Hapi Lab how to test all the required fields - hapi.js

Question

Is there a way to check all the required fields
without the need of a test each field.
validation rules
const Confirmation = Joi.any().valid(Joi.ref('password')).required().options({ language: { any: { allowOnly: 'must match password' } } });
const Email = Joi.string().email();
const Firstname = Joi.string().regex(/^[a-zA-Z\']+$/).min(2).max(30);
const Lastname = Joi.string().regex(/^[a-zA-Z\']+$/).min(2).max(30);
const Password = Joi.string().min(3).max(30);
const Username = Joi.string().regex(/^[a-zA-Z\-\.]+$/).min(3).max(30);
exports.create = {
payload: {
email: Email.required(),
firstname: Firstname.required(),
lastname: Lastname.required(),
password: Password.required(),
password_confirmation: Confirmation,
username: Username.required()
}
};
test
'use strict';
const Lab = require('lab');
const lab = exports.lab = Lab.script();
const Code = require('code');
const Server = require('../../index');
lab.experiment('User', function() {
lab.test('create firstname should be required', function (done) {
const options = {
method: 'POST',
url: '/api/users',
payload: {
email: 'me#mydomain.com',
password: 'mysecret'
}
};
Server.inject(options, function(response) {
const result = response.result;
Code.expect(response.statusCode).to.equal(422);
Code.expect(result.message).to.equal('child "firstname" fails because ["firstname" is required]');
done();
});
});
//AND SO ON
lab.test('create firstname should be required', function (done) {
const options = {
method: 'POST',
url: '/api/users',
payload: {
email: 'me#mydomain.com',
password: 'mysecret',
firstname: 'me'
}
};
Server.inject(options, function(response) {
const result = response.result;
Code.expect(response.statusCode).to.equal(422);
Code.expect(result.message).to.equal('child "lastname" fails because ["lastname" is required]');
done();
});
});
});

The answer from #simon-p-r would be a possible solution. But I do not understand why you want to validate the Joi Schemas by checking each required field with a test in the first place. As far as I can tell Joi has a test-coverage of 100% and can be considered thoroughly tested - so why do that again?
I would just test the success and failure case as well as some edge cases (like confirmation of password missing, wrong, etc.)...
'use strict';
const Lab = require('lab');
const lab = exports.lab = Lab.script();
const Code = require('code');
const Server = require('../../index');
lab.experiment('User', function() {
//Failure case
lab.test('create should fail if required fields are missing', function(done) {
const options = {
method: 'POST',
url: '/api/users',
payload: {
email: 'me#mydomain.com',
firstname: 'foo',
lastname: 'bar'
}
};
Server.inject(options, function(response) {
Code.expect(response.statusCode).to.equal(400);
done();
});
});
//Success case
lab.test('create should succeed if all fields are valid', function(done) {
const options = {
method: 'POST',
url: '/api/users',
payload: {
email: 'me#mydomain.com',
firstname: 'foo',
lastname: 'bar',
password: 'secret',
password_confirmation: 'secret',
username: 'foo.bar'
}
};
Server.inject(options, function(response) {
Code.expect(response.statusCode).to.equal(200);
//maybe do some more checks on the response here...
done();
});
});
//Edge cases
lab.test('create should succeed if all fields are valid', function(done) {
const options = {
method: 'POST',
url: '/api/users',
payload: {
email: 'me#mydomain.com',
firstname: 'foo',
lastname: 'bar',
password: 'secret',
password_confirmation: 'something_else',
username: 'foo.bar'
}
};
Server.inject(options, function(response) {
Code.expect(response.statusCode).to.equal(400);
//maybe do some more checks on the response here...
done();
});
});
//And so on...
});
I hope this helps.

If you want to test all the field's validation you may want to set abortEarly to false in the options of validate method. If you are using built-in validation via route config set options object like so
{
method: 'POST',
path: '/api/users',
config: {
handler: handlerFunc,
validate: {
payload: Joi.schema(),
options: {
abortEarly: false
}
}
}
},
This should catch all errors.
