nice article...

Here’s my current definition of a testable system:

“For each logical part of the system, a unit test can be written relatively easily and quickly that satisfies all the following PC-COF rules at the same time:

Partial runs are possible
Consistent results on every test run
Configuration is unneeded before run
Order of tests does not matter
Fast run time”
