IIRC. you can just use <dtml-var testString newline_to_br>
to get the same result.
I know of no occurence where you have either \n or \r
but in the same string (and not just \n or \n\r)
But if you want to replace each, either:

<dtml-var expr="testString.replace('\r','\n')" newline_to_br>

or

<dtml-var
expr="testString.replace('\n','<br />').replace('\r','<br />')">

but beware the quoting.

Even better maybe you just use CSS for your layout:

<p style="white-space:pre">
<dtml-var testString>
</p>

or with ZPT:

<p style="white-space:pre" tal:content="options/testString">
Sampletext
</p>
