Your unit tests might move the `server` into a field so you can shut it down
from your test's `tearDown()`.

### API

#### MockResponse

Mock responses default to an empty response body and a `200` status code.
You can set a custom body with a string, input stream or byte array. Also
add headers with a fluent builder API.

```java
MockResponse response = new MockResponse()

    @Override
    protected OptionalThing<String> getCookieRememberMeKey() {
        // example to use remember-me
        //return OptionalThing.of(fessConfig.getCookieRememberMeFessKey());
        return OptionalThing.empty();
    }

    @Override
    protected void saveLoginHistory(final FessUser user, final FessUserBean userBean, final LoginSpecifiedOption option) {
        asyncManager.async(() -> {
            insertLogin(user);
