# Using the Built In Container for End to End Testing
This document provides general instructions for using `@woocommerce/e2e-environment` with the built in hosting container.
## Prerequisites
Complete the [setup instructions](./README.md) in each project/repository.
## Initialization Requirements
The test sequencer uses a `ready` page to determine that the testing environment is ready for testing. This page is created by the built in initialization. It matches the following spec:
```
wp post create --post_type=page --post_status=publish --post_title='Ready' --post_content='E2E-tests.'
```
### Project Initialization
Each project will have its own begin test state and initialization script. For example, a project might start testing expecting that the [sample products](https://github.com/woocommerce/woocommerce/tree/trunk/sample-data) have already been imported. Below is the WP CLI equivalent of the built in initialization script for WooCommerce Core E2E testing:
```
wp core install --url=http://localhost:8084 --admin_user=admin --admin_password=password --admin_email=wooadmin@example.org
```
Project specific initialization can be added through an executable file at ```tests/e2e/docker/initialize.sh```. WooCommerce core's script is:
```
#!/bin/bash
echo "Initializing WooCommerce E2E"
wp plugin activate woocommerce
wp theme install twentynineteen --activate
wp user create customer customer@woocommercecoree2etestsuite.com \
--user_pass=password \
--role=subscriber \
--first_name='Jane' \
--last_name='Smith' \
--path=/var/www/html
# we cannot create API keys for the API, so we using basic auth, this plugin allows that.
wp plugin install https://github.com/WP-API/Basic-Auth/archive/master.zip --activate
# install the WP Mail Logging plugin to test emails
wp plugin install wp-mail-logging --activate
```
### Adhoc Initialization
The container build script supports an initialization script parameter
```shell script
npx wc-e2e docker:up tests/e2e/docker/init-wp-beta.sh
```
This script updates WordPress to the latest nightly point release
```shell script
#!/bin/bash
echo "Initializing WooCommerce E2E"
wp plugin install woocommerce --activate
wp theme install twentynineteen --activate
wp user create customer customer@woocommercecoree2etestsuite.com --user_pass=password --role=customer --path=/var/www/html
# we cannot create API keys for the API, so we using basic auth, this plugin allows that.
wp plugin install https://github.com/WP-API/Basic-Auth/archive/master.zip --activate
echo "Updating to WordPress Nightly Point Release"
wp plugin install wordpress-beta-tester --activate
wp core check-update
```
### Container Configuration
The built in container initialization needs to know the particulars of your test install to run the tests. The built in uses the following default settings:
```
{
"url": "http://localhost:8084/",
"appName": "{repository-folder-name}",
"users": {
"admin": {
"username": "admin",
"password": "password",
"email": "admin@woocommercecoree2etestsuite.com"
}
}
}
```
You can override these in `/tests/e2e/config/default.json`.
- The `appName` entry is optional. If present, it is used as a prefix for the docker container names.
- The `customer` entry is not required by the sequencer but is required for the core test suite.
- The test sequencer does not use the user account email addresses.
```
{
"url": "http://localhost:8089/",
"users": {
"admin": {
"username": "admin",
"password": "password",
},
"customer": {
"username": "customer",
"password": "password",
}
}
}
```
### Folder Mapping
The built in container defaults to mapping the root folder of the repository to a folder in the `plugins` folder. For example `woocommerce` is mapped to `/var/www/html/wp-content/plugins/woocommerce`. Use the `WC_E2E_FOLDER_MAPPING` environment variable to override this mapping.
- Storefront Theme - ```WC_E2E_FOLDER_MAPPING=/var/www/html/wp-content/themes/storefront npx wc-e2e docker:up```
- Site Project - ```WC_E2E_FOLDER_MAPPING=/var/www/html/wp-content npx wc-e2e docker:up```
### Travis CI Supported Versions
Travis CI uses environment variables to allow control of some software versions in the testing environment. The built in container supports these variables:
- `WP_VERSION` - WordPress (default `latest`)
- `TRAVIS_PHP_VERSION` - PHP (default `latest`)
- `TRAVIS_MARIADB_VERSION` - MariaDB (default `latest`)
### Travis CI
To enable Travis CI testing in your repository add the following to the appropriate sections of your `.travis.yml` config file.
```yaml
version: ~> 1.0
include:
- name: "Core E2E Tests"
php: 7.4
env: WP_VERSION=latest WP_MULTISITE=0 RUN_E2E=1
....
script:
- npm install jest --global
- npx wc-e2e docker:up
- npx wc-e2e test:e2e
....
after_script:
- npx wc-e2e docker:down
```
