HOW

expect performs strict primitive equality, boolean/nullish checks, and .not negation
toEqual and toStrictEqual perform deep structural equality assertions on objects and arrays
toMatchObject and toHaveProperty verify subset structures and nested object properties
toContain and toContainEqual assert collection containment and element equality
toBeGreaterThan, toBeLessThan, and toBeCloseTo validate numeric relationships and floating point values
toBeTypeOf and toBeInstanceOf evaluate type classifications and instance constructors
toSatisfy and toBeOneOf custom matchers evaluate predicate functions and element membership
toThrow verifies exception throwing and error type matching
Asymmetric matchers stringContaining, stringMatching, objectContaining, arrayContaining, any, anything, and closeTo match partial values
SchemaMatching and expect.schemaMatching validate data against Standard Schema V1 definitions
expect.extend registers custom matchers with custom pass and failure message logic
getState and setState inspect and update matcher execution context
