Load different application.yml in SpringBoot Test

Question

I\'m using a spring boot app which runs my src/main/resources/config/application.yml.

When I run my test case by :

@RunWith(SpringJUnit4ClassRunner.c

This might be considered one of the options. now if you wanted to load a yml file ( which did not get loaded by default on applying the above annotations) the trick is to use

@ContextConfiguration(classes= {...}, initializers={ConfigFileApplicationContextInitializer.class})

Here is a sample code

@RunWith(SpringRunner.class)
@ActiveProfiles("test")
@DirtiesContext
@ContextConfiguration(classes= {DataSourceTestConfig.class}, initializers = {ConfigFileApplicationContextInitializer.class})
public class CustomDateDeserializerTest {


    private ObjectMapper objMapper;

    @Before
    public void setUp() {
        objMapper = new ObjectMapper();

    }

    @Test
    public void test_dateDeserialization() {

    }
}

Again make sure that the setup config java file - here DataSourceTestConfig.java contains the following property values.

@Configuration
@ActiveProfiles("test")
@TestPropertySource(properties = { "spring.config.location=classpath:application-test.yml" })
public class DataSourceTestConfig implements EnvironmentAware {

    private Environment env;

    @Bean
    @Profile("test")
    public DataSource testDs() {
       HikariDataSource ds = new HikariDataSource();

        boolean isAutoCommitEnabled = env.getProperty("spring.datasource.hikari.auto-commit") != null ? Boolean.parseBoolean(env.getProperty("spring.datasource.hikari.auto-commit")):false;
        ds.setAutoCommit(isAutoCommitEnabled);
        // Connection test query is for legacy connections
        //ds.setConnectionInitSql(env.getProperty("spring.datasource.hikari.connection-test-query"));
        ds.setPoolName(env.getProperty("spring.datasource.hikari.pool-name"));
        ds.setDriverClassName(env.getProperty("spring.datasource.driver-class-name"));
        long timeout = env.getProperty("spring.datasource.hikari.idleTimeout") != null ? Long.parseLong(env.getProperty("spring.datasource.hikari.idleTimeout")): 40000;
        ds.setIdleTimeout(timeout);
        long maxLifeTime = env.getProperty("spring.datasource.hikari.maxLifetime") != null ? Long.parseLong(env.getProperty("spring.datasource.hikari.maxLifetime")): 1800000 ;
        ds.setMaxLifetime(maxLifeTime);
        ds.setJdbcUrl(env.getProperty("spring.datasource.url"));
        ds.setPoolName(env.getProperty("spring.datasource.hikari.pool-name"));
        ds.setUsername(env.getProperty("spring.datasource.username"));
        ds.setPassword(env.getProperty("spring.datasource.password"));
        int poolSize = env.getProperty("spring.datasource.hikari.maximum-pool-size") != null ? Integer.parseInt(env.getProperty("spring.datasource.hikari.maximum-pool-size")): 10;
        ds.setMaximumPoolSize(poolSize);

        return ds;
    }

    @Bean
    @Profile("test")
    public JdbcTemplate testJdbctemplate() {
        return new JdbcTemplate(testDs());
    }

    @Bean
    @Profile("test")
    public NamedParameterJdbcTemplate testNamedTemplate() {
        return new NamedParameterJdbcTemplate(testDs());
    }

    @Override
    public void setEnvironment(Environment environment) {
        // TODO Auto-generated method stub
        this.env = environment;
    }
}
