How to add parameters to JUnit tests? Is it possible to add them like in testNg?

Question

I would like to know, if it is possible to add parameters to Junit tests like you do it in testNg with the xml-Files. I know that you can have parameterized tests in Junit, but that's not what I want.

A short example how I do it now:

String example = "test"
String name = "test
...
@Test
public void testCase(){
    Page.addParameter(example);

And I want to get rid of these variables in the method, and want to get it from a xml-File or an other method.

Does anybody have an idea how to solve that?

If you use Spring you can annotate JUnit test with @ContextConfiguration passing some context.xml configuration, where you can also specify String properties.

For this you have to add dependency on String Test (org.springframework:spring-test) and use it similar to this example (in Groovy):

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = ['/config/dao-context.xml'])
class ClientServiceImplTest {
    ...
}

UPDATE:

You can add following bean to your context.xml, to load properties from some .properties file

// context.xml
<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
  <property name="ignoreUnresolvablePlaceholders" value="true"/>
  <property name="location" value="file:test\resources\config\server.properties"/>
</bean>

<context:component-scan base-package="your.package" />


// Java code using property - autowired value by Spring
@Value("${server.dataPassword}")
private String dataPassword;

// server.properties
server.dataPassword=pwd

How to get the values out of the xml-File or communicate with them?

@Buzz: I updated my answer to show how to load properties with Spring and use them in Java code

Obviously I'm doing something wrong. If I want to access the variables like you mentioned it, I always get null as value for the variable.

@Buzz: this is probably because you don't set component-scan for autowiring. I updated context.xml to show how it could be done (I use Spring 4). In any case you can easily find documentation by googling "spring value annotation"
