Select features and scenarios using tags

[erikedin]

One should be able to select which features/scenarios to execute based on the associated tags.

Look up the exact syntax Cucumber uses for selecting scenarios on the command line.

[erikedin]

Cucumber uses a and/or expression, with optional parentheses, like

(@tag1 or @tag2) and (not @tag3)

Pythons Behave uses tags in a slightly different format.

--tags=@one,@ortheother
--tags=-@notthisone
--tags=@this --tags=@andthis

I'm leaning towards Cucumber, simply as it's the most standard. For an initial implementation however, we could restrict ourselves to a single tag.

Did we spot such tags in grakn feature or step files?

[erikedin]

I haven't looked carefully, but I know they at least use the @ignore tag in some places, presumably to skip certain scenarios. So, at minimum, we need to support saying not @ignore when running features.

I see 👍
