Jest failed to parse a file. This happens e.g. when your code or its dependencies use non-standard JavaScript syntax, or when Jest is not configured to support such syntax. |
|
|
|
Out of the box Jest supports Babel, which will be used to transform your files into valid JS based on your Babel configuration. |
|
|
|
By default "node_modules" folder is ignored by transformers. |
|
|
|
Here's what you can do: |
|
${DOT}If you are trying to use ECMAScript Modules, see ${_chalk().default.underline( |
|
'https://jestjs.io/docs/ecmascript-modules' |
|
)} for how to enable it. |
|
${DOT}If you are trying to use TypeScript, see ${_chalk().default.underline( |
|
'https://jestjs.io/docs/getting-started#using-typescript' |
|
)} |
|
${DOT}To have some of your "node_modules" files transformed, you can specify a custom ${_chalk().default.bold( |
|
'"transformIgnorePatterns"' |
|
)} in your config. |
|
${DOT}If you need a custom transformation specify a ${_chalk().default.bold( |
|
'"transform"' |
|
)} option in your config. |
|
${DOT}If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the ${_chalk().default.bold( |
|
'"moduleNameMapper"' |
|
)} config option. |
|
|
|
You'll find more details and examples of these config options in the docs: |
|
${_chalk().default.cyan('https://jestjs.io/docs/configuration')} |
|
For information about custom transformations, see: |
|
${_chalk().default.cyan('https://jestjs.io/docs/code-transformation')} |
|

${_chalk().default.bold.red('Details:')} |
