FAQPage Schema
How do I write end-to-end tests for Vaadin applications using TestBench?▼

End-to-end tests for Vaadin applications use TestBench to implement Page Object patterns and ElementQuery logic, ensuring stable element queries during real-browser execution. This approach validates critical user flows within Vaadin 25 apps.

Does TestBench support JUnit 5 for running Vaadin browser tests?▼

TestBench supports both JUnit 4 and JUnit 5 for executing Vaadin browser tests. You can integrate Page Object design and ElementQuery patterns with either framework to validate critical user flows.

What is the best way to structure Page Objects for Vaadin TestBench?▼

Using the TestBench Element API alongside ElementQuery patterns is the best way to structure Page Objects for Vaadin. This design creates maintainable, reliable tests for critical user flows and cross-browser validation.

Can I perform visual regression checks with Vaadin TestBench?▼

You can perform visual regression checks with Vaadin TestBench to ensure UI consistency. The testing framework supports visual validation alongside real-browser execution and cross-browser testing for Vaadin 25 apps.

Why are my Vaadin TestBench element queries failing during real-browser execution?▼

Vaadin TestBench element queries often fail during real-browser execution if the TestBench Element API is not properly applied. Using structured Page Object patterns and ElementQuery logic ensures stable, reliable element retrieval.
