Test Assertion

Definitions

1. A statement within a test that declares an expected condition — such as assertEquals(actual, expected) or expect(result).toBe(true) — which either passes silently or fails the test with a diagnostic message when the condition does not hold.

   In plain English: A check inside a test that says 'this value should equal that value' and fails the test if it does not.

   Example: "The test has 15 assertions but only the last one checks the return value — the rest validate intermediate state, which makes failures hard to diagnose."
