What does testiness mean?
Testiness is a noun meaning irritability, touchiness, or a readiness to become annoyed and take offence. It is commonly used to characterize a person's mood or general disposition: one might describe a colleague's testiness as the result of fatigue, or identify it as a recurring obstacle to cooperation. The word often carries a mildly critical or disapproving tone, suggesting that the behaviour is unnecessary, uncomfortable for others, or both. It can also be used more neutrally when discussing an interpersonal problem, as in an analysis of a negotiator's testiness during a difficult discussion. Although testiness may refer to a single outburst, it often implies a habitual tendency to react impatiently or defensively. In everyday language, testy is considerably more common, but the noun is useful when one needs to name irritability as a quality, characteristic, or recurring pattern of behaviour.

Where does testiness come from?
Testiness is an English formation created by adding the productive suffix -ness to the adjective testy. The base testy comes from test and developed in the sense of being irritable or inclined to take offence; testiness applies the suffix to name that quality. Its formation is transparent rather than a borrowing as a whole, while related forms such as tester and testable also trace back to the same verbal root.
How testiness is actually used
Testiness is relatively informal and often mildly disapproving. It can describe a temporary mood or a person's habitual temperament, although the adjective testy is much more common in everyday use.
