How to load springboot custom test configuration for particular tests

I have two spring junit tests that require different configurations. These are as follows

package some.pkg.name;

@RunWith(SpringRunner.class)
@SpringBootTest
@ContextConfiguration(classes = {Test1.ContextConfig.class})
public class Test1 {

    @Test
    public void test1() {
        // do something
    }

    @Configuration
    @ComponentScan("some.pkg.name")
    public static class ContextConfig {
        // bean definitions here
    }
}


package some.pkg.name;

@RunWith(SpringRunner.class)
@SpringBootTest
@ContextConfiguration(classes = {Test2.ContextConfig.class})
public class Test2 {

    @Test
    public void test2() {
        // do something
    }

    @Configuration
    public static class ContextConfig {
        // bean definitions here
    }
}

When I run Test1 I end up with Test1's beans AND Test2's beans. I've been at it for a while but can't figure it out. What am I doing wrong? I've tried putting the config classes in their own package but it hasn't worked. In Test1 I need spring's component scan, in Test2 the beans are created "by hand". The default component scan for the project is some.pkg.

Any ideas?

If you need spring main application component scan beans then don't specify the custom configuration on that test class

@RunWith(SpringRunner.class)
@SpringBootTest
public class Test1 {

    @Test
    public void test1() {
       // do something
    }

}


@RunWith(SpringRunner.class)
@SpringBootTest
@ContextConfiguration(classes = {Test2.ContextConfig.class})
public class Test2 {

    @Test
    public void test2() {
       // do something
    }

    @Configuration
    public static class ContextConfig {
      // bean definitions here
    }
}

The problem was solved by putting the configuration classes outside of the component scan, like so:

package some.pkg.name;

import some.config.ContextConfigTest1;

@RunWith(SpringRunner.class)
@SpringBootTest
@ContextConfiguration(classes = ContextConfigTest1.class)
public class Test1 {

    @Test
    public void test1() {
        // do something
    }

}


package some.pkg.name;

import some.config.ContextConfigTest2;

@RunWith(SpringRunner.class)
@SpringBootTest
@ContextConfiguration(classes = ContextConfigTest2.class)
public class Test2 {

    @Test
    public void test2() {
        // do something
    }
}


package some.config;

@Configuration
public class ContextConfigTest2 {
    // bean definitions here
}

package some.config;

@Configuration
@ComponentScan("some.pkg.name")
public class ContextConfigTest1 {
    // bean definitions here
}
