Profile properties not loading during integration tests

I’m trying to create some integration tests which run my Spring Boot application with a specified Spring profile. From my experimentation, it seems that I can set the profile, but Spring Boot does not load the properties file for that profile

@SpringApplicationConfiguration(classes = MyApplication.class, initializers = MyInitializer.class)
@WebIntegrationTest
@Stepwise
class MySpec extends Specification
{
}

class MyInitializer implements ApplicationContextInitializer<ConfigurableApplicationContext>
{
    @Override
    void initialize(ConfigurableApplicationContext applicationContext)
    {
        applicationContext.getEnvironment().setActiveProfiles('test')
    }
}

Using the debugger I can see that the Spring Environment object does have my active profile. But, the properties for my profile are not loaded.

To clarify, by properties file, I mean files in resources like: application.properties application-test.properties

I’ve tried this in Spring Boot 1.2.3 and 1.2.4. I am building with Gradle and testing with Spock.

I changed my integration test to:

@ContextConfiguration(loader = SpringApplicationContextLoader.class, classes = MyApplication.class)
@ActiveProfiles("development")
@WebIntegrationTest
@Stepwise
class MySpec extends Specification

I ran the application through the debugger and inspecting an @Autowired Environment I see the active profile development (it appears that there was an existing test so I changed my profile name). However, the profile properties are not being loaded for classes that need them.

I created a sample project, but was unable to reproduce the problem. Previously I had been running my tests from IntelliJ. I am now doing it from the Gradle build and it works. Oddly enough, in the sample project the tests do run from IntelliJ. So the issue here probably lies in IntelliJ.
