Single version update Angular

Asked 2022-Mar-30 at 11:59

i have to update an angular 7.x project to angular 8.2.0, so i've read online of ng update.

I have a global angular version equal to my update target version (8.2.0) but ng update forces me to update to the latest version.

That is because when you do ng update you are not defining a specific version. You should use something like ng update @angular/core@10 @angular/cli@10 etc...

Its not recommended to go from Angular 7 to Angular 13 in a single update, instead you should go version by version like:

Angular 7 -> Angular 8,
Angular 8 -> Angular 9.1

Follow this Angular Update Guide and you should be fine, at the bottom you have specific instructions you should do before each update https://update.angular.io/

Create mocked service (object) with one method returning a value

Asked 2022-Mar-09 at 21:07

In an Angular environment, how can I very easily create in a Jest environment a mocked service for a service object returning a specific value? This could be via Jest of ng-mocks, etc.

You need to use MockBuilder to mock the service, and MockInstance to customize it.

Also getCount is an observable, therefore its mock should return Subject, which we can manipulate.

Mocking generated API service

Asked 2022-Mar-09 at 21:06

In our Angular application, we are using services generated from API and we're facing issues with the unit tests for components or custom services that utilize them.

ANSWER

Answered 2022-Mar-06 at 22:05

The problem here is that typescript aggregates all parameters and all return types. Therefore, its mock should also follow the aggregated type.

In this case, (_: 'body') => of(CONNECTION_MOCK) is just 1 of 3. Typescript expects _ to be 'body' | 'response' | 'events', and the same happens with the return type: all 3 should be respected.

All that leads to the point that it's simpler to use as never, because it's hard to implement the desired callback.

what you are looking for is MockBuilder.

With its help you need only a component and its module, the rest will be mocked automatically by default.

QUESTION

How to check inner component's method is called during tests?

Asked 2021-Jul-19 at 07:43

I have a component (MapComponent) that calls external API via HexesService. Results of Data of this API call are loaded to some buttons (View Map, Edit Map). I have another internal component (HexesComponent) and clicking on a View button makes a call to this internal component (which in turn makes another API call and displays the data inside of HexesComponent).

I've created a test with a mock of external service. My test checks that after the main component is loaded it makes call to the mocked service and loads data properly (all buttons are populated). This works perfectly fine.

The next thing I'd like to check that click on the button makes a call to a method of the HexesComponent.

The problem I have is that my internal component is always undefined. I've created a stub for my internal component, but this did not help: even the stab is empty.

Question #1: What do I do wrong? I've tried using async for the method inside the 'beforeEach', this did not help.

Needless to say that outside of 'tests', the functionality works perfectly fine.

Question #2: How to validate that clicking on the button leads to the call of 'loadMap' method of the HexComponent?

Here is the code of my test:

Rather than pushing for an option to use Stabs, I decided to give it another try and make it work with ng-mocks.

Apparently, my question is a close to Mocking Child Components - Angular 2 and the good guidance is https://www.npmjs.com/package/ng-mocks/v/11.1.4 The difference is in my case, I also need to ensure I call some methods of the child component.

To help someone else (and maybe myself in future) here is a list of issues I've encountered on my way.

Install ng-mocks using "npm install ng-mocks --save-dev" command
Add import lines (obvious, but VS Code did not autosuggest those and I struggled to realize how to get access to exact classes I needed):

this issue has been fixed recently. In your case, it means that ComponentName has been imported wrongly, or has a wrong type.

You're on the right track!

Step 1.

The classes ConfigurationSection and ConfigurationProperty are in SF namespace System.Fabric.Description. Add a using for the namespace

Step 2.

Please upgrade to ServiceFabric.Mocks v4.2.8. This adds support to mock the DataPackage property on MockCodePackageActivationContext. See this page for an example.

Step 3.

Use the created context as a constructor argument. Change this code:
