Pete Bacon Darwin cd449021c1 feat(ivy): ngcc - compile only specified package.json format properties (#29092)
You can now specify a list of properties in the package.json that
should be considered (in order) to find the path to the format to compile.

The build marker system has been updated to store the markers in
the package.json rather than an additional external file.
Also instead of tracking the underlying bundle format that was compiled,
it now tracks the package.json property.

BREAKING CHANGE:

The `proertiesToConsider` option replaces the previous `formats` option,
which specified the final bundle format, rather than the property in the
package.json.
If you were using this option to compile only specific bundle formats,
you must now modify your usage to pass in the properties in the package.json
that map to the format that you wish to compile.

In the CLI, the `--formats` is no longer available. Instead use the
`--properties` option.

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.
