### Setting up core tests

- 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();

```

## Contributing a new test

- In your branch create a new `example-test-name.test.js` under the `tests/e2e/core-tests/specs` folder.
- 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 `tests/e2e/core-tests/specs/index.js`
```js
const runExampleTestName = require( './grouping/example-test-name.test' );
// ...
module.exports = {
// ...
    runExampleTestName,
}
```
