@atomic-testing/angular-core

Shared implementation core for the Angular adapters of Atomic Testing. It provides:

• AngularInteractor — extends DOMInteractor and settles Angular change detection after every interaction via ApplicationRef.whenStable(), which is correct under both zone.js and zoneless change detection.
• createTestEngine — bootstraps a standalone component through Angular's real bootstrap API (createApplication + ApplicationRef.bootstrap, not TestBed) and returns a TestEngine. When zone.js is not loaded, provideZonelessChangeDetection() is added automatically.
• createRenderedTestEngine — wraps an element rendered by an Angular app bootstrapped elsewhere.

Do not depend on this package directly

Install the package matching your Angular major instead — each pins the correct @angular/* peer range and re-exports this package's entire surface:

Angular major	Package
20	@atomic-testing/angular-20
21	@atomic-testing/angular-21
22	@atomic-testing/angular-22

This mirrors the react-core / react-18 / react-19 layering; see ADR-013 (agent-docs/adr/013-angular-shared-core-thin-packages.md) for the rationale.

Usage

See the per-major package READMEs, or the validation fixture in package-tests/angular-20-test for a runnable example covering both zone.js and zoneless configurations.
