示例1: diff

// Generate a string that will highlight the difference between two values
// with green and red. (similar to how github does code diffing)
function diff(a: any, b: any, options?: JestDiffOptions): string | null {
  if (Object.is(a, b)) {
    return NO_DIFF_MESSAGE;
  }

  const aType = getType(a);
  let expectedType = aType;
  let omitDifference = false;
  if (aType === 'object' && typeof a.asymmetricMatch === 'function') {
    if (a.$$typeof !== Symbol.for('jest.asymmetricMatcher')) {
      // Do not know expected type of user-defined asymmetric matcher.
      return null;
    }
    if (typeof a.getExpectedType !== 'function') {
      // For example, expect.anything() matches either null or undefined
      return null;
    }
    expectedType = a.getExpectedType();
    // Primitive types boolean and number omit difference below.
    // For example, omit difference for expect.stringMatching(regexp)
    omitDifference = expectedType === 'string';
  }

  if (expectedType !== getType(b)) {
    return (
      '  Comparing two different types of values.' +
      ` Expected ${chalk.green(expectedType)} but ` +
      `received ${chalk.red(getType(b))}.`
    );
  }

  if (omitDifference) {
    return null;
  }

  switch (aType) {
    case 'string':
      return diffStrings(a, b, options);
    case 'boolean':
    case 'number':
      return comparePrimitive(a, b, options);
    case 'map':
      return compareObjects(sortMap(a), sortMap(b), options);
    case 'set':
      return compareObjects(sortSet(a), sortSet(b), options);
    default:
      return compareObjects(a, b, options);
  }

示例2: getValues

export const errorMessage = (
  option: string,
  received: any,
  defaultValue: any,
  options: ValidationOptions,
  path?: Array<string>,
): void => {
  const conditions = getValues(defaultValue);
  const validTypes: Array<string> = Array.from(
    new Set(conditions.map(getType)),
  );

  const message = `  Option ${chalk.bold(
    `"${path && path.length > 0 ? path.join('.') + '.' : ''}${option}"`,
  )} must be of type:
    ${validTypes.map(e => chalk.bold.green(e)).join(' or ')}
  but instead received:
    ${chalk.bold.red(getType(received))}

  Example:
${formatExamples(option, conditions)}`;

  const comment = options.comment;
  const name = (options.title && options.title.error) || ERROR;

  throw new ValidationError(name, message, comment);
