Apply Cypress Testing Library to the existing E2E tests

[luixxiul]

matrix-org/matrix-react-sdk#10446 implemented Cypress Testing Library to align Jest tests and Cypress tests in terms of using Test Library (#24906 (comment)), and I think Cypress Testing Library should be applied to not only a new test but also the existing tests.

• Here is the list of commands provided by the library: https://github.com/testing-library/cypress-testing-library/blob/next/cypress/integration/find.spec.js

Here is a list of the current Cypress E2E tests.

Please note that some of them do not require Cypress Testing Library, as they do not emulate interactions by users.

Have you considered any alternatives?

@luixxiul Thanks for writing the list about what to migrate. I would suggest that you pause your work on this issue for a few days until a decision on convenience functions has been made.

I understood. Fortunately it looks fairly easy to replace the lines of the existing PRs with regex in any case :-)

Edit: the functions have been removed.
