While working with jest and typescript, I encountered an issue when using "before" calls:
Cannot find name 'before'.ts(2304)
I made sure to have @types/jest installed already.
Update: It appears that jest does not have a "before" function - it could be leftover tests from another testing framework. Therefore, Typescript was correct in identifying the missing function.
Take a look at these available global methods, you won't find a before method there. It seems like you might be interested in the beforeAll method instead.
