How would you leverage JavaScript to automate testing for a web application that dynamically loads content based on user interaction?

To automate testing for a web application with dynamic content loading, using JavaScript Event Listeners is effective. Event Listeners can capture user interactions and trigger actions in response, allowing automation scripts to adapt to dynamic content changes. JavaScript Executions in Selenium can execute JavaScript code but may not be as versatile for handling dynamic content. Integrating JavaScript with TestNG and using JavaScript with Apache JMeter are not specific to Selenium automation and may not provide the needed flexibility for handling dynamic content.
