Automation Testing using Selenium

It sounds like you're experiencing dynamic changes in the HTML structure of your Power BI report, causing the XPath or CSS selectors to become unreliable. This could happen due to various reasons, such as updates to the Power BI platform or changes in how the report is rendered in the browser.

One alternative approach you could consider is using tools specifically designed for web automation testing, such as Cypress or Puppeteer. These tools offer robust features for interacting with web elements and handling dynamic changes more effectively compared to Selenium.

Cypress, for example, provides automatic retries and built-in waiting mechanisms, which can help mitigate issues caused by dynamic changes in the UI. Additionally, it offers a user-friendly API and comprehensive documentation, making it relatively easy to get started with test automation for your Power BI reports.

By leveraging dedicated web automation testing tools like Cypress or Puppeteer, you may find it easier to maintain reliable and stable test scripts for validating your Power BI reports, even in the face of dynamic changes in the UI.
