In @SpringBootTest, is there a way to have SpringRunner.class and Theories.class co-exist?

Question

This is hopefully a simple question.

I have a Spring Boot Test.

The annotations are:

@RunWith(SpringRunner.class)
@SpringBootTest(classes = Main.class)
@TestPropertySource(locations { "myproperties.properties" })

I've got a test that I'd love to use @RunWith(Theories.class). The test is testing basically the same thing over several different places in my code.

Of course, @RunWith must be singular.

So is there a way to have the theories started up as a rule? Or SpringRunner.class? Or something so that they can co-exist?

Answer 1

There should be two ways to solve that:

1. SpringClassRule and SpringMethodRule <-- I use this approach

   just use

   @RunWith(Theories.class)
   public class YourTest {
       @ClassRule
       public static final SpringClassRule scr = new SpringClassRule();
   
       @Rule
       public final SpringMethodRule smr = new SpringMethodRule()
   

2. Initializing the TestContextManager Manually according to Baeldung it works for Parameterized, but I wouldn't know why it shouldn't work for Theories also ;) Generally, it is not recommended to initialize the TestContextManager manually. Instead, Spring recommends using SpringClassRule and SpringMethodRule.

   @RunWith(Parameterized.class)
   public class YourTest {
   
       private TestContextManager testContextManager;
       @Before
       public void setup() throws Exception {
           this.testContextManager = new TestContextManager(getClass());
           this.testContextManager.prepareTestInstance(this);
       }
