TS2305: Module '@angular/core/testing' has no exported member async

Question

I updated angular version from 17 to 18 and because of which some modules are no longer supporter especially in spec.ts files while importing them. Like async from @angular/core/testing and **provideRouterTesting **from @angular/router/testing and **HttpClientTestingModule **from @angular/common/http/testing. The exact error messages are as follows

@angular/router/testing' has no exported member provideRouterTesting TS2305: Module '@angular/core/testing' has no exported member async TS6385: HttpClientTestingModule is deprecated.

I need to know the alternatives for these modules. It will be helpful if anyone can update the alternative modules for these.
