Description

Since Release 1.0.0, none of my tests pass, there is an exemple with a really simple one

Steps to Reproduce

// simplified test case
it('Component rendered', () => {
        const element = createElement('c-info-GSL', {
            is: InfoGSL
        });
        document.body.appendChild(element);

        expect(element.shadowRoot.querySelector("lightning-record-view-form")).not.toBeNull();
    });
<!-- HTML for component under test -->
<template>
    <div class="acc-container">
        <lightning-record-view-form record-id={recordId} object-api-name="Account">
            <div class="slds-grid">
                <div class="slds-col slds-size_1-of-2">
                    <lightning-output-field field-name="ID_SL__c"></lightning-output-field>
                </div>
                <div class="slds-col slds-size_1-of-2">
                    <lightning-output-field field-name="Price__c"></lightning-output-field>
                </div>
            </div>
        </lightning-record-view-form>
    </div>
</template>
// JS for component under test
import { LightningElement,api } from 'lwc';

export default class AccInfoGSL extends LightningElement {
    @api recordId;
}
// Jest config overrides (if any)
# Command to repro
sfdx-lwc-jest -- --no-cache

Expected Results
