JDN is a Google Chrome plugin developed by jdn-publishers that aims to help Test Automation Engineers in creating Page Objects and speeding up test development. With JDN, engineers can enhance the experience of the Page Objects TF layer creation process.

The latest update to JDN introduces the "Vividus" framework, with "Selenium" and "Selenide" already in development. It also adds a new "FindBy" annotation and allows users to create an Empty Page Object and manually select the necessary locators from the coverage. Shortcuts using Enter and Esc keys in modal windows have been added, as well as CTRL+Z for text input editing. Group functions like Delete, Restore, and Advanced Calculation are now available, and these functions also work on site coverage. The update also includes bug fixes and many other small improvements.

JDN provides automatic recognition of objects on web pages, Java code creation for UI testing of web objects, and the ability to manage objects while creating code. It also recognizes MUI, Vue.js, and HTML5 elements.
