@deposits/validators/src/swift-code/swiftCode.spec.js

A collection of Fintech-specific and general-purpose validators, designed to extend popular validation libraries like Vuelidate, Zod, and yup.

import { swiftCode } from "./index";
import { expect, test, describe } from "@jest/globals";

describe("swiftCode", () => {
  // Valid SWIFT codes
  test("returns true for a valid SWIFT code with 8 characters", () => {
    expect(swiftCode("ABCDEF12")).toBe(true);
    expect(swiftCode("12345678")).toBe(true);
  });

  test("returns true for a valid SWIFT code with 11 characters", () => {
    expect(swiftCode("ABCDEF12GHI")).toBe(true);
    expect(swiftCode("12345678ABC")).toBe(true);
  });

  // Invalid SWIFT codes
  test("returns false for a SWIFT code with less than 8 characters", () => {
    expect(swiftCode("ABCDEF1")).toBe(false);
    expect(swiftCode("1234567")).toBe(false);
  });

  test("returns false for a SWIFT code with more than 11 characters", () => {
    expect(swiftCode("ABCDEF12GHIJ")).toBe(false);
    expect(swiftCode("12345678ABCD")).toBe(false);
  });

  test("returns false for a SWIFT code with non-alphanumeric characters", () => {
    expect(swiftCode("ABCDEF12!@#")).toBe(false);
    expect(swiftCode("12345678-AB")).toBe(false);
  });

  test("returns true and trims SWIFT code", () => {
    expect(swiftCode(" ABCDEF12")).toBe(true);
    expect(swiftCode("12345678 ")).toBe(true);
  });

  test("returns false for a SWIFT code with whitespace", () => {
    expect(swiftCode(" ABCD EF12")).toBe(false);
    expect(swiftCode("1234 5678 ")).toBe(false);
