# WooCommerce Core API Test Suite
|
|
|
|
This package contains automated API tests for WooCommerce.
|
|
|
|
## Environment variables
|
|
|
|
Before running the tests, the following environment variables need to be configured as shown in `.env.example`:
|
|
|
|
```
|
|
# Your site's base URL, not including a trailing slash
|
|
BASE_URL="https://mysite.com"
|
|
|
|
# The admin user's username or generated consumer key
|
|
USER_KEY=""
|
|
|
|
# The admin user's password or generated consumer secret
|
|
USER_SECRET=""
|
|
```
|
|
|
|
For local setup, create a `.env` file in this folder with the three required values described above.
|
|
|
|
Alternatively, these values can be passed in via the command line. For example:
|
|
|
|
```shell
|
|
BASE_URL=http://localhost:8084 USER_KEY=admin USER_SECRET=password npm run test:api
|
|
```
|
|
|
|
When using a username and password combination instead of a consumer secret and consumer key, make sure to have the [JSON Basic Authentication plugin](https://github.com/WP-API/Basic-Auth) installed and activated on the test site.
|
|
|
|
For more information about authentication with the WooCommerce API, please see the [Authentication](https://woocommerce.github.io/woocommerce-rest-api-docs/?javascript#authentication) section in the WooCommerce REST API documentation.
|
|
|
|
### Optional variables
|
|
|
|
The following optional variables can be set in your local `.env` file:
|
|
|
|
* `VERBOSE`: determine whether each individual test should be reported during the run.
|
|
* `USE_INDEX_PERMALINKS`: determine whether to use index permalinks (`?p=123`) for the API route.
|
|
|
|
## Running tests
|
|
|
|
### Test API connection
|
|
|
|
To verify that everything is configured correctly, the following test script is available:
|
|
|
|
```shell
|
|
npm run test:hello
|
|
```
|
|
|
|
This tests connectivity to the API by validating connection to the following:
|
|
|
|
* A non-authenticated endpoint: [Index](https://woocommerce.github.io/woocommerce-rest-api-docs/?javascript#index)
|
|
* An endpoint requiring authentication: [System status properties](https://woocommerce.github.io/woocommerce-rest-api-docs/?javascript#system-status-properties)
|
|
|
|
### Run all tests
|
|
|
|
To run all of the API tests, you can use the following command:
|
|
|
|
```shell
|
|
npm run test:api
|
|
```
|
|
|
|
### Running groups of tests
|
|
|
|
To run a specific group of tests, you can use the `npm test -- --group=` command and pass in the group's name you want to run.
|
|
|
|
For example, if you wanted to only run the orders API tests, you can use the following:
|
|
|
|
```shell
|
|
npm test -- --group=orders
|
|
```
|
|
|
|
Alternatively, you can use `jest` to run test groups:
|
|
|
|
```shell
|
|
jest --group=api
|
|
```
|
|
|
|
## Writing tests
|
|
|
|
### Test groups
|
|
|
|
This package makes use of the `jest-runner-groups` package, which allows grouping tests together around semantic groups (such as `orders` API calls, or `coupons` API calls) to make running test suites more granular.
|
|
|
|
Before the `describe()` statement, add in a doc block containing the desired groups:
|
|
|
|
```javascript
|
|
/**
|
|
* Tests for the WooCommerce API.
|
|
*
|
|
* @group api
|
|
* @group endpoint
|
|
*
|
|
*/
|
|
describe('', () => {
|
|
it('', async () => {});
|
|
});
|
|
```
|
|
|
|
The `api` group should be included on all tests that should be run with the rest of the test suite. Groups can also contain a path, such as `orders/delete`.
|
|
|
|
For more information on how groups work, please refer to the [`jest-runner-groups` documentation](https://www.npmjs.com/package/jest-runner-groups).
|
|
|
|
## Using query strings
|
|
|
|
For tests that use query strings, these can be passed into the `getRequest()` method using an object of one or more key value pairs:
|
|
|
|
```javascript
|
|
const { getRequest } = require('./utils/request');
|
|
|
|
const queryString = {
|
|
dates_are_gmt: true,
|
|
after: '2021-05-13T19:00:00',
|
|
before: '2021-05-13T22:00:00'
|
|
};
|
|
|
|
const response = await getRequest('/orders', queryString);
|
|
```
|
|
|
|
## Debugging tests
|
|
|
|
You can make use of the REST API log plugin to see how requests are being made, and check the request payload, response, and more.
|
|
|
|
[REST API Log](https://wordpress.org/plugins/wp-rest-api-log/)
|
|
|
|
## Generate a Postman Collection
|
|
|
|
This package also allows generating a `collection.json` file using the test data in this package. This file can be imported into Postman and other REST clients that support the Postman v2 collection. To generate this file, run:
|
|
|
|
```
|
|
npm run make:collection
|
|
```
|
|
|
|
This will output a `collection.json` file in this directory.
|
|
|
|
## Resources
|
|
|
|
This package makes use of the [SuperTest HTTP assertion package](https://www.npmjs.com/package/supertest). For more information on the `response` properties that are available can be found in the [SuperAgent documentation](https://visionmedia.github.io/superagent/#response-properties).
|
