GraphqlTester should not have web dependencies

[rstoyanchev]

There is nothing in GraphQlTester that is web specific, apart from the factory methods accepting WebTestClient and WebGraphqlHandler, but that'll change as we add web specific inputs for #64.

We can create a WebGraphQlTester that extends GraphQlTester, allows additional, web-specific inputs, and exposes web-specific factory methods, while GraphQlTester remains neutral to the underlying transport it is used with. In the future we may have other such extensions, for example for testing GraphQL requests over RSocket.

So there may be an additional GraphQL over RSocket and GraphQL over WebSocket implementations as alternatives of the existing GraphQL over HTTP in Spring GraphQL?

[rstoyanchev]

Yes exactly. Even what we have at the moment is flexible to execute with or without an HTTP client, but this would more formally separate Web (HTTP, WebSocket) from other transports like RSocket.
