O que costuma-se supor

A test setup file configured under setupFiles has access to test framework globals like beforeEach, afterEach, and expect.extend.

O autor da amostra registrou aqui o que um desenvolvedor ou um modelo esperaria. O contrato abaixo é o que de fato rodou.

Contrato

• assert running Jest with test framework hooks in setupFiles fails with ReferenceError: beforeEach is not defined because the framework environment is not yet initialized
• assert setupFiles executes in the isolated test environment before the test framework and can configure environment globals
• assert setupFilesAfterEnv executes after test framework initialization, allowing beforeEach hooks and expect.extend matchers to run across test suites
• assert jest-config normalize correctly resolves <rootDir> tokens for both setupFiles and setupFilesAfterEnv into absolute paths
