Whats the right way to do evals?

[KaviiSuri]

I’m building AI agent that is capable of doing multiple steps in one go and also capable of using a lot of tools. Evals are a standard way to test one shot generations or cot based generations, but there is no clear best practices in docs to be able to test such agents, especially when using streamText and streamObject functions to do the actual requests to llms.

i would appreciate some guidance here
