/**
* This class supports the implementation of Parser Tests in a standalone mode
* and without network access.
*
* In standalone mode, the config and data transformations needed by Parsoid
* cannot come from MediaWiki's database or its core classes.
*
* Without network access, we cannot fetch site configs or do data transformations
* on a remote wiki. This class supports this by intercepting network requests
* and returning mock responses based on cached site configs, hardcoded network
* responses and config,
*
* So, this API helper should be used with the Parsoid\Config\Api* set of config classes
* (and any subclasses derived from them).
*
* A lot of the responses here are tuned to what ParserTests needed. But, presumably
* this can be used by PHP Unit tests as long as the specific set of mocked responses
* satisfies the needs of those tests. Ideally, this class should NOT be updated for
* anything but the needs of running parser tests.
*
* Alternatively, PHP Unit tests could bypass the Api* classes altogether and use
* a (sub)set of mocked classes (Env, SiteConfig, PageConfig, DataAccess) if those
* classes and the data they provide satisfies the needs of those tests.
