/**
 * @see https://github.com/SemanticMediaWiki/SemanticMediaWiki/tree/master/tests#write-integration-tests-using-json-script
 *
 * `JsonTestCaseScriptRunner` provisioned by SMW is a base class allowing to use a JSON
 * format to create test definitions with the objective to compose "real" content
 * and test integration with MediaWiki, Semantic MediaWiki, and Scribunto.
 *
 * The focus is on describing test definitions with its content and specify assertions
 * to control the expected base line.
 *
 * `JsonTestCaseScriptRunner` will handle the tearDown process and ensures that no test
 * data are leaked into a production system but requires an active DB connection.
