Run each Scenario as a TestNG @Test.

[corinned]

Summary

Currently, cucumber-testng provides the ability to execute each cucumber feature file as one TestNG Test. This fix allows you to run each Scenario as a Test.

Details

AbstractTestNGCucumberTests.class contains a Test method with groups="cucumber-scenarios". The DataProvider for this Test pulls all Scenarios and Scenario Outlines in order to execute each one as its own TestNG test.

A sample implementation of cucumber-scenarios is:

TestNG testNG = new TestNG();
testNG.setGroups("cucumber-scenarios");
testNG.setTestClasses(new Class[]{new AbstractTestNGCucumberTests() {}.getClass()});
testNG.run();

Motivation and Context

#1113

How Has This Been Tested?

Tests added to the existing cucumber.api.testng tests. Additional testing done from a separate java project utilizing the updated library.

@corinned I appreciate your effort very much. But ... The reason I don't think this PR should be merged is that it is built on outdated code, that is cucumber.runtime.model.*. With the upgrade of Cucumber-JVM from Gherkin v2.12.2 (see #1035) all of cucumber.runtime.model.* will be removed its functionality replaced by the Gherkin compiler which produces pickles, which are the bases of execution.

The upgrade of Cucumber-JVM from Gherkin v2.12.2 is already long overdue, considering the Cucumber-Ruby was upgraded to a new version of Gherkin in Cucumber-Ruby v2.1.0 - which was release September 11, 2015.

If you would like to implement the feature of this PR on top of #1035, I would be happy to review and work with you on that.

Thanks, @brasmusson, I will take a look at #1035.

This will be really useful if we can just run each scenario as a separate Test. Can we do this with current version?

[brasmusson]

@corinned Now that the master branch has been updated to use Gherkin v4, the current implementation of this PR is obsolete, however a re-implementation on the updated master is highly appreciated. Hint: Use Runtime.compileFeature to get the scenarios/pickles to be executed, and execute them like the Android executor does.
