#SpringBootTest mark #Configuration using main class - spring-boot

Question

I have a spring boot app with following structure:
App.java
#SpringBootApplication(exclude = { ErrorMvcAutoConfiguration.class })
#ComponentScan(basePackages = "com.mergg.webapp.config")
public class App extends SpringBootServletInitializer{
public static void main(final String... args) {
new SpringApplicationBuilder(App.class)
.initializers(new MyApplicationContextInitializer())
.run(args);
}
}
Here you can see that I am loading classes marked with #Configuration via component scan. These files are used to create beans and build an ApplicationContext
I am trying to configure integration tests with such structure:
#RunWith(SpringRunner.class)
#SpringBootTest(classes = App.class)
public class SpringBootIntegrationTest {
#Test
public void whenSpringContextLoaded_thenNoExceptions() {
}
}
When this test runs I get
java.lang.IllegalStateException: Failed to load ApplicationContext
How can I configure the tests to load the ApplicationContext with this structure? I know i can use the classes variable that is part of the #SpringBootTest but I feel like this does not scale well as I add more #Configuration classes. Is there a way to do it more concisely and managed?

Please note that I added #PropertySource({ "classpath:${envTarget:local-dev}.properties" }) in both my integration test and in my App.class (even though App.java does not use that property file directly (other configuration classes use it but they already have that annotation in that class directly)
EDIT 2
All my property files are in /src/main/resources
