Jest and ValidationRules tests

Help Requests
1

Hello,

I’m trying to learn how Jest work and I’m trying to cover our ValidationRules we have set up in our SPA which runs with webpack and javascript.

We have a DOM filled with numbers from 0-15 and we have a rule to ensure our amount variable is between 0 and 15, quite simple.

But how do I write a test to try if the rules works?

We create our rules in:

attached() { 
  ValidationRules.customRule(
  // some rule
  )
  ValidationRules
    .ensure('amount').satisfiesRule('amountRule')
}

Numbers is an array with numbers of 0 to 15

<select value.bind="bag.selectedAmount" class="${!bag.selectedAmount && errors.length > 0 ? 'error-dropdown' : ''} form-control input regular-15-25 select-height"
                id="selectAmount">
                <option value="">Choose</option>
                <option repeat.for="number of numbers" model.bind="number">${number}</option>
             </select>

Do I need to stage the component? Can I just simple do something similar to sut.amountRule(‘amount’)?

Thanks in advance.
