I was having trouble with cascading AutoCompletes so I split it out into a simple solution.
I started following this example , but then needed to add an initial selected value.
I’ve put my code on Github at https://github.com/aligneddev/AngularAutoCompleteCascading . Please see the readme for more information.
I’ve added an article about using Testing Library with Angular and added tests to this repo.
