Hi John<br> great! so you covered all the cases!!.... it means you are a great programmer or mutation testing is not good :-) haha.<br> Seriously, it is great you could try it and thank you for the report.<br> We will check to see if we can do something to avoid changing the memory ceiling.<br>

see it the following week after my XtC talk in London. At the time I had promised to try it out.<br>

<br>
My Fractions Calculator has 105 Sunits to confirm the keyboard state machine works, the calculator grammar via Smacc is sane,<br>
and the math results are as defined by either Wolfram Alpha, or Microsoft Excel rules. Actually the number of tests are 210 because they are<br>
subclassed for Excel, but running just the Wolfram Alpha based ones were sufficient to test the code base.<br>
<br>
I had two problems, one where the RBParser choked on<br>
#(#foo:. #bar:.)<br>
Oops the code really should have been #(#foo: #bar:) or {#foo:. #bar:.}, still it shouldn't have given a walkback.<br>
<br>
The second was that I had to increase the memory ceiling of the macintosh squeak carbon VM from 512MB to 1.5GB via the info.plist<br>
so that a recursive error situation would not make the VM run out of memory before the Mutation testing runtime monitor would kill the<br>
runaway task.<br>
<br>
As a result over the 105 SUnits it reported:<br>
<br>
It made 874 mutants, 873 got killed, 1 was terminated.<br>
<br>
Which means I don't have any head scratching this afternoon.<br><font color="#888888">
