Regression testing - via a very short C testing framework

Code testing is important. Separation of code into separate, managable sections is important. Retesting of code running all the old tests is important when the code sections are enhanced / debugged.

At the end of this week's C course, we wrote a whole series of pieces of logic relating to web server log files - loading data into dynamic (realloc'd arrays of structs, and then extracting data from those structures. And we wrote an initial main routine to run and test from the command line. For initial development, that's great but ...
... the main couldn't remain as we started to build with the logic
... lots of sections / routine groups need testing.

Solution?
• Rename main to a different name such as test_access and leave it in the original file
• build a tiny test harness that runs each set of tests and correlates the results
• have the test harness send standard output (stdout) within the tests to a file

Result?
A rudemintary regression testing system, where each time you add a new set of routines or change something, you can rerun all the tests and get an automated set of replies.

The results of running the test suite look a bit boring:

  WomanWithCat:cj16 grahamellis$ ./framework
  
  .F..
  Failed 1 test(s) out of 4, passed 3
  
  WomanWithCat:cj16 grahamellis$


Commented framework source is [here] and tests and routines to be tested [here] and [here].

A little more about this newsletter ...

At Well House Consultants, we run niche IT training courses ... and we run a hotel for delegates on those courses and other visitors to Melksham too. And we make a lot of friends - have a lot of ambassadors with whom we want to keep in touch. So every day Graham (that's me, writing this piece) puts together an article or two which might include the latest sample programs that I've written during the current course, new information about Well House Manor - our business hotel, tips on search engine optimisation, announcements of upcoming public courses, pictures of local places, and even (on occasions) rants and whimsical pieces to keep those friends up to date and in touch. The feeds are available directlt via the Blog - "The Horse's Mouth", they're on our Twitter Feed and you can find me at my LinkedIn profile. But most people just want to look us up occasionally - every month or two, and then to catch up on the latest news just for their particular subjects of interest ... and that's what this newsletter is about

You'll find above the titles of ALL the new articles written in the last two months, listed by major subject area, and showing as (new) with their date of publication. You'll find additional articles in each category too - topping each category up to a minimum of five articles. And you'll find a link at the end of each section which lets you expand that section to show the titles of every article that's been published in that section. After all, "the old ones are often the best ones", aren't they?
