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()
    .addHeader("Content-Type", "application/json; charset=utf-8")
    .addHeader("Cache-Control", "no-cache")
    .setBody("{}");
```

MockResponse can be used to simulate a slow network. This is useful for
testing timeouts and interactive testing.

```java

        for (File sourceFile : vsProject.getSourceFiles()) {
            filtersFile.addSource(sourceFile);
        }

        for (File headerFile : vsProject.getHeaderFiles()) {
            filtersFile.addHeader(headerFile);
        }

        for (Action<? super XmlProvider> xmlAction : vsProject.getFiltersFile().getXmlActions()) {
            getXmlTransformer().addAction(xmlAction);
        }
    }
