How to update to the latest version of ng-mocks

Usually, you can use the latest version of ng-mocks with any Angular 5+ application.

Below you can find critical changes. They happen on major releases.

If you are facing an issue, despite the instructions, please, feel free to contact us.

From any old one to 12.4.0​

Because of issues with the speed of merging a fix for jest, there is a braking change in 12.4.0.

If you are using MockInstance in beforeAll, beforeEach or it, and rely on automatic reset, then you have to perform extra configuration. More information in the How to install ng-mocks and in MockInstance.scope sections.

From 11 to 12​

The only breaking change is auto-spy.

ngMocks.autoSpy('jasmine') and ngMocks.autoSpy('jest') should be used instead of import 'ng-mocks/dist/jasmine'; and import 'ng-mocks/dist/jest';.

From 11.10 to 11.11 and higher​

If you are facing an issue with MockRender and a thrown error about "Forgot to flush TestBed?", you may want to suppress it instead of fixing, whereas fixing it is the right way.

In order to suppress the error, you need to upgrade to 12.0.1 at least, and to add in test.ts:

ngMocks.config({
  onTestBedFlushNeed: 'warn',
});

Then instead of throwing errors, MockRender will log them in console as warnings.

From 10 to 11​

MockModule​

Now it does not export all mock imports and mock declarations, but respects exports of modules. The story is the same as in the update from 8 to 9 for MockBuilder.mock.

If you still need to export them, then you should consider a migration of affected tests to MockBuilder or ngMocks.guts.

MockHelper​

MockHelper has been renamed to ngMocks, please check its docs.

MockComponent​

Previously, it had been accepting a meta parameter, now it has been removed.

Contact us, if you are using this functionality.

Tokens​

From 9 to 10​

There are no special cases. The update should be straight forward.

From 8 to 9​

from MockModule to MockBuilder.mock​

MockModule exports all imports and declarations, and MockBuilder.mock respects exports of modules.

This behavior allows tests to fail, if a declaration of a module has been changed, and it does not export a dependency anymore. Likewise, an Angular application would fail too.

From 7 to 8​

There are no special cases. The update should be straight forward.
