I have configuration file:

@Configuration
public class UrlAnalyzerConfiguration {

    @Bean
    @Qualifier("usersDatabase")
    public File getUsersDatabaseFile() {
        return Paths.get("src/main/resources/database/users.csv").toFile();
    }

    @Bean
    @Qualifier("urlsDatabase")
    public File getUrlsDatabaseFile() {
        return Paths.get("src/main/resources/database/urls.csv").toFile();
    }
}

And configuration for tests:

@TestConfiguration
public class TestConfig {

    @Bean
    @Qualifier("usersDatabase")
    public File getUsersDatabaseTestFile() {
        return Paths.get("src/test/resources/database/users.csv").toFile();
    }

    @Bean
    @Qualifier("urlsDatabase")
    public File getUrlsDatabaseTestFile() {
        return Paths.get("src/test/resources/database/urls.csv").toFile();
    }
}

My repository uses one of that beans:

    private final File usersDatabase;
    
    @Autowired
    public UserRepositoryImpl(@Qualifier("usersDatabase") File usersDatabase) {
        this.usersDatabase = usersDatabase;
    }

My repostitory tests file:

@SpringBootTest
@Import(TestConfig.class)
public class UserRepositoryTest {
    @Autowired
    private UserRepository userRepository;
    
    // tests here
}

At the result my main program works properly, but tests fail with followi message in the end:

Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type 'java.io.File' available: expected single matching bean but found 2: getUsersDatabaseTestFile,getUsersDatabaseFile

I have found the problem:

@TestConfiguration class is used in addition to your application’s primary configuration. It means, that tests use @Configuration and @TestConfiguration together! But anyway, how can I use then my beans properly ?

CodePudding user response：

You can use a combination of @Profile and @ActiveProfiles to load only the desired classes for your tests. See prototype below.

Configuration

@Configuration
@Profile("test")
public class TestOnlyConfigs {
    // define beans
}

Test

@ActiveProfiles("test")
public class Tests {
    // write tests
}
