Yes, you can automate Tableau testing, but it's tricky. Here's what works:
What I've used successfully:
Selenium WebDriver:
Works for Tableau Server/Online dashboards
Can test filters, interactions, data refresh
Good for regression testing of published dashboards
Tableau REST API:
Best for backend testing
Test data source connections, user permissions
Validate workbook publishing/updates
Image comparison tools:
Test Complete, Sikuli for visual validation
Compare chart outputs before/after changes
Catch visual regressions
What's challenging:
Dynamic content:
Charts load at different speeds
Data changes frequently
Hard to get consistent test results
Limited element identification:
Tableau generates complex HTML
Elements don't have stable IDs
Need to use XPath (which breaks often)
My approach:
Use API tests for data validation
Selenium for basic UI interactions
Manual testing for complex visualizations
Focus on critical user workflows
Real talk: Tableau automation is harder than regular web apps. Start with API testing and simple UI flows. Don't try to automate everything - some things are better tested manually.
