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

# The admin user's username or generated consumer key

# The admin user's password or generated consumer 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:

BASE_URL=http://localhost:8086 USER_KEY=admin USER_SECRET=password npm run e2e: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 installed and activated on the test site.

For more information about authentication with the WooCommerce API, please see the 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:

npm run e2e:hello

This tests connectivity to the API by validating connection to the following:

Run all tests

To run all of the API tests, you can use the following command:

npm run e2e: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:

npm e2e -- --group=orders

Alternatively, you can use jest to run test groups:

jest --group=api

Writing tests


  1. All tests should be placed in the tests directory.
  2. Always provide a JS doc in all tests, and tag them with @group. See the Test groups section for more info on grouping tests.
  3. Use functions in the data folder when generating test data instead of constructing them from scratch within the test.
  4. Use functions in the endpoints folder to send requests instead of directly using SuperTest's request() function.
  5. Use describe.each() or it.each() when writing repetitive tests.
  6. Always clean up all test data generated by the 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:

 * 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.

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:

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);

Creating test data

Most of the time, test data would be in the form of a request payload. Instead of building them from scratch inside the test, create a test data file inside the data directory. Create a model of the request payload within that file, and export it as an object or a function that generates this object.

Afterwards, make sure to add the test data file to the data/index.js file.

This way, the test data would be decoupled from the test itself, allowing for easier test data management, and more readable tests.

Creating endpoint functions

All functions for sending requests to endpoints should be placed in the endpoints directory.

Newly created files should be added to the endpoints/index.js file.

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.


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.


This package makes use of the SuperTest HTTP assertion package. For more information on the response properties that are available can be found in the SuperAgent documentation.

For the list of WooCommerce API endpoints, expected responses, and more, please see the WooCommerce REST API Documentation.
