GraphQLTestTemplate is not injected at all

[khteh]

Describe the bug
I am trying to test my GraphQL query with GraphQLTestTemplate. Here is my test class:

@GraphQLTest
public class GraphQLApplicationTests {
	@Autowired
    private GraphQLTestTemplate graphQLTestTemplate;	
	@Test
    public void GetAllBooks_Succeed() throws IOException {
		assertNotNull(graphQLTestTemplate);
        GraphQLResponse response = graphQLTestTemplate.postForResource("graphql/get-all-books.graphql");
        assertNotNull(response);
        assertTrue(response.isOk());
        // bookRepository.save(new Book("My First GrapQL Book", "1234567890", 500, author));
        assertEquals("My First GrapQL Book", response.get("$.data.book.title"));
        assertEquals("1234567890", response.get("$.data.book.isbn"));
        assertEquals(500, response.get("$.data.book.pageCount"));
        assertNotNull("$.data.book.author");
    }
}

pom.xml:

		<dependency>
		    <groupId>com.graphql-java-kickstart</groupId>
		    <artifactId>graphql-spring-boot-starter-test</artifactId>
		    <version>7.0.1</version>
		</dependency>

mvn test fails the first assertion: assertNotNull(graphQLTestTemplate);

Besides, running it with mvn spring-boot:run bumps into the following runtime exception:

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.

Does it work if you are using @SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT) instead of @GraphQLTest? (I hardly ever used @GraphQLTest to run integration tests).

(Btw. I think the dependency should have <scope>test</scope>)

[khteh]

No, it is still NULL using SpringBootTest.Yes, I missed out the <scope>test</scope>

[BlasiusSecundus]

At least the spring-boot run issue should have been resolved by adding the test scope.

From the code provided here I have no more ideas, maybe it is related to maven setup?

[khteh]

Which maven setup is suspicious of causing the error?

[BlasiusSecundus]

That was just an idea, the cause is perhaps something different. I don't have any specific suspicion.

I am facing the same error.
Upon injecting

@Autowired
private GraphQLTestTemplate graphqlTestTemplate;

IntelliJ complains: Could not autowire. No beans of 'GraphQLTestTemplate' type found..
Upon running the test, I get NullPointerException for graphqlTestTemplate.

<dependency>
        <groupId>com.graphql-java-kickstart</groupId>
        <artifactId>graphql-spring-boot-starter-test</artifactId>
        <version>7.0.1</version>
        <scope>test</scope>
</dependency>

I tried using @SpringBootTest instead of @GraphQLTest but still its the same error.

Does anyone have an idea about this?

[ubarua123]

Yeah I am facing the same.

@RunWith(SpringRunner::class)
@GraphQLTest
internal class QueryResolverTest {

    @Autowired
    private lateinit var graphQLTestTemplate: GraphQLTestTemplate


    @Test
    fun testFoo() {

    }
}

Could not autowire. I noticed there is no @Component or @Bean annotation on the GraphQLTestTemplate class. Maybe that's why? So how is it being declared as a bean.

[BlasiusSecundus]

The bean is defined here: https://github.com/graphql-java-kickstart/graphql-spring-boot/blob/master/graphql-spring-boot-test-autoconfigure/src/main/java/com/graphql/spring/boot/test/GraphQLTestAutoConfiguration.java

[jeet23]

Ok, so I removed @GraphQLTest and I am using

@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)

Even though IntelliJ complains, the graphqlTestTemplate bean is actually injected on application startup.

I played around with it as well, following @jeet23's comment worked for me. Thanks!

@Autowired
private GraphQLTestTemplate graphQLTestTemplate;

@MockBean
private ResourceService resourceServiceMock;

@Test
public void getResourceById() throws IOException {
    Resource resource = new Resource(1L, "Facebook", "facebook.com");
    when(resourceServiceMock.getResource(any())).thenReturn(resource);
    GraphQLResponse response = graphQLTestTemplate.postForResource("graphql/get-resource-by-id.graphql");
    assertTrue(response.isOk());

    assertEquals("1", response.get("$.data.resource.id"));
    assertEquals("Facebook", response.get("$.data.resource.title"));
    assertEquals("facebook.com", response.get("$.data.resource.url"));
}
