Why bean are not injected in test class

I have a jar which will be included in spring boot application, I am trying to do an integration test in this, the project has the configuration class for creating the data source and JDBC template, I am using testing,

There is no application class in this project when this jar included in another project that project fetches data perfectly fine but not in same project

spring-boot-starter-test is added as a dependency

Configuration

@Configuration
    public class DatabaseAccesManagementConfig {

        @Bean(name = "accessmngmtDataSource")
        @Qualifier("accessmngmtDataSource")
        @ConfigurationProperties(prefix = "accessmngmt.datasource")
        public DataSource accessmngmtDataSource() {
            return DataSourceBuilder.create().build();
        }

        @Bean(name = "accessmngmtJdbcTemplate")
        @Qualifier("accessmngmtJdbcTemplate")
        public JdbcTemplate accessmngmtJdbcTemplate(@Qualifier("accessmngmtDataSource") DataSource accessmngmtDataSource) {
            return new JdbcTemplate(accessmngmtDataSource);
        }
    }

Dao class

 @Repository
    public class ResourcePrivilegesDao {
        static final  Logger log = LoggerFactory.getLogger(ResourcePrivilegesDao.class);
        @Autowired
        @Qualifier("accessmngmtJdbcTemplate")
        private JdbcTemplate jdbcTemplate;

        public List<RP> getAll() {
            log.debug("entering getAll()");
            String sql = "SELECT * FROM rp";
            RowMapper<RP> rowMapper = new RPRowMapper();
            List<RP> result = this.jdbcTemplate.query(sql, rowMapper);
            return result;
        }
    }

Test class

@SpringBootTest
@TestPropertySource(locations="classpath:application-test.properties")
@ContextConfiguration(classes = DatabaseAccesManagementConfig.class)
public class ResourcePrivilegesDaoTest {

    @Autowired
    DatabaseAccesManagementConfig databaseAccesManagement;

    @Autowired
    ResourcePrivilegesDao dao;

    @Test
    public void testGetAll() {
        System.out.println(databaseAccesManagement);
        List<ResourcePrivileges> list = dao.getAll();
        Assert.notNull(list, "No resource privileges found");
        Assert.notEmpty(list);
    }

}

test property inside 

environment=test

#Access management db details
accessmngmt.database.url=//xxyyy/am
accessmngmt.database.username=user
accessmngmt.database.password=password

In the test class, you missed the @RunWith(SpringRunner.class) which configure a unit test that need Spring's DI.

Take a look for the doc spring unit test

In order for the unit test to run a batch job, the framework must load the job's ApplicationContext. Two annotations are used to trigger this:

@RunWith(SpringJUnit4ClassRunner.class): Indicates that the class should use Spring's JUnit facilities

@ContextConfiguration(locations = {...}): Indicates which XML files contain the ApplicationContext.

Notice that, the SpringRunner is an alias for the SpringJUnit4ClassRunner. So we can use @RunWith(SpringRunner.class) instead of @RunWith(SpringJUnit4ClassRunner.class) with a shorter name.

Updated:

For the datasource properties injection, The @EnableConfigurationProperties annotation should annotated on the Test class.

Also, you use accessmngmt.datasource in DatabaseAccesManagementConfig class, while the prefix is not matched accessmngmt.database in application-test.properties. Here you must unify them, so you can inject the properties into the bean.
