The structure for SUnits has been in Squeak for a while, but only forty (40) out of 44,000 methods actually have a validating test.    I have embarked on a radical program to improve that.  Here is how I have changed things:
> [ ] To test a method, you needs to make up a receiver, arguments, and a known answer.  Scott Wallace is introducing an 'Instance Browser' to Squeak that shows you an example receiver and arguments for each method.  It lets you run the example.  But, where are we going to get the example receivers and arguments for a method shown in an Instance Browser?  They can be the same as for a test of the method.  I have written code that generates objects that can be used for *either* an SUnit test, or an example method call.
> [ ] Another thing that should be associated with each method is some 'type information'.  This is the protocol that each argument object needs to respond to.  The same mechanism that produces a test case can store this info also.
> [ ] In classic SUnits, there is a separate 'testing class' for each class in Squeak.  This would double the number of classes, and is too much overhead.  I have created a new subclass of TestCase that owns a Verifier.  Verifier is a subclass MessageSend that holds the answer that the method is supposed to produce.

>             Verifier #('desiredAnswer' 'passed')
>                  VerifierOfProperty #('theTest')
> I have made a subclass of TestCase that holds a Verifier.  A TestSuite of these behaves like a normal test suite, and does not do too much violence to the careful design of SUnits.
> [ ] A Verifier can only test (a) whether a method returns the correct value and (b) whether it gets an error while running.  A VerifierOfProperty tests for a specific state change after a method has run.  Classic SUnits allow other kinds of assertions and tests.  Except for verifying that a method produces a certain kind of error in a certain case, a series of VerifierOfProperty can test everything that a classic TestCase can.
> [ ] To collect the test cases, I simply enumerate the implementors of #exampleFor:, and call each one with 'all'.  That returns a list of Verifiers, which are run as test cases.
> [ ] The SUnit code comes with a TestRunner user interface.  Say

> and click on Run All.  After you have my update, the TestCase  called TestViaMethodCall collects and runs all tests that are created with #exampleFor:.  (One drawback is that when a method has more than one test, the individual subtests are not named.  We could give them names in the future.)

> Experimental!  Puts up mild border feedback when a pluggable-list-morph has the keyboard focus.  The color used is the same as the text-highlight color; this establishes a modicum of consistency: when a *text* pane of a window has the keyboard focus, the feedback is the text-highlighting in that same text-highlight color.  This is an experimental add-on to Dan's lazyKeyboardFocus experiment, attempting to work around the problem that whenever the keyboard focus lazily remained in a list pane after the mouse left the pane, there was no user feedback designating which list pane would receive keystrokes -- sometimes a serious problem because the same command-key can mean radically different things depending on which pane gets the command."

> That's not all.  If you type in a menu, it builds a pattern string, which appears at the bottom of the menu.  Whenever the pattern is not empty, only items that match are presented.  If only one item matches the pattern (or in any menu with only one item), the option is given to confirm with CR or cancel with ESC.
