Liam DeBeasi 093c671e3e test(angular): remove routing waits in tests (#28532)
Issue number: N/A

<!-- Please do not submit updates to dependencies unless it fixes an
issue. -->

<!-- Please try to limit your pull request to one type (bugfix, feature,
etc). Submit multiple pull requests if needed. -->

## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->

Our Angular E2E tests are brittle because they rely on arbitrary
`cy.wait` calls to account for asynchronous routing. This leads to flaky
tests on CI and seemingly random test failures when we make adjustments
to the Ionic Anguar routing integration (see:
https://github.com/ionic-team/ionic-framework/pull/28188)

Additionally, our test execution for the navigation tests is quite slow
because transitions are enabled. As a result, we need to wait hundreds
of ms per test just for the transitions to finish.

## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->

- Updated the `testStack` command to use a new `getStack` [Cypress
query](https://docs.cypress.io/api/cypress-api/custom-queries). These
queries come with automatic retrying built-in. By leveraging this query
in the `testStack` command, we can avoid the arbitrary waits.
- Added `ionic:_testing=true` query strings to the navigation tests.
This causes Ionic to disable any transitions so the tests execute
faster.
- Removed most of the arbitrary `cy.wait` calls. I kept the swipe to go
back `cy.wait` -- I wasn't quite sure how to reduce flakiness on that
one.

## Does this introduce a breaking change?

- [ ] Yes
- [x] No

@ionic/angular

Ionic Angular specific building blocks on top of @ionic/core components.

Testing ng-add in ionic

  1. Pull the latest from main
  2. Build ionic/angular: npm run build
  3. Run npm link from ionic/angular/dist directory
  4. Create a blank angular project
ng new add-test
// Say yes to including the router, we need it
cd add-test
  1. To run schematics locally, we need the schematics-cli (once published, this will not be needed)
npm install @angular-devkit/schematics-cli
  1. Link @ionic/angular
npm link @ionic/angular
  1. Run the local copy of the ng-add schematic
$ npx schematics @ionic/angular:ng-add

You'll now be able to add ionic components to a vanilla Angular app setup.

Project Structure

common

This is where logic that is shared between lazy loaded and standalone components live. For example, the lazy loaded IonPopover and standalone IonPopover components extend from a base IonPopover implementation that exists in this directory.

Note: This directory exposes internal APIs and is only accessed in the standalone and src submodules. Ionic developers should never import directly from @ionic/angular/common. Instead, they should import from @ionic/angular or @ionic/angular/standalone.

standalone

This is where the standalone component implementations live. It was added as a separate entry point to avoid any lazy loaded logic from accidentally being pulled in to the final build. Having a separate directory allows the lazy loaded implementation to remain accessible from @ionic/angular for backwards compatibility.

Ionic developers can access this by importing from @ionic/angular/standalone.

src

This is where the lazy loaded component implementations live.

Ionic developers can access this by importing from @ionic/angular.
