+# E2E tests
+
+
+## Directory structure
+
+- `test-app-v10`: example app using Angular v10 with basic setup with `jest` and `jest-preset-angular`.
+- `test-app-v9`: example app using Angular v9 with basic setup with `jest` and `jest-preset-angular`.
+
+
+## Running tests
+
+You run the tests on example apps with `yarn test:e2e` (or `npm run test:e2e)`. In `scripts/lib/paths.js`,
+`projectsToRun` must be modified if a new project is added to `e2e`.
+
+What will happen in order is as following:
+
+1. A bundle (we'll call it `[bundle]`) will be created for `jest-preset-angular` using `npm pack` (`yarn pack` is buggy).
+
+    The `prepare` script will be run, so `clean` and `build` (that is why e2e tests are launched before the others, since it's building as part of the process)
+
+2. `npm ci` and `npm install --save-dev [bundle]` will be run in each project directory in `e2e` directory.
+3. each test suite in each example project are run according to `jest` config of that project.
+
+
+## Why
+
+E2E tests being in a temporary folder of the operating system ensure none of the parents would be containing `node_modules`.
+
+Having the test cases outside of `[jest-preset-angular]` project's root ensures it won't fallback the resolution of node modules within dev dependencies of `jest-preset-angular` itself.
+
+Not to mention that using `npm pack` ensure those tests cases have the same version of `jest-preset-angular` as the one we would publish on NPM.

+# TestAppV10
+
+This project was generated with [Angular CLI](https://github.com/angular/angular-cli) version 10.0.2.
+
+## Development server
+
+Run `ng serve` for a dev server. Navigate to `http://localhost:4200/`. The app will automatically reload if you change any of the source files.
+
+## Code scaffolding
+
+Run `ng generate component component-name` to generate a new component. You can also use `ng generate directive|pipe|service|class|guard|interface|enum|module`.
+
+## Build
+
+Run `ng build` to build the project. The build artifacts will be stored in the `dist/` directory. Use the `--prod` flag for a production build.
+
+## Running unit tests
+
+Run `ng test` to execute the unit tests via [Karma](https://karma-runner.github.io).
+
+## Running end-to-end tests
+
+Run `ng e2e` to execute the end-to-end tests via [Protractor](http://www.protractortest.org/).
+
+## Further help
+
+To get more help on the Angular CLI use `ng help` or go check out the [Angular CLI README](https://github.com/angular/angular-cli/blob/master/README.md).
