# Puppeteer Angular Schematic
Adds Puppeteer-based e2e tests to your Angular project.
## Getting started
Run the command below in an Angular CLI app directory and follow the prompts.
> Note this will add the schematic as a dependency to your project.
```bash
ng add @puppeteer/ng-schematics
```
Or you can use the same command followed by the [options](#options) below.
Currently, this schematic supports the following test frameworks:
- [**Jasmine**](https://jasmine.github.io/)
- [**Jest**](https://jestjs.io/)
- [**Mocha**](https://mochajs.org/)
- [**Node Test Runner** _(Experimental)_](https://nodejs.org/api/test.html)
With the schematics installed you can run E2E tests:
```bash
ng e2e
```
### Options
When adding schematics to your project you can to provide following options:
| Option | Description | Value | Required |
| -------------------- | ----------------------------------------------------------------------------------------------------------------------- | ------------------------------------------ | -------- |
| `--isDefaultTester` | When true, replaces default `ng e2e` command. | `boolean` | `true` |
| `--exportConfig` | When true, creates an empty [Puppeteer configuration](https://pptr.dev/guides/configuration) file. (`.puppeteerrc.cjs`) | `boolean` | `true` |
| `--testingFramework` | The testing framework to install along side Puppeteer. | `"jasmine"`, `"jest"`, `"mocha"`, `"node"` | `true` |
| `--port` | The port to spawn server for E2E. If default is used `ng serve` and `ng e2e` will not run side-by-side. | `number` | `4200` |
## Creating a single test file
Puppeteer Angular Schematic exposes a method to create a single test file.
```bash
ng generate @puppeteer/ng-schematics:test "<TestName>"
```
### Running test server and dev server at the same time
By default the E2E test will run the app on the same port as `ng start`.
To avoid this you can specify the port the an the `angular.json`
Update either `e2e` or `puppeteer` (depending on the initial setup) to:
```json
{
"e2e": {
"builder": "@puppeteer/ng-schematics:puppeteer",
"options": {
"commands": [...],
"devServerTarget": "sandbox:serve",
"testingFramework": "<TestingFramework>",
"port": 8080
},
...
}
```
Now update the E2E test file `utils.ts` baseUrl to:
```ts
const baseUrl = 'http://localhost:8080';
```
## Contributing
Check out our [contributing guide](https://pptr.dev/contributing) to get an overview of what you need to develop in the Puppeteer repo.
### Sandbox
For easier development we provide a script to auto-generate the Angular project to test against. Simply run:
```bash
npm run sandbox -- --init
```
After that to run `@puppeteer/ng-schematics` against the Sandbox Angular project run:
```bash
npm run sandbox
# or to auto-build and then run schematics
npm run sandbox -- --build
```
To run the creating of single test schematic:
```bash
npm run sandbox:test
```
### Unit Testing
The schematics utilize `@angular-devkit/schematics/testing` for verifying correct file creation and `package.json` updates. To execute the test suit:
```bash
npm run test
```
