[lucaslacerdacl]

Version

29.7.0

Steps to reproduce

Jest dependencies:

"jest-environment-jsdom": "^29.7.0",
"@jest/types": "^29.6.3",
"@testing-library/jest-dom": "^6.4.2",
"@types/jest": "^29.5.12",
"jest": "^29.7.0",
"ts-jest": "^29.2.3",

Jest config:

import type {Config} from '@jest/types';

const baseConfig: Config.InitialOptions = {
  rootDir: '../../',
  preset: 'ts-jest',
  reporters: ['default'],
  clearMocks: true,
  testEnvironment: 'jest-environment-jsdom',
  transform: {
    '^.+\\.(ts|tsx)$': 'ts-jest',
  },
  moduleNameMapper: {
    'styled-components/macro': '<rootDir>/node_modules/styled-components',
  },
};

export default baseConfig;

hey @lucaslacerdacl I am not able to reproduce this
My test file is:

import { InputType } from '../enums/input-type';
import { getFormattedValue } from './input-mask';

describe('input-mask', () => {
  it('should mask phone number', () => {
    expect(getFormattedValue('1234567890', InputType.phone)).toBe(
      '(123) 456-7890',
    );
  });
  it('should mask zip code', () => {
    expect(getFormattedValue('1234567890', InputType.zip)).toBe('12345-6789');
  });
  it('should return the original value', () => {
    expect(getFormattedValue('1234567890', 'unknown' as any)).toBe(
      '1234567890',
    );
  });
  it('should return the original value if the value is empty', () => {
    expect(getFormattedValue('', InputType.phone)).toBe('');
  });
  it('should format complete Canadian postal code with hyphen', () => {
    expect(getFormattedValue('M5V3L9', InputType.zip)).toBe('M5V-3L9');
    expect(getFormattedValue('m5v3l9', InputType.zip)).toBe('M5V-3L9');
  });

  it('should format partial Canadian postal code without hyphen', () => {
    expect(getFormattedValue('M5V', InputType.zip)).toBe('M5V');
    expect(getFormattedValue('m5v', InputType.zip)).toBe('M5V');
  });

  it('should remove non-alphanumeric characters', () => {
    expect(getFormattedValue('M5V 3L9', InputType.zip)).toBe('M5V-3L9');
    expect(getFormattedValue('M5V-3L9', InputType.zip)).toBe('M5V-3L9');
    expect(getFormattedValue('M#5V@3L9', InputType.zip)).toBe('M5V-3L9');
  });
  it('should return just the first five digits when only those are provided', () => {
    expect(getFormattedValue('12345', InputType.zip)).toBe('12345');
    expect(getFormattedValue('12345-', InputType.zip)).toBe('12345');
  });
  it('should return just the last four digits when only those are provided', () => {
    expect(getFormattedValue('1234', InputType.phone)).toBe('1234');
  });
  it('should handle partial phone numbers', () => {
    expect(getFormattedValue('123', InputType.phone)).toBe('123');
    expect(getFormattedValue('1234567', InputType.phone)).toBe('(123) 456-7');
  });
});
