Greg Magolan 5f0d5e9ccf build: update to nodejs rules 0.34.0 and bazel 0.28.1 (#31824)
nodejs rules 0.34.0 now includes protractor_web_test_suite rule (via new @bazel/protractor rule) so we switch to that location for that rule in this PR so that /packages/bazel/src/protractor can be removed in a future PR

this PR also brings in node toolchain support which was released in nodejs rules 0.33.0. this is a prerequisite for RBE for mac & windows users

bazel schematics also updated with the same. @bazel/bazel 0.28.1 npm package includes transitive dep on hide-bazel-files so we're able to remove an explicit dep on that as well.

Integration tests for Angular

This directory contains end-to-end tests for Angular. Each directory is a self-contained application that exactly mimics how a user might expect Angular to work, so they allow high-fidelity reproductions of real-world issues.

For this to work, we first build the Angular distribution just like we would publish it to npm, then install the distribution into each app.

To test Angular CLI applications, we use the integration test cli-hello-world. When a significant change is released in the CLI, the application should be updated with ng update:

$ cd integration/cli-hello-world
$ yarn install
$ yarn ng update @angular/cli @angular-devkit/build-angular
# yarn build
# yarn test
# typescript version

Render3 tests

The directory cli-hello-world-ivy-compat contains a test for render3 used with the angular cli.

The cli-hello-world-ivy-minimal contains a minimal ivy app that is meant to mimic the bazel equivalent in packages/core/test/bundling/hello_world, and should be kept similar.

Writing an integration test

The API for each test is:

  • Each sub-directory here is an integration test
  • Each test should have a package.json file
  • The test runner will run yarn and yarn test on the package

This means that the test should be started by test script, like

"scripts": {"test": "runProgramA && assertResultIsGood"}

Note that the package.json file uses a special file://../../dist scheme to reference the Angular packages, so that the locally-built Angular is installed into the test app.

Also, beware of floating (non-locked) dependencies. If in doubt you can install the package directly from file:../../node_modules.

Running integration tests

$ ./integration/run_tests.sh

The test runner will first re-build any stale npm packages, then cd into each subdirectory to execute the test.
