Why here: assertEquals(3,Solution.solve("())(((")); the correct answer is 3, and not 1? There are 4 "(" and 2 ")", so I just need to reverse one "(". What I'm missing here?

NaN expected:true but was:false

Okay. If you right-click that line of text and click "inspect element" it'll show you in the dev tools what that text should be. That'll help for now until they fix the bug.

Now I get:
infinitTest(PluralTest)
✘ NaN expected: but was:

Interesting. I believe there may have been a bug where the <true> and <false> became HTML tags accidentally; but it looks okay for me at the moment. I just tried your code and got: expected:<true> but was:<false>.

I've added messages to the tests all the same. Could you retry and let me know what you get?

Same problem.

Which language? And could you give me your code between code tags, please?

```
code here
```

This test fails for me:
infinitTest(PluralTest)
✘ expected: but was:

any clue?

Isn't a pretty expensive solution?

I got: ✘ expected:<14> but was:<17>

I run my code in my IDE and the result was ok (14). Anyone has an idea what's going on?
