How do I put TestConfiguration in an abstract class?

Question

I have some Spring tests that all define the same test configuration:

    @TestConfiguration
    public static class TestConfig {
        @Bean
        public EmployeeClient employeeClient(MockMvc mockMvc) {
            return new EmployeeClient(mockMvc);
        }
    }

To reduce replication I put that code into an abstract class and had each test extend that abstract class. However, this threw Spring unresolved dependencies - it couldn't resolve EmployeeClient.

How can I make this work?

One of the ways is to make your Test class use multiple configuration files.

@Configuration
class CommonBeans {
}

@Configuration
class SpecificBeans {
}

@ContextConfiguration(classes = {CommonBeans.class, SpecificBeans.class}) 
public class MyAppTest {
  ------
}

In your test package if you are creating a configuration using @TestConfiguration instead of @Configuration then you have to use @Import annotation to make use of that.

@TestConfiguration
public class TestBeans {
    
}

@Import(TestBeans.class)
public class MyAppTest {
      ------
}
