Spring profiles and testing

Looking at Biju's answer I found a working solution.

I created an extra context-file test-context.xml:

<context:property-placeholder location="classpath:config/spring-test.properties"/>

Containing the profile:

spring.profiles.active=localtest

And loading the test with:

@RunWith(SpringJUnit4ClassRunner.class)
@TestExecutionListeners({
    TestPreperationExecutionListener.class
    })
@Transactional
@ActiveProfiles(profiles = "localtest")
@ContextConfiguration(locations = {
    "classpath:config/test-context.xml" })
public class TestContext {

  @Test
  public void testContext(){

  }
}

This saves some work when creating multiple test-cases.

The best approach here is to remove @ActiveProfiles annotation and do the following:

@RunWith(SpringJUnit4ClassRunner.class)
@TestExecutionListeners({
    TestPreperationExecutionListener.class
    })
@Transactional
@ContextConfiguration(locations = {
    "classpath:config/test-context.xml" })
public class TestContext {

  @BeforeClass
  public static void setSystemProperty() {
        Properties properties = System.getProperties();
        properties.setProperty("spring.profiles.active", "localtest");
  }

  @AfterClass
  public static void unsetSystemProperty() {
        System.clearProperty("spring.profiles.active");
  }

  @Test
  public void testContext(){

  }
}

And your test-context.xml should have the following:

<context:property-placeholder 
  location="classpath:META-INF/spring/config_${spring.profiles.active}.properties"/>

public class LoginTest extends BaseTest {
    @Test
    public void exampleTest( ){ 
        // Test
    }
}

Inherits from a base test class (this example is testng rather than jUnit, but the ActiveProfiles is the same):

@ContextConfiguration(locations = { "classpath:spring-test-config.xml" })
@ActiveProfiles(resolver = MyActiveProfileResolver.class)
public class BaseTest extends AbstractTestNGSpringContextTests { }

MyActiveProfileResolver can contain any logic required to determine which profile to use:

public class MyActiveProfileResolver implements ActiveProfilesResolver {
    @Override
    public String[] resolve(Class<?> aClass) {
        // This can contain any custom logic to determine which profiles to use
        return new String[] { "exampleProfile" };
    }
}

This sets the profile which is then used to resolve dependencies required by the test.

Can I recommend doing it this way, define your test like this:

@RunWith(SpringJUnit4ClassRunner.class)
@TestExecutionListeners({
    TestPreperationExecutionListener.class
    })
@Transactional
@ActiveProfiles(profiles = "localtest")
@ContextConfiguration
public class TestContext {

  @Test
  public void testContext(){

  }

  @Configuration
  @PropertySource("classpath:/myprops.properties")
  @ImportResource({"classpath:context.xml" })
  public static class MyContextConfiguration{

  }
}

with the following content in myprops.properties file:

spring.profiles.active=localtest

With this your second properties file should get resolved:

META-INF/spring/config_${spring.profiles.active}.properties
