Using React Native with Jest and TypeScript, when trying to run the tests I get:
Test suite failed to run [BABEL] unknown: Preset /* your preset */ requires a filename to be set when babel is called directly, babel.transform(code, { filename: 'file.ts', presets: [/* your preset */] }); See https://babeljs.io/docs/en/options#filename for more information.Any idea what can cause this?
This is my jest section on package.json:
"jest": {"preset": "react-native","roots": ["<rootDir>/__tests__" ],"setupFiles": ["<rootDir>/scripts/jest/setup.js","<rootDir>/node_modules/appcenter/test/AppCenterMock.js","<rootDir>/node_modules/appcenter-analytics/test/AppCenterAnalyticsMock.js","<rootDir>/node_modules/appcenter-crashes/test/AppCenterCrashesMock.js","<rootDir>/node_modules/appcenter-push/test/AppCenterPushMock.js","<rootDir>/node_modules/react-native-localization.js","./config/jest/mock.fetch.js","./config/jest/react-native-localization.js" ],"moduleFileExtensions": ["ts","tsx","js" ],"transform": {"^.+\\.(js)$": "<rootDir>/node_modules/babel-jest","\\.(ts|tsx)$": "<rootDir>/node_modules/ts-jest/preprocessor.js" },"collectCoverage": true,"coverageDirectory": "coverage","coverageReporters": ["text-summary","html" ],"testPathIgnorePatterns": ["\\.snap$","<rootDir>/node_modules/","<rootDir>/lib/" ],"collectCoverageFrom": ["**/*.{js,jsx}","artifacts/**/*.js","!artifacts/**/*.spec.js","!artifacts/**/*.index.js","!<rootDir>/node_modules/" ] },and this is my babel.config.js file:
module.exports = { presets: ['module:metro-react-native-babel-preset' ], plugins: ['babel-plugin-transform-typescript-metadata', ['@babel/plugin-proposal-decorators', { legacy: true }] ],};
