SpringBootTest - Consider defining a bean of type 'java.lang.String' in your configuration

I am having trouble running my Spring boot tests, the ApplicationContext Failed to load, full error -

Description:

Parameter 0 of method createDatasourceBean in com.siemens.plm.it.configurator.DatasourceConfigurator required a bean of type 'java.lang.String' that could not be found.


Action:

Consider defining a bean of type 'java.lang.String' in your configuration.

The test class is in my src/test/java under the root project package - 

-com.someproject //SpringApplication.run
--com.someproject.test

And contains some basic MVC test, but the app fails before that in my contextLoad() - 

@RunWith(SpringRunner.class)
@SpringBootTest
public class SapConnectionApplicationTests {

    @Test
    public void contextLoads() {
    }

}

///EDIT

Running build without tests(-dSkipTest) works, and running the project works, it is only test classes fail.

DatasourceConfigurator class-

public abstract class DatasourceConfigurator {
    @Bean
   public TomcatEmbeddedServletContainerFactory embeddedServletContainerFactory() {
      return new 1(this);
   }

    protected ContextResource createContextResource(DatasourceProperties dbp) {
        ContextResource resource = new ContextResource();
        resource.setName(dbp.getJndiname());
        resource.setType(DataSource.class.getName());
        resource.setProperty("driverClassName", dbp.getDriverClassName());
        resource.setProperty("factory", dbp.getFactory());
        resource.setProperty("url", dbp.getUrl());
        resource.setProperty("username", dbp.getUsername());
        resource.setProperty("password", dbp.getPassword());
        resource.setProperty("initialSize", dbp.getInitialSize());
        resource.setProperty("maxActive", dbp.getMaxActive());
        resource.setProperty("minIdle", dbp.getMinIdle());
        resource.setProperty("maxIdle", dbp.getMaxIdle());
        return resource;
    }

    @Bean(destroyMethod = "")
    protected DataSource createDatasourceBean(String jndiName) throws IllegalArgumentException, NamingException {
        JndiObjectFactoryBean bean = new JndiObjectFactoryBean();
        bean.setJndiName(jndiName);
        bean.setProxyInterface(DataSource.class);
        bean.setLookupOnStartup(false);
        bean.setResourceRef(true);
        bean.afterPropertiesSet();
        return (DataSource) bean.getObject();
    }

    @Bean
    public PersistenceExceptionTranslationPostProcessor exceptionTranslation() {
        return new PersistenceExceptionTranslationPostProcessor();
    }

    protected abstract List<DatasourceProperties> getDatasourceProperties();
}

Try declaring a mocked DataSource bean in your test class:

@MockBean
DataSource dataSource;

Then just mock its methods using Mockito.when.

Spring is telling you that it's trying to create a bean using com.siemens.plm.it.configurator.DatasourceConfigurator.createDatasourceBean, and that that method requires a string, and it isn't sure where to get the string from. So either you need to provide a string that it can autowire, or you have to figure out why Spring is trying to invoke that method during context load.

You say this is only failing during the test run and not when the application is loaded, which ... suggests that somehow the jndi name is available to the application context auto wiring during application startup but not when the test is running. I don't have a great suggestion as to why that would be. If I were trying to debug at this point, I might put a breakpoint on createDatasourceBean and start the application in a debugger and figure out where Spring is getting the jndiName from and maybe that would tell me why it can't do the same thing when running the test.

Spring has a ton of ways in which it can resolve properties and components, which is uber-flexible, but that flexibility has a cost. It can be pretty hard to guess where something is coming from if you're not somewhat familiar with the application.
