Configuration for loading story from String? - jbehave

Question

I have a web service posting Gherkins stories to a back-end and would like to load those stories into configuration as a string without having to save them as a file.
Can this be accomplished?

Answer 1

You need to implement your custoom story loader that will collect stories from the web service and pass them to JBehave.
You need also use a GherkinStoryParser to translate stories from Gherking format to JBehave format.
An example configuration might look like in the following example.
A custom story loader that retrieves stories from a map of strings:
public class MyStoryLoader implements StoryLoader {
private Map<String,String> stories;
public MyStoryLoader( Map<String,String> storiesToLoad){
this.stories = storiesToLoad;
}
public String loadStoryAsText(String storyName) {
return stories.get( storyName );
}
}
Some class that collects stories from the web service and return them as a map with unique story names and story bodies:
public class StoryCollectorFromWebService {
private final static String storyTemplate = "Feature: A story that is saved in the string\n"
+ "\n"
+ "Scenario: Read the scenario from the string\n"
+ "\n"
+ "Given There is some story named ${name} saved in the string\n"
+ "When I run this story named ${name}\n"
+ "Then I can see it's results";
// This is a method that collects stories from the Web Service and saves them in a map of strings
public Map<String,String> getStoriesFromWebService(){
Map<String,String> storiesFromWebService = new HashMap<String,String>();
String storyNames[] = {"A","B","C","ABC","Some story", "Another story"};
for(String storyName: storyNames)
storiesFromWebService.put( storyName, storyTemplate.replace("${name}", storyName));
return storiesFromWebService;
}
}
and sample configuration to run these stories using our StoryLoader and GherkinStoryParser:
public class RunAs_JUnitStories extends JUnitStories {
public RunAs_JUnitStories() {
configuredEmbedder().embedderControls().doGenerateViewAfterStories(true).doIgnoreFailureInStories(true)
.doIgnoreFailureInView(true).useThreads(1).useStoryTimeoutInSecs(60);
}
Map<String,String> storiesFromWebService = new StoryCollectorFromWebService().getStoriesFromWebService();
#Override
protected List<String> storyPaths() {
return new ArrayList<String>( storiesFromWebService.keySet());
}
#Override
public Configuration configuration() {
Class<? extends Embeddable> embeddableClass = this.getClass();
ParameterConverters parameterConverters = new ParameterConverters();
ExamplesTableFactory examplesTableFactory = new ExamplesTableFactory(new LocalizedKeywords(), new LoadFromClasspath(embeddableClass), parameterConverters);
parameterConverters.addConverters(new DateConverter(new SimpleDateFormat("yyyy-MM-dd")),
new ExamplesTableConverter(examplesTableFactory));
return new MostUsefulConfiguration()
// Use custom story loader
.useStoryLoader(new MyStoryLoader( storiesFromWebService ))
// Use Gherkin parser
.useStoryParser( new GherkinStoryParser() )
.useStoryReporterBuilder(new StoryReporterBuilder()
.withCodeLocation(CodeLocations.codeLocationFromClass(embeddableClass))
.withDefaultFormats()
.withMultiThreading(true)
.withFormats(CONSOLE, TXT, HTML, XML))
.useParameterConverters(parameterConverters);
}
#Override
public InjectableStepsFactory stepsFactory() {
return new InstanceStepsFactory(configuration(), new MySteps());
}
}
Here is a link to a working example: https://github.com/kordirko/TestJBB
You can try import it into Eclipse and play with it, but I apologize if something goes wrong,
It's my first project on github, I'am still learning how to do it :)
