TypeScript compiler will now build to ES2015 code and modules. Babili is used to minify ES2015 code, providing an initial optimization that we couldn't previously get just from Uglify. Uses Babel to convert ES2015 to UMD/ES5 code, and Uglify to minimize the output.

# 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.
|
|
|
|
## 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-shrinkwrapped) dependencies. If in doubt
|
|
you can install the package directly from `file:../../node_modules`. For example,
|
|
this is useful for protractor, which has a slow post-install step
|
|
(`webdriver-manager update`) that can be skipped when the package from
|
|
Angular's `node_modules` is installed.
|
|
|
|
## Running integration tests
|
|
|
|
The first time you run the tests, you'll need some setup:
|
|
|
|
```shell
|
|
$ ./integration/build_rxjs_es6.sh
|
|
```
|
|
|
|
Now you can iterate on the tests by keeping the dist folder up-to-date.
|
|
See the `package.json` of the test(s) you're debugging, to see which dist/ folders they install from.
|
|
Then run the right `tsc --watch` command to keep those dist folders up-to-date, for example:
|
|
|
|
```
|
|
$ ./node_modules/.bin/tsc -p modules/@angular/core/tsconfig-build.json --outDir dist/packages-dist/core --watch
|
|
```
|
|
|
|
Now you can run the integration test, it will re-install from the dist/ folder on each run.
|
|
|
|
```
|
|
$ ./integration/run_tests.sh
|
|
```
