HOW

createExpect configures Chai with JestChaiExpect, JestAsymmetricMatchers, and JestExtend
toBe and toEqual perform primitive value and deep equality assertions
toMatchObject and toHaveProperty verify subset structures and nested object properties
toContain and toContainEqual assert element presence 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, and ArrayContaining match partial values
expect.extend registers custom matchers with custom pass and failure message logic
getState and setState inspect and update matcher execution context
