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
- JavaScript
- TypeScript
// jest.config.js
module.exports = {
//...
globalSetup: 'jest-preset-angular/global-setup',
};
// jest.config.ts
import type { Config } from 'jest';
const jestConfig: Config = {
//...
globalSetup: 'jest-preset-angular/global-setup',
};
export default jestConfig;
Control ngcc processing
Since v12.0.0, jest-preset-angular
provide a possibility to skip ngcc
via globalThis
by doing the following
- JavaScript
- TypeScript
// 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',
};
// jest.config.ts
import type { Config } from 'jest';
globalThis.ngJest = {
skipNgcc: true,
tsconfig: 'tsconfig.spec.json', // this is the project root tsconfig
};
const jestConfig: Config = {
//...
globalSetup: 'jest-preset-angular/global-setup',
};
export default jestConfig;
