Thank you for the great work of this series, kindly correct the link in the description to this https://github.com/sebastianbergmann/phpunit/blob/9f2ebaf18f7741a5ee587f80a42632edaa42d424/src/Framework/TestCase.php#L4

A final note - unlike interfaces, a child class cannot inherit from more than one abstract class.

Since abstract classes is quite an advanced topic, you are strongly advised to [read up the official documentation on php.net],
look up a few examples of production-level software using abstract classes to get an insight as to when and how they are used, and experiment with abstract classes in your local server to further understand their behaviour before undertaking this Kata.

Enable Coq version 8.15

Permit Coq Version 8.15

Coq 8.15 should be permitted.

In the kata description where it says:

I spent some time and a lot of coffee :'(

Lua translation!

Groovy: arguments to assertEquals are reversed. It should be assertEquals(expected, actual).

Java: the countChar test assertion message is very unhelpful (expected: <true> but was: <false>)

Nim translation moved from duplicate kata Alternate case.

What's wrong with the Groovy translation? Why is it not merged? Same thing for the Java translation
