docs: clarify mocking differences with jest

[sparten11740]

Closes #17

[mvayngrib]

@marcoskichel you ran into mocking incompatibility issues recently, can you see if this guide suffices for you to get your tests working?

[marcoskichel]

It helps, but if I am honest I don't think it suffices 😢

If we allow users to implement tests as if using jest, we probably want the tool to behave exactly like it (or at least very close to that).

Is there any technical reason why we can't or don't want to handle hosting like jest does?

[sparten11740]

we probably want the tool to behave exactly like it (or at least very close to that).

When using jest ESM, it behaves the same as exodus-test and also requires to import dynamically after the mock has been defined. Hoisting happens only when running jest as CJS (the default)

Oh, really? I wasn't aware 😅 , nevermind me then.
