How can I simulate HTTP error response in Angular service? I often need to handle different HTTP error codes and sometimes I need implement solution, but backend is not ready. How can I mock errors from backend? Example code
public getData(): Observable<Response> {
return this.httpClient.get<Response>(`${this.endpoint}`);
}
Simplest solution - you can create an HttpErrorResponse instance, set error status and then return this object as service fake response.
public getData(): Observable<Response> {
const error = new HttpErrorResponse({ status: 422 });
return of(error) as any;
}
or
public getData(): Observable<Response> {
const error = new HttpErrorResponse({ status: 422 });
return throwError(error) as any;
}
