I have some (non-Grails-artifact) classes that access the service layer beans via passing around the grailsApplication object. However I'm having trouble unit testing the classes implemented in this way. Why doesn't the bean get registered in the main context?
@TestMixin(GrailsUnitTestMixin)
class ExampleTests {
void setUp() {}
void tearDown() {}
void testSomething() {
defineBeans {
myService(MyService)
}
assert grailsApplication.mainContext.getBean("myService") != null
}
}
The above code fails with:
org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'myService' is defined
What I'm trying to do is access services from plain old Java classes via the grailsApplication. This works, but not in unit test environment. Should I do it differently?
class POJO {
MyService myService;
public POJO(GrailsApplication grailsApplication) {
myService = (MyService) grailsApplication.getMainContext().getBean("myService");
}
}
In my case (grails 2.4.4) the accepted solution didn't work but pointed me in the right direction, this line worked instead as the bean factory in the mainContext within my unit test was an OptimizedAutowireCapableBeanFactory
I have spent some time with the same issue, in my case running grails 2.2.4 and having (in src/groovy):
Which is a bit different to question author, but at least it will be useful for someone coming from search engine results
Nevertheless accepted answer did not work for me, so I came up with a bit different approach of mocking and registering service used in SomeClass.
The answer is that in the
GrailsUnitTestMixin
the applicationContext that holds your beans is set as theparentContext
in thegrailsApplication
So you can get your beans with:

Today I faced the same problem, and my solution is:
