Test

A test is a structured procedure designed to evaluate whether a subject, claim, or system meets specified criteria. The Concise Oxford English Dictionary defines a test as: "a procedure intended to establish the quality, performance, or reliability of something".

Tests can serve multiple purposes. For example, tests can be used to determine what someone knows, or can do, for example through multiple choice questions in an exam, or written assignments. Medical tests assess whether or how parts of the body are functioning via medical procedures, such as blood tests that determine the presence or absence of substances. In product testing, tests are used to establish whether products function as intended. 

 Types of tests 
In science, researchers perform tests to identify, quantify, or characterize substances. They also perform statistical hypothesis tests to examine of predictions are corroborated or falsified. In product testing a product’s performance, safety, quality, and compliance is examined to help ensure that what consumers buy is reliable, and safe. Assessment testing refers to the systematic gathering of information—through standardized tests, measurements, and evaluation procedures—to understand individual differences in abilities, traits, behaviors, or psychological characteristics. In psychological and educational contexts, assessments are designed to be standardized, reliable, and valid, ensuring that results provide meaningful information for decision‑making. These tests may measure cognitive skills, social traits, motives, adjustment, or other aspects of human functioning. Personality tests, a specialized subset of psychological assessments, measure personal characteristics known as traits, which are thought to explain variability in behavior and experience. Personality assessment seeks to define and quantify traits in an objective way so they can be compared across individuals or groups.
