):

1. Script the mocks.
2. Run application code.
3. Verify that the expected requests were made.

Here's a complete example:

### Java
```java
public void test() throws Exception {
  // Create a MockWebServer. These are lean enough that you can create a new
  // instance for every unit test.

    /**
     * Initializes the RelatedContentHelper by loading related content configurations
     * from the data store. This method is called automatically after dependency
     * injection is complete.
     *
     * PostConstruct annotation ensures this method is called after the bean
     * has been constructed and all dependencies have been injected.
     */
    @PostConstruct
    public void init() {

class Dispatcher() {

   * remain in flight.
