1. Is this request related to a challenge you're experiencing? Tell me about your story.

Dify is becoming increasingly unstable due to contributions. Even though the project is still in an early development phase, Dify is already being used in production environments.
Especially recently, breaking changes and critical errors have been introduced that have caused problems for many users.

2. Additional context or comments

In coordination with @guchenhe, I will set up a comprehensive test setup with Cypress.io that will enable us to cover entire features in Dify with tests. A GitHub workflow that runs tests for each PR ensures that existing features do not break.

3. Can you help us with this feature?

• I am interested in contributing to this feature.
