HOW

expect performs strict primitive equality and .not inversion
toEqual and toStrictEqual perform deep object and array structural equality assertions
toMatchObject and toHaveProperty verify subset structures and nested object properties
toContain and toContainEqual assert element presence and membership in arrays and strings
toBeGreaterThan, toBeLessThan, and toBeCloseTo validate numeric relationships and floating point values
toBeTypeOf and toSatisfy evaluate type classifications and custom predicate functions
toThrow verifies exception throwing and error type matching
Asymmetric matchers stringContaining, stringMatching, objectContaining, arrayContaining, any, and anything match partial values
expect.extend registers custom matchers with custom pass and failure message logic
getState and setState inspect and update matcher execution context
