@eGavr , thank you for taking initiative and fixing.

Testing is necessary. Testing this project for now is a little bit odd, because the test suite has cases in it that don't pass, for yet to be fixed defects.

In order to ensure not to break existing functionality with a next release, please:

• Run test suite with your fix not in (previous commit), note what fails.
• Run test suite with your fix. Compare what fails then.

That protects quality and sanity.

To help prevent future regression, you could also add a test case in test.js that fails before your fix and then passes with your fix.

@srguiwiz

I've created a testing pull request #749 where I've just changed README and you can see in it that there are 7 broken tests.

In my PR there were 7 broken tests too.
Besides, I think that some tests are not stable and fail randomly.

Can you review my changes, please? It seems that they do not break the current functionality and fix the problem which I've described in the issue.
