Buck
much appreciated, and maybe TDD is off-topic ??? but better testing
seems good - it's the "full test suite" that has me stumped.
My main project now is feeding data to a robotic pick system.
Current phase is "partial production" meaning we feed selected
customer orders to the robot and if results are ok, we ship,
if not, we re-stock.
Maybe the key is "full test suite" means, for example, you do not
model the picking robot, you just cover basic module function to
ensure that all required output data is present and in the correct
format ?

RPGUnit from sourceforge.net I guess
I see they have a tutorial
maybe we can use here in the swamp
if you could expand some; much appreciated !
RPGUnit is loosely modelled after JUnit for Java. The main idea is to allow you to create a test suite that thoroughly tests your sub-procedures.
As far as this list is concerned, unfortunately there isn't any link between RPGUnit and RDp. In the Java world, JUnit is integrated with Eclipse and you can test while you develop. Very cool and very handy.
I'll risk my posting status by noting that JUnit and RPGUnit are implementations of a philosophy called TDD - Test Driven Development.
The main idea is to have complete test coverage of each function. Say you have a function that does XML character escaping. Your test suite will include a null string, a string of all blanks, a string of one character, etc.
How does this help us as programmers? Well, every time I start to work on a change, I run the full test suite first to verify that all tests pass. Then I write a new test to see if the new functionality is working. It had better fail because I haven't written the code yet.
This step proves that the test suite is behaving as expected. Now I write the code that implements the new functionality and run the test suite. It should pass all the tests. Now I am sure that my new functionality works AND that I haven't broken existing functionality.
Again, I apologise for the off-topic post.
