Some suggestions for examples

[rafaelss95]

• Replace fireEvent.blur(htmlElement) by htmlElement.blur() (https://testing-library.com/docs/guide-events/#focusblur);
• Replace findBy*/getBy*/queryBy* by screen.*;
• Add more examples in forms (mainly in material version):
  • Tests using mat-error for each form-field instead of a block of errors;
  • Tests with form-friendly components, like checkbox, datepicker, chips, slider, button-toggle, autocomplete.

Note that if you like the idea, I can submit a PR ASAP.

Thanks for the suggestions, we would love to have these!
Also, TIL for the blur. I do think we'll have to test it out for ATL, since this wouldn't trigger a change detection AFAIK.

Closing this issue because it's been inactive.
To test forms, you can take a look at A practical guide to Angular Template-Driven Forms, which has some tests in the examples.
