# The Boston Diaries

The ongoing saga of a programmer who doesn't live in Boston, nor does he even like Boston, but yet named his weblog/journal “The Boston Diaries.”

Go figure.

### The upper bound on the number of test cases in the new regression test is 2,359,296, but it'll probably, hopefully, be less than that.

We're coming up with a new regression test at work that kind of, maybe, combines both the original “Project: Wolowizard” and the new “Project: Sippy Cup” and my manager, S, came up with 11 variables to test; A with values A1, A2 ‥ A8; B with values B1, B2, B3, B4; C with values etc. And multiplying out all the possible values of all the variables, I end up with a potential 2,359,296 possible test cases.

Now, some of the cases aren't possible. For instance, values D1, D2, D4and D6 can only be tested with value H1 (or rather, with those values of D, H1 is the only value H can have), while D3, D5, D7 and D8 can only be tested with values H2, H3 and H4. So, just looking at D and H, it's … um … let's see … there are two parties involved, both with D and H values, and does it make sense for P1D5 to call P2D5? Um … well, in this case, H doesn't really apply to P1 so out of a possible 32 combinations, only … um … 24 really apply.

I think.

Yeah, it's going to be real fun trying to puzzle out all the cases.

## Obligatory Miscellaneous

You have my permission to link freely to any entry here. Go ahead, I won't bite. I promise.

The dates are the permanent links to that day's entries (or entry, if there is only one entry). The titles are the permanent links to that entry only. The format for the links are simple: Start with the base link for this site: https://boston.conman.org/, then add the date you are interested in, say 2000/08/01, so that would make the final URL:

https://boston.conman.org/2000/08/01

You can also specify the entire month by leaving off the day portion. You can even select an arbitrary portion of time.

You may also note subtle shading of the links and that's intentional: the “closer” the link is (relative to the page) the “brighter” it appears. It's an experiment in using color shading to denote the distance a link is from here. If you don't notice it, don't worry; it's not all that important.

It is assumed that every brand name, slogan, corporate name, symbol, design element, et cetera mentioned in these pages is a protected and/or trademarked entity, the sole property of its owner(s), and acknowledgement of this status is implied.
