覆盖application.properties以在Spring-boot应用程序中进行集成测试

Question

I have a standard spring-boot app and I want to use MS SQL database for the production environment, whereas for integration tests I'd like to use h2 databse. The problem is that I wasn't able to find out, how to override the default application.properties file. Even though I was trying to follow some tutorials, I didn't come up with the right solution...maybe I'm just missing something...

The main class:

@SpringBootApplication
@EnableTransactionManagement
public class MyApplication {
    public static void main(String[] args) {
        SpringApplication.run(MyApplication .class, args);
    }
}

and the class with tests:

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = MyApplication.class)
@WebIntegrationTest
public class MessageControllerTest {

    @Autowired
    MessageRepository messageRepository;
    ...
    ...
    ...
    @Test
    public void testSomething(){
    ...
    ...
    ...
    ...
    }
}

So the question is, how to force the spring-boot to use application-test.properties file when running the tests, instead of application.properties , which should be used during the run time.

I tried for example to replace @WebIntegrationTest annotation with @TestPropertySource(locations="classpath:application-test.properties") , but this results in java.lang.IllegalStateException: Failed to load ApplicationContext .

Answer 1

Assuming you have a application-test.properties file in your app.

I do it in two ways :

1.CLI JVM Args

mvn spring-boot:run -Drun.jvmArguments="-Dspring.profiles.active=test

2. add the application-test.properties as an active profile.

add the spring.profiles.active=test in the application.properties and it will load your application-test.properties file.

3. As you pointed to in your answer annotate a class test with a specific active profile ( which is not suitable when having a large test classes i think ) @ActiveProfiles("test")

Answer 2

Actually it was pretty easy...after several hours of trying, I've realized that I just needed to annotate my test class with @ActiveProfiles("test") annotation.

    @ActiveProfiles("test")
    @RunWith(SpringJUnit4ClassRunner.class)
    @SpringApplicationConfiguration(classes = MyApplication.class)
    @WebIntegrationTest
    public class MessageControllerTest {

        @Autowired
        MessageRepository messageRepository;
        ...
        ...
        ...
        @Test
        public void testSomething(){
        ...
        ...
        ...
        ...
        }
    }
