## E2E tests
|
|
|
|
|
|
|
|
|
|
There are four different sets of e2e tests in this folder. They are all testing different
|
|
|
|
|
translation scenarios, but they are all built with IVY enabled.

### runtime

|
|
|
A new `polyfills.ts` file is provided (`polyfills-runtime.ts`) which is swapped in by a file
|
|
|
|
|
replacement in the `angular.json` configuration. In this new file:
|
|
|
|
|
* Runtime translations are provided (`loadTranslations()`).
|
|
|
|
|
* The current locale is set (`$localize.locale = 'fr'`) and loaded (`registerLocaleData(localeFr);`)

### de and fr
|
|
|
|
|
|
|
|
|
|
The application is built (into the `dist` folder) and then two sets of translations
|
|
|
|
|
(`src/locales/messages.(de|fr).json`) are used to generate two copies of the app, which have
|
|
|
|
|
been translated (compile-time inlined).
|
|
|
|
|
|
|
|
|
|
These translated apps are stored in `tmp/translations/(de|fr)`.
|
|
|
|
|
|
|
|
|
|
### legacy
|
|
|
|
|
|
|
|
|
|
The legacy `ng xi18n` tool extracts the messages from the Angular templates, into the XLIFF 1.2
|
|
|
|
|
format with legacy message ids (`tmp/legacy-locales/messages.legacy.xlf`).
|
|
|
|
|
|
|
|
|
|
The translation file is modified to apply a simple translation.
|
|
|
|
|
|
|
|
|
|
The app must be compiled using the `i18nLegacyMessageIdFormat` option set to ensure that the correct
|
|
|
|
|
message ids are used to match those in the translation files.
|
|
|
|
|
|
|
|
|
|
The app is translated using the compile-time inlining tool to generate a copy that has the
|
|
|
|
|
translated message in it.
|
|
|
|
|
|
|
|
|
|
## Hosting
|
|
|
|
|
|
|
|
|
|
Since the CLI hosts from and in-memory file-system the compile-time inliner is not able to
|
|
|
|
|
translate the output files. So the `de`, `fr` and `legacy` apps must be statically built to
|
|
|
|
|
disk and translated there.
|
|
|
|
|
|
|
|
|
|
Since the translated app is now on disk, we cannot use the CLI to serve it. Instead we use
|
|
|
|
|
a simple static HTTP server instead.
