SyntaxError: /Users/leongaban/projects/Futuratum/moonholdings.io/components/Astronaut/Astronaut.tsx: interface est un mot réservé en mode strict (8: 0)
J'ai essayé de changer strict en false dans les compilerOptions de mon tsconfig mais cela n'a pas aidé.
Quelqu'un d'autre a rencontré cela avec Jest testing et Typescript?
package.json
import React from 'react';
import { shallow } from 'enzyme';
import toJson from 'enzyme-to-json';
import Astronaut from '../components/Astronaut/Astronaut.tsx';
describe('<Astronaut /> component', () => {
console.log('Astronaut', Astronaut);
describe('when rendering', () => {
const wrapper = shallow(<Astronaut showLogo={true} />);
it('should render a component matching the snapshot', () => {
const tree = toJson(wrapper);
expect(tree).toMatchSnapshot();
expect(wrapper).toHaveLength(1);
});
});
});
Mon fichier .babelrc import React from 'react';
import { moonHoldings } from '../../shared/models';
import { astronaut } from '../../styles';
const { AstronautContainer, Heading } = astronaut;
interface LogoCheck {
showLogo: boolean;
}
export default (showLogo: LogoCheck) => (
<AstronautContainer>
{ showLogo.showLogo === true ? <Heading>{moonHoldings}</Heading> : null }
<img src="static/astronaut.png" alt="astronaut" />
</AstronautContainer>
);
3 Réponses :
votre déclaration const n'a pas de nom de variable. Nom de la variable const: Type = nouveau Type () ou const variableName: Type; ou const variableName = nouveau type;
Vous voulez dire cette ligne? const {AstronautContainer, Heading} = astronaut; Je déstructure ces deux noms de variables à partir du fichier de styles d'astronaute.
Ok, après avoir ajouté ce @ babel / preset-typescript dans mes préréglages, cette erreur a disparu:
"test": {
"presets": [
"@babel/preset-typescript", // <---
[
"next/babel",
{
"preset-env": {
"modules": "commonjs"
}
}
]
],
"plugins": [
[
"styled-components",
{
"ssr": true,
"displayName": true
}
]
]
}
Dans le cas où le préréglage @ babel / typescript ne fonctionne pas.
Vous pouvez essayer ce qui suit:
.ts ou .tsx selon que vous avez JSX dans votre test (dans ce cas Astronaut.test.tsx ) "moduleFileExtensions": [
"js",
"ts",
"tsx"
],
On dirait que votre manuscrit n'est pas compilé. Utilisez-vous ts-jest?
J'ai installé ce pack, mais comment l'utilisez-vous @Stramski
J'ai l'extrait suivant dans mon package.json => "jest": {"globals": {"ts-jest": {"tsConfig": "tsconfig_renderer.json"}}, "moduleFileExtensions": ["ts", " tsx "," js "," jsx "]," roots ": [" / test "]," setupFiles ": [" /test/test-setup/test-setup.ts "], "transform": { ". (ts | tsx)": "ts-jest" }, "testRegex": "(/ test /.*)(.test.ts|.test.tsx|.test.js)$ "},
@Stramski ok J'ai essayé d'ajouter vos lignes de transformation et de testRegex, mais maintenant il ne trouve aucun test.
Aucun test trouvé.Parce que mon regex ne correspond pas à vos tests;)
