Hi there, I think the tests have been fixed in master. Can you please merge to check that they pass?

Thanks

@johnwiseheart
I rebased off master, all tests are passing now.

@johnwiseheart Anything else I can do for this?

[johnwiseheart]

Sorry I missed this earlier: can you add your rule to this list: https://github.com/palantir/tslint/blob/master/src/configs/all.ts

[michaelblack]

It is added there, though it's the most permissive case allowing all comment types to be present.
