Another problem is that you don't get a single indicator whether all the test cases passed. It's easy enough, with only three test cases, to scan the output looking for "FAIL however, when you have hundreds of test cases, it'll be more of a hassle. You don't want to spend your time slogging through test output checking answers when the computer can do it much more quickly and accurately. Consequently, each test case must be an expression that yields a boolean value-true or false, pass or fail. If you want to start with the simplest thing that could possibly work, you can just write a function that evaluates the test cases and AND s the results together. (defun test- (and ( ( 1 2) 3) ( ( 1 2 3) 6) ( ( -1 -3) -4) Whenever you want to run this set of test cases, you can. Since check is responsible for generating the code that ultimately runs the test cases, you just need to change it to generate code that also keeps track of the results. As a first step, you can make a small change to report-result so it returns the result of the test case it's reporting.
Create an edge by embracing a culture of experimentation, identifying the areas of greatest need and then leaning on employees with experience to teach others.
However, as you'll discover the first time a test case fails, the result reporting leaves something to be desired. When test- returns NIL, you'll know something failed, but you'll have no idea which test case it was. Since the second version is close to what you want in terms of functionality, your best bet is to see if you can factor out some of the annoying duplication. The simplest way to get rid of the repeated similar calls to FORMAT is to create a new function. What you'd really like is to be able to treat the expression as both code (to get the result) and data (to use as the label). Whenever you want to treat code as data, that's a sure sign you need a macro. A" ( ( 1 2 3) 6) ( 1 2 3) 6) (format t FAIL ;pass. a" ( ( -1 -3) -4) ( -1 -3) -4) Now each test case will be reported individually. If a particular test case fails, all you have to do is find the test case in the check form and figure out why it's failing. But if you write a lot of tests, you'll probably want to organize them somehow, rather than shoving them all into one function. ( ( 1 2) 3) pass. ( ( 1 2 3) 6) pass. ( ( -1 -3) -4) T And if you change one of the test cases so it fails,5 the final return value changes to NIL. Now running test- shows you exactly what's going on. CL-USER (test-) pass. ( ( 1 2) 3) pass. ( ( 1 2 3) 6) pass. ( ( -1 -3) -4) NIL This time the result reporting is more like what you want, but the code itself is pretty gross. Special Issue: Newborn Health in Uganda. Guest Editors: Kate Kerber 1, Stefan Peterson 2, 3, 4, 5 and Peter Waiswa 2,3,5. Published: 2015 CONTENTS. Articles. Copyright, Peter Seibel In this chapter you'll return to cutting code and develop a simple unit testing framework for Lisp. This will give you a chance to use some of the features you've learned about since Chapter 3, including macros and dynamic variables, in real code. Evelyn adjusted the sparkly center jewel on her plunging Sky top. The four of us-Evelyn and I, and Evelyns new boobs-were perched on a settee in Trish Putnams living room. The women of the Newbodies were arranged in a semicircle at our feet, sprawled on scattered stacks of fringed floor pillows. Strategic Planning.

If it is a more formal type, you should be direct in your opening paragraph and explain why you are writing. You should summarise the purpose and write in a clear manner so that the reader will be able to understand you. Once again, everyone knows what will be on that report when they leave. Nothing is hidden, and everything can be shown and explained. Are people allowed to accompany you during the entire inspection? What you'd really like is a way to write test functions as streamlined as the first test- that return a single T or NIL value but that also report on the results of individual test cases like the second version.
The main design goal of the test framework will be to make it as easy as possible to add new tests, to run various suites of tests, and to track down test failures.
