subscription integration test fails with web starter

[Thinkenterprise]

I wrote the following test

@SpringBootTest(webEnvironment = WebEnvironment.RANDOM_PORT)
public class TestWebRouteSubscription {

    @Value("ws://localhost:${local.server.port}${spring.graphql.websocket.path}")
    private String baseUrl;

    @Autowired
    private GraphQlTester webGraphQlTester;

    @BeforeEach
    void setUp() {
        URI url = URI.create(baseUrl);
        this.webGraphQlTester = WebSocketGraphQlTester.builder(url, new ReactorNettyWebSocketClient()).build();
    }

    @Test
    @DisplayName("Test register Route Creted Subscription")
    public void registerRouteCreated() {

        Flux<Route> result = webGraphQlTester.documentName("registerRouteCreated").executeSubscription()
                .toFlux("registerRouteCreated", Route.class);
        StepVerifier verifier = StepVerifier.create(result).expectNextCount(1L).thenCancel().verifyLater();
        webGraphQlTester.documentName("createRoute").variable("flightNumber", "LH7977").execute()
                .path("createRoute.flightNumber").entity(String.class).isEqualTo("LH7977");

        verifier.verify();
    }
}

For the test I have the following dependency active

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-webflux</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-graphql</artifactId>

        </dependency>
        <dependency>
            <groupId>org.springframework.graphql</groupId>
            <artifactId>spring-graphql-test</artifactId>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-webflux</artifactId>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>io.projectreactor</groupId>
            <artifactId>reactor-test</artifactId>
            <scope>test</scope>
        </dependency>

In this setting, the test runs and works!!

If I change the first dependency from

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-webflux</artifactId>
</dependency>

to

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>

the test fails. The error message is:

org.springframework.graphql.client.GraphQlTransportException: GraphQlTransport error: Invalid handshake response getStatus: 405 ; nested exception is io.netty.handler.codec.http.websocketx.WebSocketClientHandshakeException: Invalid handshake response getStatus: 405 

In both cases web and weblux a websocket configuration is active? I cant understand this problem?

spring-boot-starter-webflux has both HTTP and WebSocket support, whereas spring-boot-starter-web only ships HTTP support. What happens if you also add spring-boot-starter-websocket to your application?

[Thinkenterprise]

Yes of course you were right. I opened the issue too quickly, sorry

[bclozel]

No worries, thanks for testing before the release, this is helping!

@Thinkenterprise do you mind explaining what the problem was and what you did to solve it? Mostly for people like me who come here with the exact same setup and issue but don't have the same understanding?

I am using the following dependencies, including web in place of webflux (except for testing) but I DO include spring-boot-starter-websocket and -security and yet I still receive error like you generated it, originally using web.
