raisch / chai-joi Goto Github PK

It would be nice to have error message when it was expected to validate but didn't validate.

For example,
I have a validation that I expect to pass, but doesn't

It shows me

AssertionError: { Object (error, value) } should validate but does not

Could you bump the version of this project, now that the joi compatibility issue has been resolved?

I just downloaded the npm package and it has merge conflicts and an older version of lodash. I cannot use it. Fix it asap.

Current release is broken. download from NPM, it contains a merge conflict

Use joi: 13.1.1 or newer.

Example:

const chai = require('chai');
const joi = require('joi');

chai.should();
chai.use(require('chai-joi'));

describe('.should.validate', function() {
  it('should validate', function() {
    let schema = joi.object().keys({
      'foo': joi.any().required(),
      'bar': joi.number().required()
    });
    let data = {'foo': 'bar', 'bar': 5};
    let result = joi.validate(data, schema);

    console.log(result);

    result.should.validate;
  });
});

Output:

$ mocha -- test/api-validation-test.js


  .should.validate
{ error: null,
  value: { foo: 'bar', bar: 5 },
  then: [Function: then],
  catch: [Function: catch] }
    1) should validate

  1) .should.validate
       should validate:

Hello,

is this project still maintained, or is abandoned?

Thank you

Hi,

I'm trying to understand how this package is intended to be used.

I use Joi to validate API calls, whether these be restful endpoints or simply functions.

When testing my API, I will use Joi.attempt() or Joi.assert() to ensure the API doesn't accept undesired input.

What would be very helpful would be a helper for testing the exceptions. For example,

function foo(bar) {
  Joi.assert(bar, Joi.string().required().min(4).label('bar').description('four-letter word'));
}

describe('foo()', () => {
  it('should throw if not passed a four-letter word', () => {
    // too basic
    expect(() => foo('baz')).to.throw(Error);

    // too coupled to Joi's API
    expect(() => foo('baz')).to.throw('"bar" length must be at least 4 characters long');

    // desired syntax, or something like it
    expect(() => foo('baz')).to.throw(Error).with.type('string.min').and.path('bar');
  });
});

Perhaps this is already possible without this addon.
