The content of this blog is my personal opinion only. Although I am an employee - currently of Nvidia, in the past of other companies such as Iagination Technologies, MIPS, Intellectual Ventures, Intel, AMD, Motorola, and Gould - I reveal this only so that the reader may account for any possible bias I may have towards my employer's products. The statements I make here in no way represent my employer's position, nor am I authorized to speak on behalf of my employer. In fact, this posting may not even represent my personal opinion, since occasionally I play devil's advocate.

Positive confirmation of success

Test suites should not just say "all tests passed".  Or, even worse, return success silently.

They should at least optionally list what tests have been run.  Or at least a summary of how many tests have been run.

It has happened before that tests have been omitted by accident.  Test suites themselves can have bugs.

This is just an example of where positive conformation of an action can be important.

However, it is nice to be able to turn off that positive confirmation, e.g. in UNIX pipelines.

Myself, I like "folding"such confirmation.
