-<p>Webtau follows GraphQL's https://graphql.org/learn/serving-over-http/ Serving over HTTP best practices when invoking GraphQL servers over HTTP.It therefore assumes the server responds to requests to /graphql so you do not need to specify that in the URL in your configuration. Requests allow providing:a query/mutation string variables an operation name Webtau will default to issuing POST requests according to the https://graphql.org/learn/serving-over-http/#post-request best practices and will expect a 200 status code and a response with a data or errors field.The following example demonstrates most of these query features: package scenarios.graphql import static org.testingisdocumenting.webtau.WebTauGroovyDsl.* def listAllQuery = ''' { allTasks(uncompletedOnly: false) { id description } } ''' def taskByIdQuery = ''' query taskById($id: ID!) { taskById(id: $id) { id description completed } } ''' def completeMutation = ''' mutation complete($id: ID!) { complete(id: $id) } ''' scenario("list all tasks") { graphql.execute(listAllQuery) { // Execute a simple query with no variables errors.should == null // Validate there were no errors body.data.allTasks.id.should == ["a", "b", "c"] // Access response data with the full path allTasks.id.should == ["a", "b", "c"] // Access response data via a shortcut allowing omitting of `body.data` id.should == ["a", "b", "c"] // For single query requests, access response data via a shortcut allowing omitting of `body.data` and the query name } } scenario("complete a task") { graphql.execute(completeMutation, [id: "a"]) { // Execute a mutation with a variables map errors.should == null complete.should == true } graphql.execute(taskByIdQuery, [id: "a"]) { errors.should == null taskById.id.should == "a" taskById.completed.should == true } } scenario("cannot complete a completed task") { graphql.execute(completeMutation, [id: "b"]) { // Execute a mutation with a variables map errors.should == null complete.should == true } graphql.execute(completeMutation, [id: "b"]) { // force an error errors[0].message.shouldNot == null complete.should == null } }</p>
