'Spring boot Test with non-Spring Boot Application

I have an application using Spring MVC 4, and not using any spring-boot-starter-* dependencies. i.e, I don't have that class with a main method calling SpringApplication.run. I'm configuring all by myself with xml and other @Configuration classes.

Question: Is it possible to configure Spring Boot Test (using the spring-boot-starter-test) in that non Spring Boot Application?

Solution 1:[1]

spring-boot-starter-test has dependency on spring-boot-test JAR. There are some spring-boot packages used. So if you wouldn't use these features, you may be able to use it as pure test dependency. But better alternative would be to use plain spring-test module. That covers most of the Spring test functionality anyway.

Solution 2:[2]

The testCompile('org.springframework.boot:spring-boot-starter-test') dependency has all you need, but it is dependency that you need to have, it will give you all power from spring-boot side, i.e. if you have your test class annotated with

@RunWith(SpringRunner.class)
@SpringBootTest(
    classes = ${YourMainClass}.class
)

it should work, even though I would strongly recommend using whole power of Spring Boot framework with the usage of all proper dependencies.

Test class:

@ContextConfiguration(locations = { "classpath:web-sdk-test-config.xml" })
@Test
@TestPropertySource("classpath:application.properties")
public abstract class AbstractTest extends AbstractTestNGSpringContextTests {
    private static final int TIMEOUT = 36000;


}
