expect(x).isGoing.toEqual(y); passes if x and y eventually become equivalent

expect(x).isNotGoing.toEqual(y); passes if x and y do not eventually become equivalent

BOOL

expect(x).toBeYes(); passes if x is a BOOL value of YES

expect(x).toBeNo(); passes if x is a BOOL value of NO

Class

expect(x).toConformToProtocol(y); passes if class or object x conforms to protocol y

Object

expect(x).toConformToProtocol(y); passes if class or object x conforms to protocol y

expect(x).toRespondToSelector(y); passes if class or object x responds to selector y

Number

expect(x).toBeLessThan(y); passes if x is less than y

expect(x).toBeLessThanOrEqualTo(y); passes if x is less than or equal to y

expect(x).toBeGreaterThan(y); passes if x is greater than y

expect(x).toBeGreaterThanOrEqualTo(y); passes if x is greater than or equal to y

expect(x).toBeCloseTo(y, z); passes if x is equal to y to a precision of z decimal places

expect(x).toBeInTheRangeOf(y, z); passes if x is in the range of [y, z]

Exceptions

expect(^{ expr; }).toThrow(e); passes if expr throws an exception e when executed

expect(^{ expr; }).toChange(x.hello, z); passes if expr changes x.hello by amount z

String

expect(x).toMatch(y); compares x to a regex pattern y and passes if they match

Collection

expect(x).toBeEmpty(); passes if x is empty

expect(x).toHaveCountOf(y); passes if x contains y number of objects
