Spring Boot can't run single test in IntelliJ

Question

This started happening recently, but I'm not sure what changed to cause it.

• When I run all tests from IntelliJ, all is well. Also the gradle build is fine.
• When I run a single unit test, all is well.
• When I run a single web integration test, it fails because a config class has all null properties.

The config class looks like (Kotlin):

@Component
@ConfigurationProperties(prefix = "api")
public open class ApiConfigImpl : ApiConfig
{ 

A test looks like:

@RunWith(SpringJUnit4ClassRunner::class)
@ContextConfiguration(classes = arrayOf(ApplicationAssembly::class), loader = SpringApplicationContextLoader::class)
@WebIntegrationTest
open class CandidateProfileControllerTest
{

    @Inject lateinit var profileRepo: CandidateProfileRepository
    //etc a few more deps used to setup test data

    @Test
    open fun getById()
    {
        val greg = CandidateProfile("123", "12312", "Greg", "Jones",   dateOfBirth = Date(), gender = Gender.MALE,
            biography = "ABC", maxMatchableAge = null,   maxMatchableDistance = null)
        profileRepo.save(greg)

        val auth = given().header("content-type", "application/json")
            .body(testCredentials)
            .post("/authorization/social").peek().asString()
        val accessToken: String = from(auth).get("accessToken")

        given().header("Access-Token", accessToken).
            header("API-Key", testAPIKey()).
            get("/profile/${greg.id}").
            peek().then().
            body("stageName", notNullValue())
    }

I'm not sure what information I can add. Based on the limited information provided:

• Is this a known problem with a known solution?
