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.

“99 failing tests in the queue! 99 failing tests! Check one out, grind it out, 98 failing tests in the queue!”

So I'm facing this nearly twenty-hour long regression test and I had this idea—instead of querying the mocked end point if it did its thing or not, have the mocked endpoint check to see if it did its thing or not.

I now send the mocked endpoint the testcase itself (along with a query flag of true or false). The mocked endpoint will save this information, and set a queried flag for this testcase to false. If it is queried, it updates the queried flag for the given request. At the end of the regression test (and I pause for a few extra seconds to let any pending requests to hopefully finish), the mocked endpoint will then go through the list of all the testcases it was told about, and check to see if the query flag and queried flag match—if not, it logs an error.

Sure, now we have two error logs to check, but I think that's better than waiting nearly twenty hours for results.

I got a baseline time for the subset of the regression test without the mock checks—35 seconds. I'm trying to beat a time of 4 hours, 30 minutes with the mock checks.

The new method ran the subset in 40 seconds. The entirety of the regression test, 15,852 tests, took just a few minutes—about the same as before.

I can live with that.

Now all that's left is to write the validation logic—I still don't have it down yet.

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:, then add the date you are interested in, say 2000/08/01, so that would make the final URL:

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.
