spring - Prevent Application / CommandLineRunner classes from executing during JUnit testing

Question

If in your TestCase class there is this annotations:

@SpringApplicationConfiguration(classes = {Application.class})

this will cause the Application.class, implementing the CommandLineRunner interface, to run the required method

public void run(String... args) throws Exception

I still think this is, mostly, a not wanted behaviour, since in your test environment you may not want to launch the entire application.

I have in mind two solution to circumvent this problem:

1. to remove the CommandLineRunner interface from my Application class
2. to have a different context for testing

Both this solution requires lot of coding. Do you have a more convenient solution?

Answer 1

Jan's solution can be achieved easier.

In your test class, activate the "test" profile:

@RunWith(SpringJUnit4ClassRunner.class)
@ActiveProfiles("test")
public class MyFancyTest {}

In your CommandLineRunner set the profile to NOT test:

@Component
@Profile("!test")
public class JobCommandLineRunner implements CommandLineRunner {}

Then you don't have to manually set the profile in the Application.
