assertion

Firmly stated claim

An assertion is a confident, forceful statement—a claim presented as fact: Her assertion that the project would fail proved correct.

The word implies the speaker expects to be believed, whether or not evidence supports the claim.

In programming, an assertion is a statement that checks whether a condition is true, halting execution if it fails.
