Regex issues

[catalintgv]

I`m using this regex: \d+(?:Mi|Gi|M|G)\b\Z and also as alternative \d+(?:Mi|Gi|M|G)\b(?!\s) but unittest does not recognize \Z and ?!

Hello @catalintgv,

It is correct the unittest does not support \Z and ?! regex.
See the following site for the supported regex syntax https://pkg.go.dev/regexp/syntax.

I also will add the reference to the documention.
