Seems like it's too easy to use
spyOnwhen we shouldn't. Let's blacklist it in favor of explicitly-scoped spy methods.There is a comment in
scripts/jest/setupTests.jsthat I don't understand. It says:Why do we think
spyOnis deprecated? The official Jest docs listjest.spyOnas being available for 19.0.0+. Is this comment maybe referring to the call-through behavioral differences or something?I also updated
scripts/jest/spec-equivalence-reporter/setupTests.jsandscripts/jest/typescript/jest.d.tsalthough neither is necessary at this time.
