Recently, I started a new position where my primary project involves working on an Angular web application. This is my first exposure to Angular, so I am in the process of learning the basics.
The main challenge I am facing currently is modifying existing component.spec.ts files to align with the changes I implement in the corresponding component.ts files.
While I believe that my alterations are functioning correctly, the unit tests fail because I suspect that the spec files need adjustments to match my updated code. Despite consulting Angular's testing documentation, I have not been able to make significant progress.
Unfortunately, I cannot share the exact code due to confidentiality reasons, and my knowledge of Angular is not advanced enough to create a mock example. However, if I abstract certain components, perhaps you can provide me with some guidance.
If, for instance, I update an existing component.ts file to include @Input() user: User;
in the export class section, and introduce a method:
ngOnInit() {
this.client = this.allClients[0].client;
this.setClient(this.client);
}
What modifications will be necessary in my spec file to accommodate these changes?
Currently, all 6 unit tests are failing with the error message:
TypeError: Cannot read property '0' of undefined
, which seems to indicate that I am trying to access a 'user' property that was previously unnecessary.
I understand that providing helpful feedback without seeing the entire codebase may be challenging, but any assistance or recommended resources would be greatly valued.
