Ah yes of course - I remembered that soon after I posted :)

Not sure on the exact question... all of the Java ones are checked exceptions. Scala doesn't force you to catch them, so I didn't. Realistically there should by a try block somewhere to handle Thrift and Cassandra errors.

A couple of things..

a) If you make it a trait - you can mix it in and just call tryNTimes without the object classifier - that's closer still, right?

b) You can still retry and function, by creating a curried function or function pointer and passing that in:

def myFunc(s:String) { println(s) }
def toRetry = myFunc("Hi!")
tryNTimes(toRetry, 5)

right? I used this style in some test code I just wrote, where I had a test sequence that applied to several code blocks, some that took params.

Nice - I like. Were all those exceptions run time exceptions - is that why you aren't catching them?

Excellent, that would be quite a bit nicer. Having the object/class pair is a bit clunky... Overall the framework is very nice though.

Hi Mark,

Thanks for your post.

2 tips for making your specification even more concise (with specs.1.6.0-SNAPSHOT or 1.5.1 SNAPSHOT):

This will make your specification class a JUnit test:
class BasicCassandra extends SpecificationWithJUnit { ... }

It is still runnable in the console with:

scala -cp <...> run BasicCassandra

And you can write (if you like it):

cass.connect().before
cass.close().after

Cheers,

Eric.

Wow! Just in time as I'm contemplating retrying slurping of a user's tweets. I'll add something like "requeue" as the final result where all N tries failed.
