Added ability to specify feature file and line numbers from command line

[aharwood]

Hi,

I've made a small enhancement to RuntimeOptionsBuilder to allow the specification of which feature file (and optionally line numbers) to run. It seems that this functionality was present in the old addCliFilter(RuntimeOptions) method, but was lost when moving to the new method (I assume because it didn't fit with the style). I've tried to implement it in keeping with how you've done the tags. I've also updated the README to include a section on what can be specified from the command line.

I believe this would allow Issue #11 to be closed.

Example usage:

grails test-app :cucumber features/search.feature:10:20

Hi Adam,

The old addCliFilter was a bit dirty. Use of --options is tricky because grails eats them away. I tried using + instead but I did not like that.

I played around with your code and found a few things that could be improved.

• cucumber accepts also directories and not just .feature files
• prefixing of the files does not honor the featurePath configuration

I did not merge your code but it triggered implementation of the dir/file:line filter handling the cases above too.

thanks for working on this :-) !

I plan to release it next week as 0.8.0

Excellent, this functionality will be really handy. Looking forward to it!
