Angular Ivy

important

This step is OPTIONAL

Starting from v9.0.0+, jest-preset-angular is fully compatible with Angular Ivy. To make sure that Jest uses the Angular Ivy, you must run ngcc before running tests. ngcc will transform all Angular-format packages to be compatible with Ivy compiler.

jest-preset-angular also provides a Jest global setup file to help you to run ngcc with Jest. Add to the following section:

  • to your root Jest config
// jest.config.js
module.exports = {
//...
globalSetup: 'jest-preset-angular/global-setup',
};

Control ngcc processing

Since v12.0.0, jest-preset-angular provide a possibility to skip ngcc via globalThis by doing the following

// jest.config.js
globalThis.ngJest = {
skipNgcc: true,
tsconfig: 'tsconfig.spec.json', // this is the project root tsconfig
};

module.exports = {
//...
globalSetup: 'jest-preset-angular/global-setup',
};
