GraphQLTestSubscription fails to init() when using @GraphQLTest

[lassemaatta]

Describe the bug

GraphQLTestSubscription fails to create a WebSocket connection in a test.

To Reproduce Steps to reproduce the behavior:

1. Define a test class annotated with @GraphQLTest
2. Autowire the GraphQLTestSubscription dependency
3. call init() on the test subcription
4. See error:

Caused by: javax.websocket.DeploymentException: The HTTP response from the server [404] did not permit the HTTP upgrade to WebSocket
	at org.apache.tomcat.websocket.WsWebSocketContainer.connectToServerRecursive(WsWebSocketContainer.java:440)
	at org.apache.tomcat.websocket.WsWebSocketContainer.connectToServer(WsWebSocketContainer.java:197)
	at com.graphql.spring.boot.test.GraphQLTestSubscription.initClient(GraphQLTestSubscription.java:387)

Expected behavior GraphQLTestSubscription should establish the WebSocket connection without errors.

Additional context I did notice that @GraphQLTest does not seem to include GraphQLWebsocketAutoConfiguration. However, importing it to the test context did not seem to fix the issue.

Until this is fixed, you can use @SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT) instead of @GraphQLTest

[BlasiusSecundus]

I could reproduce the issue with integration test. It seems that some necesary beans are missing when using @GraphQLTest, even if GraphQLWebsocketAutoConfiguration is added.

Number of beans

• when using @GraphQLTest - 100 ❌
• when using @GraphQLTest with GraphQLWebsocketAutoConfiguration added - 106 ❌
• when using @SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT) - 277 ✔️
