How to get spring context or bean statically in tests?

Question

I know i can @Autowire spring context or any bean in my test classes. But is there any way to get the currently used context statically?

@SpringBootTest
class MyTest {

  @Autowire var applicationContext: ApplicationContext? // that's NOT what i want

  @Test
  fun myTest() {
    val result = HelperClass.staticFunction()
  }
}

and then:

class HelperClass {

  static public MyObject staticFunction( {
    return Some_spring_or_junit_static_class. 
           getCurrentSpringContextOrBean(nameOfBean)
  }
}

spring caches its contexs while running multiple tests. but is there any way to actually get the one currently used statically?

I don't think you can inject beans directly in a static class as it will be created before SpringBoot is instantiating beans. But you could set the bean in the static class using the @PostConstruct annotation.

@Autowired
public ApplicationContext applicationContext;

@PostConstruct
public void init() {
    HelperClass.setApplicationContext(applicationContext);
}

and

public class HelperClass {

    public static ApplicationContext applicationContext;

    public static void setApplicationContext(ApplicationContext applicationContext) {
        HelperClass.applicationContext = applicationContext;
    }

    public static Object staticMethod(String beanName) {
        return applicationContext.getBean(beanName);
    }
}
