HOW

expect(received).toBe(expected) asserts strict primitive equality and reference identity
expect(received).toEqual(expected) asserts deep equality over nested objects and arrays
expect(fn).toThrow(expected) captures errors and asserts exception messages or error instances
expect.extend(customMatchers) registers custom assertion matchers returning pass status and message functions
expect(promise).resolves and expect(promise).rejects unwrap async promises for chained assertions
expect.assertions(count) verifies that the exact number of assertions were executed during a test
expect.soft(received) performs assertions without immediately halting test execution upon failure
