Custom Story Reporters in Jbehave

I am following the below posts for creating a Custom Reporter in my JBehave.

Whenever I try to create a class, I am getting the below error.

WebStories.MyStoryReporter is not abstract and does not override abstract method pendingMethods(java.util.List<java.lang.String>) in org.jbehave.core.reporters.StoryReporter

So now I have made the class as abstract as shown below

public class MyStoryReporter implements org.jbehave.core.reporters.StoryReporter

Now the real problem is I cannot call the MyStoryReporter from .withReporters since its an abstract class

.useStoryReporterBuilder(new StoryReporterBuilder()
                    .withCodeLocation(codeLocationFromClass(embeddableClass))
                    .withDefaultFormats()
                    .withFormats(ANSI_CONSOLE, HTML, XML, STATS)
                    .withFailureTrace(true)
                    .withReporters(new MyStoryReporter));

I think I am missing some basic things. Can anyone help me in this context.

Solution

You need to refresh some basics about java interfaces, abstract clasess and inheritation.
Study these links: http://docs.oracle.com/javase/tutorial/java/concepts/interface.html
http://docs.oracle.com/javase/tutorial/java/IandI/
https://docs.oracle.com/javase/tutorial/java/IandI/abstract.html

org.jbehave.core.reporters.StoryReporter is an interfce that defines 21 abstract methods: http://jbehave.org/reference/stable/javadoc/core/org/jbehave/core/reporters/StoryReporter.html
If you want to implement this interface in some class, you need to provide an implementation for all of these 21 methods in implementing class.

If you don't want to define all methods, but only one (or a few of them), then extend NullStoryReporter class instead of implementing StoryReporter interface. NullStoryReporter provides null (empty) implementation for all StoryReporter methods: http://jbehave.org/reference/latest/javadoc/core/org/jbehave/core/reporters/NullStoryReporter.html

For example, if you want to use only one method successful in your custom reporter, just do:

public class MyStoryReporter extends org.jbehave.core.reporters.NullStoryReporter{
  @Override
     public void successful(String step) {
        log.info(">>successStep:" + step);
     }
}
