AV Tester is a user interaction simulator plugin for WordPress that doesn’t require any special setup. Just install as simply as other plugins and start testing.
To run test, all you have to do is define a series of user actions in dashboard that would be simulated on browser. So you can track if there is any missing things or bugs in new releases of your WordPress plugin or theme.

An automated testing plugin for WordPress CMS that simulates basic user interactions on browser without any crazy setup.

In its current version, O3 CLI Services exposes two WordPress REST API endpoints 
to empower developers and QA engineers to query URL paths of WordPress posts by 
post types, category types, and menus.
<h3>Usage</h3>
Use the /wp-json/o3-cli-api/url-sources API endpoint to get a list of sources of 
URL paths, and use the /wp-json/o3-cli-api/urls API to get a list of URL paths 
of posts in the system, using your sources as URL query parameter filters.
Source filters for /wp-json/o3-cli-api/urls: 
 – post_types 
 – Include a comma-separated list of post type machine names. 
 – categories 
 – Include a comma-separated list of category slugs. 
 – menus 
 – Include a comma-separated list of menu slugs. 
 – limit 
 – Include an integer limit to control the maximum number of URL paths to 
 return for each machine name in any source.
An example request:
GET http://example.com/wp-json/o3-cli-api/urls?post_types=post,product&categories=food,travel&menus=main-navigation,footer-menu&limit=50
The above example requests the URL paths of posts of post types with the machine 
names of ‘post’ and ‘product’, having categories with ‘food’ and ‘travel’ slugs, 
as well as items in menus with ‘main-navigation’ and ‘footer-menu’ slugs. As 
with any WordPress REST API endpoints, the above request returns a JSON array.
The O3 CLI automatically generates requests like the above, and it empowers 
developers and QA engineers to dynamically generate visual regression tests, 
among other needs. See the documentation at 
https://www.npmjs.com/package/o3-cli.
