# Example app with Jest tests
|
|
|
|
## How to use
|
|
|
|
### Using `create-next-app`
|
|
|
|
Execute [`create-next-app`](https://github.com/segmentio/create-next-app) with [Yarn](https://yarnpkg.com/lang/en/docs/cli/create/) or [npx](https://github.com/zkat/npx#readme) to bootstrap the example:
|
|
|
|
```bash
|
|
npx create-next-app --example with-jest with-jest-app
|
|
# or
|
|
yarn create next-app --example with-jest with-jest-app
|
|
```
|
|
|
|
### Download manually
|
|
|
|
Download the example [or clone the repo](https://github.com/zeit/next.js):
|
|
|
|
```bash
|
|
curl https://codeload.github.com/zeit/next.js/tar.gz/canary | tar -xz --strip=2 next.js-canary/examples/with-jest
|
|
cd with-jest
|
|
```
|
|
|
|
Install it and run:
|
|
|
|
```bash
|
|
npm install
|
|
npm run dev
|
|
# or
|
|
yarn
|
|
yarn dev
|
|
```
|
|
|
|
## Run Jest tests
|
|
|
|
```bash
|
|
npm run test
|
|
# or
|
|
yarn test
|
|
```
|
|
|
|
## The idea behind the example
|
|
|
|
This example features:
|
|
|
|
* An app with jest tests
|
|
|
|
> A very important part of this example is the `.babelrc` file which configures the `test` environment to use `babel-preset-env` and configures it to transpile modules to `commonjs`). [Learn more](https://github.com/zeit/next.js/issues/2895).
