 every project will have a set of tests available. The testing framework that is
 currently available is found [here](https://github.com/remzi-arpacidusseau/ostep-projects/tree/master/tester).
 A specific testing script, found in each project directory, can be used to run

+For example, in the initial utilities project, the relatively simple `wcat`
+program that you create can be tested by running the `test-wcat.sh` script.
+This could be accomplished by the following commands:
+```sh
+prompt> git clone https://github.com/remzi-arpacidusseau/ostep-projects
+prompt> cd ostep-projects/initial-utilities/wcat
+prompt> emacs -nw wcat.c 
+prompt> gcc -o wcat wcat.c -Wall 
+prompt> ./test-wcat.sh
+test 1: passed
+test 2: passed

+test 4: passed
+test 5: passed
+test 6: passed
+test 7: passed

+Of course, this sequence assumes (a) you use `emacs` (you should!), (b) your
+code is written in one shot (impressive!), and (c) that it works perfectly
+(well done!). Even for simple assignments, it is likely that the
+compile/run/debug cycle might take a few iterations.
