function assertEquals

Re-export

import { assertEquals } from "https://deno.land/std@0.222.0/assert/mod.ts";

assertEquals<T>(

actual: T,

expected: T,

msg?: string,

options?: { formatter?: (value: unknown) => string; },

)

Make an assertion that actual and expected are equal, deeply. If not deeply equal, then throw.

Type parameter can be specified to ensure values under comparison have the same type.

Examples

Example 1

import { assertEquals } from "https://deno.land/std@0.222.0/assert/assert_equals.ts";

assertEquals("world", "world"); // Doesn't throw
assertEquals("hello", "world"); // Throws

Note: formatter option is experimental and may be removed in the future.

Type Parameters
