Functions

equal

zena
function equal<T>(actual: T, expected: T, message: String = 'Values not equal', loc: String | null = __LOCATION__): void

equalText

zena
function equalText(actual: String, expected: String, loc: String | null = __LOCATION__): void

Like equal for strings, with a failure message that shows both values (JSON-escaped) — the generic equal cannot render a T.

notEqual

zena
function notEqual<T>(actual: T, expected: T, message: String = 'Values should not be equal', loc: String | null = __LOCATION__): void

same

zena
function same<T>(actual: T, expected: T, message: String = 'References not identical', loc: String | null = __LOCATION__): void

notSame

zena
function notSame<T>(actual: T, expected: T, message: String = 'References should not be identical', loc: String | null = __LOCATION__): void

isNull

zena
function isNull<T extends anyref>(value: T | null, message: String = 'Expected null', loc: String | null = __LOCATION__): void

isNotNull

zena
function isNotNull<T extends anyref>(value: T | null, message: String = 'Expected non-null value', loc: String | null = __LOCATION__): void

isTrue

zena
function isTrue(value: boolean, message: String = 'Expected true', loc: String | null = __LOCATION__): void

isFalse

zena
function isFalse(value: boolean, message: String = 'Expected false', loc: String | null = __LOCATION__): void

less

zena
function less(actual: i32, expected: i32, message: String = 'Expected actual < expected', loc: String | null = __LOCATION__): void

lessOrEqual

zena
function lessOrEqual(actual: i32, expected: i32, message: String = 'Expected actual <= expected', loc: String | null = __LOCATION__): void

throws

zena
function throws(fn: () => void, message: String = 'Expected function to throw', loc: String | null = __LOCATION__): void
