OutOfMemoryErrors in EditDistance.calculateMatrix() #375

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
I have a spec that has a class produce several kB of text and compares that to 
an expected result. When the spec succeeds, everything goes well, but if the 
texts differ, I get an OutOfMemoryError, even with 8 GB of heap space. Maybe, 
to prevent this from happening, there should be a string length threshold above 
which the distance is no longer calculated?
Actually I don't care about the distance anyway, I just want to see the 
differences in the report. Can I tweak the error reporter to not calculate the 
distance?

Thanks for the report. What exactly do you mean by "I just want to see the 
differences in the report"? To work around the problem, use `equals()` rather 
than `==`.

A side-by-side comparison or a unified diff output would be great, but I guess, 
the regular equality comparison report should do it too.

Thanks a lot!

Maybe you could add support for using a custom renderer - maybe via an 
annotation or a Groovy Category? Something like

use(MyCustomFailedComparisonRenderer){
  actual == expected
}
