I'm looking forward to the following test case errors being resolved.

 FAILlib/rules/max-empty-lines/__tests__/index.js
●max-empty-lines › reject › [1] › "<div>\n<style>\n/* horse */\n\n\n</style>\n</div>" › no description
expect(received).toEqual(expected)
    Expected value to equal:
[]
    Received:
[{"column": 1, "line": 5, "rule": "max-empty-lines", "severity": "error", "text": "Expected no more than 1 empty line (max-empty-lines)"}]
    Difference:
- Expected
+ Received
- Array []
+ Array [
+   Object {
+     "column": 1
+     "line": 5
+     "rule": "max-empty-lines"
+     "severity": "error"
+     "text": "Expected no more than 1 empty line (max-empty-lines)"
+   }
+ ]
 128 |                    })
 129 |.then(({ output warnings })=> {
> 130 |                      expect(output.results[0].warnings).toEqual(warnings);
     |^
 131 |                      expect(output.results[0].parseErrors).toEqual([]);
 132 |                    });
 133 |                });

@EliazTray hi! Would you like to look into this PR again?

Hi! I got this.
Would you review this again?
thanks.

Looks good! But 5 of 7 testRule() are missing fix: true, without it Jest won't check autofixing.

I'm sorry for missing some test.

[hudochenkov]

Great! Thank you!
