Mock Randomizer
===============
fills a structure with randomized data to mock a service or other model provider. number of items in a collection of objects can also be random.
Installation
npm install @joxnathan/mock-randomizer
Usage
import mock from '@joxnathan/mock-randomizer';
this.history.GetChangeHistory = () => Promise.resolve(
mock.filledList({
Id: 'guid',
TimeStamp: 'date:now:now',
User: { Id: 'number:100:501', Name: 'string:8', Email: 'email' },
Data: [{
Id: 'number:1000:2001',
ChangeType: 'choose:Insert,Update,Delete',
TableName: 'choose:Claimant,Processor,Advisor,Supervisor,Client,Vendor',
RecordId: 'number:10:41',
FieldName: 'choose:Id,Name,Address,City,State,Zip',
PrevValue: '{}',
CurrValue: '{}'
}]
}, { min: 11, max: 75 }, { Data: { max: 4 } }).map(entry => {
const getData = () => JSON.stringify(mock.filledObject({

}, { Locations: { min: 1, max: 3 } }));
for (const data of entry.Data || []) {
const vals = {
prev: ['Delete', 'Update'].includes(data.ChangeType) ? getData() : undefined,

console.log({ hist });
Potential Upcoming Features
1. DSL 'email:[props]' - add option to specify that the value relies on another.
2. DSL 'string:2 number:1:4 number:1:10 number boolean' - string the dsl commands together in a single property. (not really too sure about this one)
Contributing
In lieu of a formal style guide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code.
