Re: Introduction: Basics of Software-Based Test Systems

NO RATINGS
Just saying -- we have several options, generally, when doing test. You typically have a device-under-test, which can be a chip, a module, a plug-in, a card, a sub-assembly, a major assembly, a complete system. Sometimes the DUT plugs into a test bench somehow (an exerciser which only faintly resembles the end-use environment), because of a need for more switches etc to test more options than the native environment would access. Sometimes the DUT is complicated enough that a valid test environment HAS to essentially duplicate the native (end-use) environment, in which case the "testing" tends to include presenting the widest possible range of valid external inputs to confirm receipt and handling...

Wow -- not a simple subject -- I'll be interested to see how you break this down into functional concepts to tackle it in bite-sized pieces.

 

Just a note: click-and-drag and CTRL-C to save what you type if you get longwinded, because the system DOES sometimes glitch-and-barf and discard your stuff. If so, click and CTRL-V to paste that "thank gods I saved a backup copy" chunk of text, and try again.
