The ActiveProfilesResolver interface allows you to programmatically determine which Spring profiles are active during a test.
Definition of ActiveProfilesResolverVersion: 7.0.3 package org.springframework.test.context;
@FunctionalInterface
public interface ActiveProfilesResolver {
String[] resolve(Class<?> testClass); 1
}
We need to register our custom resolver implementation with the resolver attribute of the @ActiveProfiles annotation. The following example demonstrates this process.
Example
Creating a simple Spring application
package com.logicbig.example;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Profile;
@Configuration
public class AppConfig {
@Bean
@Profile("windows")
public MyService myServiceA() {
return new MyServiceA();
}
@Bean
@Profile("other")
public MyService myServiceB() {
return new MyServiceB();
}
}
package com.logicbig.example;
public interface MyService {
public String doSomething();
}
package com.logicbig.example;
public class MyServiceA implements MyService {
@Override
public String doSomething() {
return "in " + this.getClass().getSimpleName();
}
}
package com.logicbig.example;
public class MyServiceB implements MyService {
@Override
public String doSomething() {
return "in " + this.getClass().getSimpleName();
}
}
Implementing MyActiveProfilesResolver
package com.logicbig.example;
import org.springframework.test.context.ActiveProfilesResolver;
public class MyActiveProfilesResolver implements ActiveProfilesResolver{
@Override
public String[] resolve(Class<?> testClass) {
String os = System.getProperty("os.name");
String profile = (os.toLowerCase().startsWith("windows")) ? "windows" : "other";
return new String[]{profile};
}
}
The JUnit test
Following test will fail if run other than Windows O.S.
package com.logicbig.example;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.ExtendWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ActiveProfiles;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit.jupiter.SpringExtension;
import static org.junit.jupiter.api.Assertions.assertEquals;
@ExtendWith(SpringExtension.class)
@ContextConfiguration(classes = AppConfig.class)
@ActiveProfiles(resolver = MyActiveProfilesResolver.class)
public class MyServiceTests {
@Autowired
private MyService dataService;
@Test
public void testDoSomething() {
String s = dataService.doSomething();
System.out.println(s);
assertEquals("in MyServiceA", s);
}
}
Output$ mvn test -Dtest=MyServiceTests
