* build_bazel_rules_typescript renamed to npm_bazel_typescript * build_bazel_rules_karma renamed to npm_bazel_karma * browser_repositories.bzl removed and now using @npm_bazel_karma//:browser_repositories.bzl * includes some fixes for future ts_library devmode es2015 support but some failure still remain when devmode is es2015 so this PR keeps it as es5 using the bazelOptions.devmodeTargetOverride tsconfig setting PR Close #28896
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 hello_world_cli contains a test for render3 used with the angular cli.
If the Angular CLI is modified to generate a render3 application this should be replaced with that project.
If the render3 is updated to support the Angular 5 bootstrap a version of this project should be created that uses the Angular 5 bootstrap.
Writing an integration test
The API for each test is:
- Each sub-directory here is an integration test
- Each test should have a
package.jsonfile - The test runner will run
yarnandyarn teston 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.
