How can I validate fake data generated by Faker?

How can I validate fake data generated by Faker?

You can validate fake data by using libraries like Joi or Yup to define schemas and check the generated data against them.

Can you show me an example of using Joi for validation?

Sure! Here's a simple example:

const Joi = require('joi');

const schema = Joi.object({
  name: Joi.string().min(3).required(),
  email: Joi.string().email().required(),
});

const fakeData = {
  name: 'John Doe',
  email: '[email protected]',
};

const { error } = schema.validate(fakeData);
if (error) {
  console.log('Validation error:', error.details);
} else {
  console.log('Validation successful!');
}

What if the data doesn't match the schema?

If the data doesn't match the schema, Joi will return an error object that contains details about what failed validation.
