Spring test + DBUnit Unable to load DataSet

Question

I am trying to write an integration test within my Spring Boot application. I have problems getting the setup configuration right. The following Exception is thrown:

java.lang.IllegalArgumentException: Unable to load dataset from "sampleData.xml" using class com.github.springtestdbunit.dataset.FlatXmlDataSetLoader

Things I've already tried:

1. Changing the name of the sampleData.xml file.
2. Using value="" notation.
3. Using classpath: before the file name.
4. Using an additional "/" before the file name.

The sampleData.xml is in the same directory as my test class. I guess i am missing something stupid.

sampleData.xml:

<?xml version="1.0" encoding="UTF-8"?>
<dataset>
<Benutzer userId="1" firstName="peter" lastName="pan" email="peter@bla.de"/>
<Benutzer userId="2" firstName="hans" lastName="wurst" email="e@e.de"/>
</dataset>

            .andExpect(model().attribute("Benutzer", hasSize(2)))
            .andExpect(model().attribute("Benutzer", hasItem(
                    allOf(
                            hasProperty("userId", is(1l)),
                            hasProperty("firstName", is("peter")),
                            hasProperty("lastName", is("pan")),
                            hasProperty("email", is("peter@bla.de"))
                    )
            )))
            .andExpect(model().attribute("Benutzer", hasItem(
                    allOf(
                            hasProperty("userid", is(2l)),
                            hasProperty("firstName", is("Hans")),
                            hasProperty("lastName", is("Wurst")),
                            hasProperty("email", is("e@e.de"))
                    )
            )));
    }
}

ExampleApplicationContext:

@Configuration
@PropertySource("classpath:application.properties")
public class ExampleApplicationContext {
@Resource
private Environment environment;

@Bean
public DataSource dataSource(){

    JdbcDataSource dataSource = new JdbcDataSource();
    dataSource.setURL(environment.getProperty("spring.datasource.url"));
    dataSource.setUser(environment.getProperty("spring.datasource.username"));
    dataSource.setPassword(environment.getProperty("spring.datasource.password"));
    return dataSource;
    }
}

When using Maven you have 2 directories under src/test one for java files and one for anything else resources . If you put anything other as .java files in src/test/java those won't be processed and copied to the target/test-classes directory and as such will not be available at the time the tests are run.

You need to put the .xml files in the src/test/resources directory to have them processed and copied.
