Dedicated documentation for Testing Tanstack applications.

[ShayokhShorfuddin]

Hello there. Just recently, I was searching for resources/tutorials on how to implement unit tests and E2E tests (Jest/Playwright) in Tanstack Start. I was not able to find any appropriate resource at all. All I could see were GitHub issues/Stack Overflow posts of developers who broke their app while trying to test. The developer experience is not seamless at all.

Furthermore, this absence of official documentation or blog posts/articles from the maintainer makes it hard for developers to feel confident about building their next big project (or migrating existing ones) to Tanstack Start/Router.

I would humbly like to draw the attention of the maintainers. A few dedicated resources on these libraries/packages would be lovely:

1. Jest
2. Vitest
3. React Testing Library
4. Cypress
5. Puppeteer
6. Mocha
7. Jasmine
8. Chai

Tanstack is great. Testing will make it greater! 🏖️

yes this needs to be done for sure.

Oh yes, that would be great. I am using Playwright for E2E tests with Tanstack Start, but I really struggle with flaky tests due to hydration and client-side routing. Some guidance would help a lot.
