在1983年的COBOL中见过:

   C   I don't know what this next bit does so I'll jump around it
       GOTO DONE.

This is a gathering place for all unit tests.
Create a TUnitTestWrapper, then call "RunAllUnitTests".

This class will create an instance of each thing to be tested, and call each of
their unit tests.

It does not really do any testing on it's own; it just gives a common place from
which to call everyone else's tests.

This way, one day, we can automate our testing with each build. [Cue laughter]

在一个著名的商业DOS电子表格应用程序中:

/* This comment was just added in order to check-in a file that was last 
checked in by [Insert Programmer FirstName] "Back-to-the-Future" [Insert 
Programmer LastName]. While testing for year 2000 problems, he accidentally 
checked-in this file while his machine clock was set forward to the year 2000. 
This meant that the source code was always newer than the object file and 
compiled every time the code was built. I'm checking this file in again to 
fix that. */
