webforJ Testing

Testing in webforJ apps involves a combination of unit and end-to-end (E2E) testing to ensure a stable and reliable app. Each type of testing serves a distinct purpose in maintaining app quality.

Unit testing​

Unit testing focuses on verifying individual components or backend logic in isolation. By following standard Java testing practices, such as using JUnit, developers can efficiently validate specific app logic and ensure that each "unit" performs as expected.

End-to-End (E2E) testing​

End-to-end testing is important for validating the user experience in webforJ apps, which generate dynamic, single-page web interfaces. These tests simulate user interactions and verify the features of the entire app.

Using tools like Selenium and Playwright, you can:

  • Automate browser interactions, such as button clicks and form submissions.
  • Verify consistent rendering and interactivity of dynamic UI components.
  • Ensure behavior consistency across different browsers and devices.

Combining testing strategies​

By combining unit and E2E testing:

  1. Isolate Issues: Detect and resolve component-level bugs early with unit testing.
  2. Ensure Reliability: Validate complete user journeys and system integrations with E2E testing.
