See [code](https://github.com/welldone-software/babel-plugin-react-add-test-id/blob/master/src/index.js#L84): ```javascript path.node.openingElement.attributes.push( // VVV t.jSXAttribute(t.jSXIdentifier(attrName), testId) ); ``` Shouldn't that be `t.jsxAttribute` (based on [the babel docs](https://babeljs.io/docs/en/babel-types#jsxattribute))?
