## Pre-requisites
### Setting up the test environment
Follow [E2E setup instructions](https://github.com/woocommerce/woocommerce/blob/trunk/plugins/woocommerce/tests/e2e/README.md).
### Setting up core tests
#### Version 0.2.0 or newer
Version 0.2.0 added a test installer that will populate the `tests/e2e/specs` folder with test scripts for all the current core test suite. It also creates sample configuration files including all the configuration data needed to run the core tests.
- Install the e2e-environment `npm install @woocommerce/e2e-environment --save-dev`
- Run the installer `npx wc-e2e install @woocommerce/e2e-core-tests`
- Merge the sample configuration files:
- `tests/e2e/docker/woocommerce.e2e-core-tests.sh` => `initialize.sh`
- `tests/e2e/config/default-woocommerce.e2e-core-tests.json` => `default.json`
#### Version 0.1.X or other test runner
- Create the folder `tests/e2e/specs` in your repository if it does not exist.
- To add a core test to your test suite, create a new `.test.js` file within `tests/e2e/specs` . Example code to run all the shopper tests:
```js
const { runShopperTests } = require( '@woocommerce/e2e-core-tests' );
runShopperTests();
```
## Retrying/Re-running tests

## Contributing a new test
- In your branch create a new `example-test-name.test.js` under the appropriate folder in the [`specs`](specs) directory.
- Jest does not allow its global functions to be accessed outside the jest environment. To allow the test code to be published in a package import any jest global functions used in your test.
```js
const {
it,
describe,
beforeAll,
} = require( '@jest/globals' );
```
- Wrap your test in a function and export it
```js
const runExampleTestName = () => {
describe('Example test', () => {
beforeAll(async () => {
// ...
});
it('do some example action', async () => {
// ...
});
// ...
});
});
module.exports = runExampleTestName;
```
- Add your test to [`specs/index.js`](specs/index.js)
```js
const runExampleTestName = require( './grouping/example-test-name.test' );
// ...
module.exports = {
// ...
runExampleTestName,
}
```
