Assertokcondition

Assertokcondition is a programming construct used to verify that a given domain-specific condition holds at a certain point in execution. It is intended to express that the system, or a component within it, is in an overall OK state, rather than merely being true in a narrow, low-level sense. In practice, assertokcondition is often implemented as a runtime check that triggers error handling when the predicate is false.

The primary purpose of assertokcondition is to enforce invariants, preconditions, or postconditions that are meaningful to the business logic or system health. By naming the check in terms of an OK state, the construct communicates intent more clearly than a generic assertion. Implementations vary: some environments throw exceptions or terminate the program, while others return error codes or log a failure for later analysis. In unit tests, assertokcondition can be used to document expected healthy states and to fail fast when those states are not met.

Typical usage involves passing a boolean predicate that represents an OK condition, along with an optional message describing the failure. Example: assertokcondition(user.isActive && account.balance >= 0, "User state not OK: inactive or negative balance").

Notes and considerations include performance impact, configurability (enabling or disabling in production), and how it compares to standard assertions or contract programming. It is often beneficial in large codebases to provide consistent, domain-relevant failure reporting through assertokcondition. See also: assertion, contract programming, precondition, postcondition.
