!3 System Under Test

'''Currently only available in Java'''

!-Using SystemUnderTest allows you to let SliM directly invoke a method on your SystemUnderTest without having to create a method in a SliM fixture for it.-!

!4 Example
{{{
import fitnesse.slim.SystemUnderTest;

/**
 * The slim fixture.
 */
public class SlimDriver {
  
  // field MUST be declared PUBLIC
  @SystemUnderTest
  public Service service = new Service();

  public void init() {
    Database.clean();
  }

}

/**
 * The service under test.
 */
public class Service {

  public void createPerson(String name) {
    Database.persist(new Person("name"));
  }

  public boolean exists(String name) {
    return Database.get(name) != null;
  }
 
}

}}}

With the !-@SystemUnderTest-! annotation you can now say:

!|script|SlimDriver|
|init|
|create person|Ben Vonk|
|ensure|exists|Ben Vonk|

When a method that should be invoked on the !-SliM-! fixture is missing, it will try to invoke that method on a '''public''' field annotated with !-SystemUnderTest-!.
