+## Config testIdAttribute
+
+If you would like to change the default testId from `data-testId` to `data-test-id`, add to your project's `cypress/support/index.js`:
+
+```javascript
+import {configure} from '@testing-library/cypress'
+configure({testIdAttribute: 'data-test-id'})
+```
+
+It accepts all configurations listed in [DOM testing library](https://testing-library.com/docs/dom-testing-library/api-configuration).
