Interface DgsQueryExecutor

public interface DgsQueryExecutor

Represents the core query executing capability of the framework. Use this interface to easily execute GraphQL queries, without using the HTTP endpoint. This is meant to be used in tests, and is also used internally in the framework. The executeAnd* methods use the JsonPath library library to easily get specific fields out of a nested Json structure. The executeAndGetDocumentContext(String) method sets up a DocumentContext, which can then be reused to get multiple fields.
