# 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
|
|
```
