What is definition assertation?

Assertion is a statement that is made with confidence and declared as a fact. It is a form of expression that is intended to convey a belief or opinion, and is often used to persuade or convince others of a particular point of view. In programming, assertion refers to a piece of code that is used to verify the correctness of an assumption or condition. It is used to detect and report errors and bugs in code by testing assumptions that are supposed to be true. Assertions are commonly used in software testing and debugging to ensure that the code is functioning as expected. An assertion can be either true or false and it is used to verify that a certain condition is met during the execution of a program.
