Joi-with-Jest

This is a matchers that can be used with Jest testing framework to test any Json/Javascript schema with Joi

Install

$ npm install joi-with-jest

Usage

const matchers = require("joi-with-jest");
expect.extend(matchers);

and to validate your JSON or Javascript schema you can do

 
//Joi schema definition
 
let customer = Joi.object().keys({
    ascUser: Joi.object().keys({
        userName: Joi.string().email().required(),
        password: Joi.string().required(),
        firstName: Joi.string().max(40).required(),
        lastName: Joi.string().max(40).required(),
        cspKey: Joi.string(),
        cspUID: Joi.string(),
        status: Joi.string().valid("A", "B", "IA", "NF", "S").required(),
        orgID: Joi.string(),
        roles: Joi.array().items(
            Joi.object().keys({
                roleID: Joi.string().required(),
                status: Joi.string().valid("A", "B", "IA", "NF", "S").required()
            })
        ),
        audit: Joi.object().keys({
            createdOn: Joi.date().iso(),
            createdBy: Joi.string(),
            updatedBy: Joi.string(),
            updatedOn: Joi.date().iso()
        })
 
    }).required()
});
 
let options = { abortEarly: false, stripUnknown: false }
expect(object).toMatchSchema(customer, options);
 

And if any test fails, it will throw errors like

[{"message":"\"firstName\" is required","path":["ascUser","firstName"],"validationFailed":"required"}]
