Applying the GraphQL schema to a message

When you are testing a GraphQL endpoint you can apply the GraphQL schema and other formatting options to messages in your tests.

Before you begin

You must have completed the following tasks:

Created an HTTP connection as a logical resource. See Creating logical HTTP connections.
Created a physical web server resource and bound it to the logical connection. See Creating physical web server resources.
Created a service component. See Creating a service component.
Created an operation. See Creating an operation.
Created tests by using message exchange pattern. See Creating a single test by using MEP. For example, you might have created a test for the Request-Reply MEP.
Opened the test in the Test Factory perspective that displays the test steps in the MEP test.

Procedure

Click the Send Request test step.

A message is displayed in the message editor.

Right-click text (String) in the Message field, and then click Schema.

The Schema Selector dialog is displayed.

You can select the schema from the following options:


Schema option	Action
GraphQL	Select this schema option if you want to use the built-in GraphQL schema either as the GraphQL mutation or GraphQL query operation type in the messages.
GraphQL Schema	Select this schema option if you have downloaded other GraphQL schemas and you do not want to use the built-in schemas.

Note: Both GraphQL schema options can be used to create messages that contain multiple queries or mutations.

Click the Schema Type field in the Schema Selector dialog, and then select the schema option as follows:
- Click Web > GraphQL to use the built-in GraphQL schema.
- Click Web > GraphQL Schema to use the GraphQL schema you have imported into Test Integrations and APIs.
The GraphQL schemas that you can apply to the message are displayed.

Select a GraphQL schema document from the list.

You can select from the following options:

mutationDocument

You can find the schemas that are applied when you select any of the document type as displayed in the following table:

Select GraphQL Payload if the message body is to be displayed and sent in the GraphQL format. Select Query Parameters if the content of the message is to be sent as URL encoded query parameters and the message body is empty.

Option	Description	Action
Retain existing content	When this option is selected, you can apply a schema or expand a field without losing the original data in the messages. When this option is not selected, existing data is cleared before the new schema is applied. In cases where the data is assumed to be retained, this option is not displayed.
