Migrate test files to Typescript

[grunch]

All tests should be typescript, after we implement this all new test must be written on typescript

Hi @grunch , will the tests in typescript still using sinon and mocha? or they can be changed to jest, for example

I don't recommend jest, my team has had to move away from it. We're using vitest now.

Yes, for me it's ok to use vitest, I don't have any prefered test framework
